[MUSIC]

This week we're gonna do something brand spanking new.

I don't know how many of you all know the name Tom Christie, if I just say his name.

But Tom Christie is the person who created Jengo REST framework.

Which we have used on this stream before,

I'm sure you have all heard of Django REST framework.

So he got it into his head a little while back to do a new API framework

without having to be built on top of Django or Flask or anything like that.

He wanted it to be just an API framework,

just straight framework doing whatever he wanted.

And so he created this one called API Star.

And I haven't really gotten to play with it much yet.

But I talked to Tom a little bit at PyCon

last week and I wanna just give it a try.

So that's what we're gonna do.

We're gonna just give it a try.

So we are going to do this, still haven't figure

out how to do this quickly and safely through,

The PyCharm, that's what this thing is called.

And then we'll see what we're getting ourselves into cuz,

like I said, I haven't played with this at all.

I have no clue what's going on in here.

So we're gonna just try it out, see what it's like.

And then, if we can get it working well enough, I'm gonna try and

do some sort of little like single page web app kind of thing with it.

I want to play with Vue.js which I have also not ever used.

So, between those two we'll

end up with two things I have never used and hopefully something that works.

So let me slide this over here a little bit, let's pop open this terminal and

let's see if we can generate this thing.

So we'll do apistar, no, we have to install apistar.

That would be handy first.

All right, Settings.

Not Version Control.

Project Interpreter, and it's at a plus sign and let's look for apistar.

There it is, we'll go ahead and install that.

And we are on version 0.1.17.

So if you're wanting to follow along that's the version to install.

It was [INAUDIBLE] the newest one.

And as far as I know this is all we have to have to start.

So we're gonna start doing just a plain static hardcoded JSON API,

not pulling from a database or anything like that.

And then once we get it going and

working out then we'll see what we can do as far as a database back end.

I talked to Tom a little bit last night and he said there were,

There were a few things that weren't working great with models, so

we're gonna just leave those alone for now.

All right, so if we look here we now have an app.py and we have a tests.py.

So a test.py is kind of cool.

We have this data welcome.

We pull in welcome from the app so here's welcome and

let's see, I need to make this way smaller so

that I can see your chat and I can see this part.

All right, cool.

So you can see that we have this welcome function

here where it takes a name that's defaulting to None.

If the name is None then it just comes back with welcome to API Star.

Otherwise we come back with welcome to API Star and whatever name somebody put in.

And we're putting this into a message key in a dict.

So then we have some routes.

So our first route is forward slash, which that gets welcome.

And then we include the docs routes and the static routes at docs and static.

And then we make our app, and we set the routes equal to the routes.

Okay, that seems fairly straightforward.

I don't see anything there that I'm like immediately lost on.

And then let's check out the tests, so we test welcome, so

we have data where we just call the welcome function.

And then we assert that data is welcome to API, is the dict with welcome to API Star

which, since we didn't pass in a name is what we would get, and then we test it.

So we should be able to do, take this, paste the new one in,

[SOUND] and we should be able to do test welcome name.

And we should be able to do like test_welcome_name,

and we could say name = Kenneth, and

this should be Welcome to API Star, Kenneth.

All right, yeah, making sure I was spelling all of that right.

So then if we were to run our unit tests.

That's true, those are not unit tests.

How do we run those tests?

We just run API Star tests.

Okay.

Python?

Custom.

No, wait, wait. We don't want that as Python tests.

We want, to just run,

You know what, we're just gonna do it in here.

apistar test.

There we go, so we ran our three tests and we're good.

So it looks like that's using py test.

So I can probably do edit configs,

add a py.test.

Let's see if that one works.

[SOUND], whatever, we'll figure that out later.

All right, so haxmat wants me to do something with Go.

If I knew anything at all about Go I would but I don't.

I don't know anything about Go and this video will end up on YouTube.

You'll be able to watch the whole thing on YouTube later on.

And I don't know about it being on the Treehouse site.

We were talking about doing something there, but

it's definitely gonna be on YouTube.

Okay, and so let's look at this other test here which is,

this is the http_request test.

So we make a test client just like we would do in Django.

We try to get local hosts.

We make sure it comes back with a 200 and

we make sure it comes back with Welcome API Star.

All right, so that is pretty cool.

You all feel like you get an idea of how this is done and how this is done?

If you feel like you're still lost let me know, but I'm gonna go ahead and

I'm gonna try to run this thing.

I didn't wanna open that image.

So I wann do apistar run and

then, What happened here?

Non UTF-8 code starting with something there.

No encoding.

Interesting.

What if I just did like python app.py?

No.

Okay, let's see

what's going on here.

Learn Go like I did Rust.

You know what, I might, not today.

Not today, but maybe I will.

We'll find out.

Yeah, what happened there?

Let's just search for Windows.

No, nothing.

Non UTF-8.

No, weird.

Okay, what's up, Tom?

This thing should be, this thing should be working.

Weird, okay, I'm gonna try this in a different shell.

Let's try this not inside the PyCharm Shell,

because sometimes the PyCharm Shell is iffy.

Sometimes it just doesn't do the things I want it to do.

Are we good?

Okay, api, no wait what do we call this?

game_api, that was it and then I need to

do .Virtualenvs Is game API

scripts activate.ps1.

And then API star run.

[SOUND] Got that again.

All right, let's grab this and see what we've got.

Alright, while vaka two,

yeah we're definitely using python

today, I can't go edit an exe,

that's not how exes work.

Okay.

Apistar run non UTF-8.

Isn't it great?

When we hit these little things, don't you all love this?

And see, yeah, APIStar is pretty new.

So we probably aren't gonna find a thing.

[MUSIC]

I saw some people talking about Hug yesterday, so

I want to check that one out too, just in case.

Maybe we do hug instead because we're having issues with, we

can't we're having issues getting this to run.

Hopefully Tom is watching cuz I was talking about this yesterday and

Tom will be like, "Hey dude, here's what you're doing wrong.

Any luck?

You there Tom?

Yes, something is weird here.

Because it doesn't run.

[MUSIC]

Hi Py three support.

[MUSIC]

Sorry for just having to look for this everybody.

But that's what happens.

You're gonna go on a rant about how great go is.

I'd really rather you not.

I mean go is fine.

But that doesn't mean that I wanna listen to a rant about it.

Game_api/Scripts.

Okay.

Can I cat api/star.exe?

Right.

That's not like I can go and edit that.

What was it that I did the other day?

It was open

Atem APIstart exe.

No? Okay.

Whatever.

Let's go here, and

let's go here and here and

here and here and here and here and

I want to open with that.

Sure let's open that with code.

Invite Tom to co-stream, yeah I might could.

It is a binary, but that doesn't mean I don't want you to open it.

I still want you to open it.

Can we drop it into here?

No.

Edit with VIM, this better not be running it in DOS mode,

yeah, see that does me no good, okay.

So How do we fix that?

Let's go look at what we're doing when we install this.

Okay, api star.coi main.

Main, so we set up Python Path, we get the app path.

App = App, and then we try to do App.click.

So he's using click somewhere?

Come on, I should be able to do API star, if I can do API star test

I can do new.

I can run the test suite.

Why doesn't it run?

Line 1, non-UTF-8 code starting with \x90.

Python 3.6.

Okay, so let's see path to six three,

non UTF 8 binary are executable,

let's see if we can solve this?

Maybe there's a way for us to fix this, everybody.

And if there's not then

we'll try something different.

Not a Python script so python will just run it as that.

[MUSIC]

Yeah, that's what I was doing, but,

Okay, let's just try it like this.

C/users.kennan.virtualenvs.

Game API, scripts API star dot EXE.

Run.

Nope same thing.

Alright, so that didn't work.

Why is it trying to run it like python though.

Like I'm getting obviously a python

[MUSIC]

Error here.

[MUSIC]

What I really wish I could do is just do Python.

Apistar app.py.

And the module name, api star main, api star as a package cannot be,

okay, so what about just app.py?

That doesn't do anything.

That has no idea what I'm talking about.

[MUSIC]

And that does exactly that.

Tom, Tom, Tom, Tom, Tom.

You know what? Let's try this.

Tom https://twitter.com/tomchristie.

I think that's it. There may be an underscore in there.

Yep, that's not him.

I think there's an underscore right there.

That's him!

Let's send them a message, I'm getting an error about

non ETF 8,

code NV API, start of EXE, any ideas?

You're live on stream.

All right.

Let's see if he says anything.

[LAUGH] All right but you know what?

If he doesn't we'll give him a couple of minutes to answer and if he doesn't then

Yeah, adding an issue pause would make the most sense,

but I wanna interrupt his day [LAUGH].

To some degree.

I don't think an issue would be a bad thing.

What I'm interested in though, is how it's actually building the things.

So.

Publish.

That's not doing what I want.

That's just him publishing his thing, okay.

So what we're actually wanting is what's inside API star and then command.

What's in here?

Run run run run run, from APSR get current app, app equals get current app.

Now it's running for me click that echo starting up.

So then he does this run simple from verkzug.

Almost wonder if I could fake that.

I shouldn't have to fake that though.

All right let's try this.

Let's try doing python, import apistar

apistar.commands.

Run.run simple?

Nope, dot run.

Okay, so we need to do local host.

And we need to do 80 80.

An integer is required.

Okay.

Can't find main module in blank.

That's true.

Also, let's open up the discussion page here.

So that's if we wanted to drop down the WSGI,

which we don't want to at the moment.

So that's the development server which we're already having problems with.

So that's not what we want.

All right, so what I'm wondering is if we could

up here do something like from api star.Commands import run.

And if we go back and look at what run was doing.

Where were we looking at that?

Welcome to hacking somebody else's software, y'all.

Not normally what I would be doing, but

I don't necessarily feel like I have something else I can do.

Okay.

So, then okay,

no this is pie charm.

Andy okay.

So then could we do, wait wait wait.

We have an app.

Sorry, let me hop over here and look at this thing.

So we have an app, right?

So we imported app, I'm assuming we have an app right there, we do.

Does an app have a run command?

Browse commands What can I do there?

[SOUND] Python.

We'll do the Python consul here.

There we go, import app.

App.app.run no commands.

Function new, function okay, app.app.run.

App object.commands.run.

Aw!

Wait, wait, wait.

Let me, that is not what I meant to do.

Import app.

Okay and then here, let's do local host.

And then local host.

Aw, man.

[LAUGH] Thought I was right,

thought I was gonna be right, I was not right.

Tom still hasn't responded which that's cool.

He's got stuff to do and he's in like the UK too anyway.

So I'm guessing

That doing that one probably doesn't do what I wanted.

Search Windows, no results found.

Really?

UTF8 No results found,

non UTF-8.

No results found.

Why would it fail for us, but not be failing for anybody else?

Anybody wanna wager a guess on that one?

Let's just search for win.

Name API Star Logging Serverless deployment, no.

Okay so, We can do those commands.

And we get a thing here but

we don't really get the thing that we're looking for.

Just got a buzz on my phone.

Tom?

No, it doesn't know what we're talking about.

Fun, no none.

Let's try reinstalling.

So let's go here, API star.

Let's delete API star.

And, let's reinstall api star.

Yeah, pause, it could be that they're using, that they're not using Windows.

Right, no such option to clean.

That's so weird.

Non UTF-8 code, starting with /x90

on line 1 but no encoding declared.

Okay,

I wonder if it would be possible to do, what kind of scripts do we get?

If any.

And I'm not gonna work on this too much longer because if we're

not getting anything, then we're not getting anything.

Those are his scripts setup.py.

Okay, so if we look in here there is a little substance installed,

we had entry points, api*.cli.main

Yeah.

All right, well I guess we will try something different then.

It's kinda disappointing, I've been having a lot of streams lately

where we get three things and we can't finish something.

Which is really too bad.

Let's try out hug Let's try out this hug thing.

So we'll still do this as our game API thing.

But we will install hug instead

of I mean yeah, we need Pip.

We need setup tools.

We don't need any of the rest of those.

Let's just try reinstalling everything.

And let's just see what happens.

I don't think that's going to matter at all.

Yeah.

Let's try it one more time.

Just one more go, cuz I'd love to see this work.

Also, I could try a different terminal, not that I think it would matter.

Or get bash.

All right, into there, okay.

So then source.

.virtualenvs/game_api/Scripts/activate.

Ps1 no?

No, okay.

Game_api/scripts/apistar,

What's this apistar script?

Let's see what this thing is.

Okay, first of all though,

.virtualENVs/scripts, Nope,

game_api/script, activate.ps1?

No, .bat?

I don't want you to open that file.

There we go.

apistar does that work?

It does, okay.

F: Projects game_api, dir apistar run.

Still gonna get that same thing, okay.

So that's fine I guess.

If I come over here and

I close all this and

I hop into here, no.

Scripts\ and that was apistar-script.py.

Can't open that.

Yeah, cuz you're Windows, okay.

Okay, run.

Ugh, [LAUGH]

so close.

Let's try opening up that file, though.

Let's see if we can do that.

So I'm gonna go there and

then I wanna go into virtualenvs, game api scripts.

API let's try that one.

That is definitely not a thing, so let's do the thing we gotta do.

Open that.

Hey Maurine, how are you doing?

That all looks like UTF-8 though.

What's not UTF-8 there?

It's not the bang pound, right?

That makes no sense.

Let's try

the Latin one.

That's all ASCII, it's definitely all ASCII.

Let's stick that in.

Okay.

Okay.

Of course that doesn't do it, because, you know.

What is \x90?

Hex?

Device control string?

Device control string.

That makes sense.

So with the bold dollar sign.

Hey Nev Miguel, these come up weekly.

Not every week is me, but it is weekly, yeah.

Pause, what's up with that bold dollar sign?

I am not seeing a bold, that one there?

That's just syntax highlighting for,

For this.

Let's.

Yeah, display all those.

Okay, python.exe, does that work?

Does that do anything?

No, what about pythonw?

No.

Okay, source,

virtualenvs/game_api Scripts.

I don't have a way to do activate in here.

Okay what if I don't source this?

How do I get,

Right, that's not gonna work.

Python -m venv venv let's just do this.

Let's do this the old school way that I know to do this.

See if it works.

Currently not working.

Okay, there we go.

Did we get?

We did source venv/bin,

[MUSIC]

Maybe encode the string in UTF-8,

is PyCharm using your system default encoding?

Marine, we're getting the same thing whether I run it in

any of a random number of terminals or what.

So I don't think it's,

[MUSIC]

I don't think it's that.

[MUSIC]

No matter where we run it, we're getting the same thing.

[MUSIC]

Right, okay.

Yeah, this isn't doing what I want.

So why isn't this working?

[MUSIC]

If I do Python, I get that, okay, cool.

So if I do

.virtualenvs\game_api\Scripts\python.exe,

I get that, okay, as I should.

So if I do that and then do that,

game_api\Scripts\apistar-script.py, I

get that.

And if I get that and do run, I get no app.py module exists.

Cool, we're a step closer.

So now let's go in here and run that again.

[MUSIC]

Exact same thing.

Okay, app.py, we don't have anything weird on our line 1.

Everything here is exactly what we got given earlier, okay?

[MUSIC]

Okay, and if I do,

[MUSIC]

This apistar.exe, that's fine.

See this is what's so weird, right, because,

[MUSIC]

I will read your thing here in the second poss, that looks useful.

[MUSIC]

Okay, a magic comment must be placed into the source file either as the first or

second line in the file, such as # coding = encoding name.

Right, which we did that with this thing here, right?

To aid with platforms such as Windows which add Unicode BOM marks to

the beginning of Unicode files, the UTF-8 signature \xef\xbb\xbf will be interpreted

as Unicode 8 encoding as well, even if no magic encoding comment is given.

[MUSIC]

No.

Okay, we're just not gonna worry about this for now.

I will talk to Tom, we will figure out what is going on.

We're going to try out,

[MUSIC]

We're gonna try out hug instead.

[MUSIC]

Yeah, this is just weird.

I don't know why this is failing.

[MUSIC]

And if you try running API start script-exe.

[MUSIC]

We don't have a script.exe, so we just have those two.

[MUSIC]

/apistar run?

[MUSIC]

No we don't have a command for that.

[MUSIC]

No app module exists, yeah, we'll figure it out later.

I will talk to Tom, I will figure out what he is doing or

not doing there that we have missed.

But let's try out hug for now, we've got an hour and 15 left, let's try out hug.

So let's go to our settings.

And we don't need any of these, except for we need pip and we need setuptools.

So the rest of those can go away.

Honestly, I really don't know why this didn't work.

Yep, let's add hug, that's all we have to do, okay.

So then we can go and build, and I really, apistar was cool,

I really liked the thing.

I have a Linux virtual machine that I could try and do this on.

But I don't necessarily wanna try and do that at the moment,

because we'd have to mess with a bunch of stuff.

And you all would get really bored with all the stuff I was messing with.

So let's not do that.

All right, let's try this instead.

So we'll make a thing here, so we'll do import hug.

And we do @hug.get.

And we say what the things is.

And let's just call this hello and name=None.

And we'll return message,

and this will say Hello from Hug!

If name is None, we'll do that.

Otherwise we'll return {'message': 'Hello from Hug,

{name}, we'll make this an f string.

And we'll put that there, okay.

[MUSIC]

Okay, so let's see if this works.

And then we have to run that with hug -f app.py.

[MUSIC]

Access is denied?

[MUSIC]

Access is denied for what?

[MUSIC]

For hug script.

[MUSIC]

Let's restart the terminal here.

[MUSIC]

Can't pickle module objects when API, what?

[MUSIC]

All right, now look you all,

there's no reason to treat Windows as some second class thing.

Minimal Hug program not working on Windows 10.

Uh-huh, hey look, they've got something pretty similar to what I did.

[MUSIC]

hug -f app.py --manual_reload.

Sure, Python, you can access the Internet, that's fine.

[MUSIC]

Okay, so now it says I should be able to go here, and get that.

We got a thing, and if I did name,

nope, name=Kenneth.

[MUSIC]

All right, so there we go, we got a thing, right?

[MUSIC]

So cool, something came up.

[LAUGH] We have to manually reload,

which is not fun, but that's fine.

We can manually reload if we need to.

[MUSIC]

Okay, we're good, right?

We can get ourselves back.

Okay, so that's installing hug, that's our basic thing here.

How do we accept,

[MUSIC]

How do we accept arguments on our line there?

So we can run it with uwsgi things, which that's cool.

[MUSIC]

We can do type annotations, that's fun.

[MUSIC]

We can do all sorts of different things.

[MUSIC]

Okay, and so that's cool.

So then we can do Like output equals

hug.output_format.json, so

that way it knows that it's outputting JSON, let's open this up,

and network refresh.

All, if we look here, we get a document.

Our response headers are application/json, so nice.

So it gave us application/json as the response.

So cool, that works like I would expect.

I didn't restart, so that's kind of funny that that even worked.

[SOUND]

Let's try

that again.

Maybe it does JSON by default.

And then we can do input formatters so that we control how the input comes in.

And we can split it up and we can do that.

There was A sync, which is cool.

All right.

[MUSIC]

Okay, so I'm assuming it, just by default, sends out JSON.

I wonder what the examples thing is?

That's interesting.

Okay, so that's our Quick Start.

Architecture, And that's cool.

So we can bring in a command line one, let's try that too.

@hug.cli(), yeah, sure.

if _ _ name _ _ == '_ _main_ _': Not add,

it would be hello.interface.cli.

Okay.

So, that's cool.

So, now, I should be able to go here and

I should be able to do app.py, what does that do?

That just wants to open it using Visual Studio.

I don't need you to open it using Visual Studio, why don't I just do app?

No.

That sends back that, name=Kenneth.

Cool, okay, that's neat.

That's a cool little feature.

And I can still hit it from a url as well.

Okay.

So, I can do it as either an external API, or

I can do it as a command line interface.

That's kinda neat.

Okay, that's a cool idea.

Looks like it's routing again here.

Okay, so there's that.

So then I can also declare a router for like this.

Okay, can train routers.

Okay, I'm not gonna worry about that for now.

Transform output requires, ACDP router.

These docs are really hard to read.

It would be nice to not have such hard to read docs, hug.

I wanna be able to provide an argument to the URL.

But it doesn't look like I can do that.

Cuz what I'd like to be able to do is go hello/Kenneth.

Which I realize that's not currently running.

That's still gonna die, yep.

So yeah, I'd like to be able to go /hello/kenneth and

it knows what I'm trying to do.

So like this would be hello.

Come on.

That's really annoying.

Right, so let's see, it doesn't know what I'm doing there.

So it knows it can take a name but not,

Not, It doesn't know

how to take that extra argument, which is too bad.

Because that will be cool and nice to have.

So technical's routing again.

It seems like it should be in routing.

Okay, so we go to there and that does that, but

then we can also do one separate like this.

Hug routers, because they're so powerful, is duplication between routers.

For instance, if you decide you want every router to run the 404 page.

Okay, so we're just defining this thing here, and

then we're adding to the URLs like that.

Yeah, okay.

Function to call on the data returned by the function to transform it.

Output format to apply requires list of things

have to be there, can actually get, so on and so forth.

Things that we're able to make.

Ha, there we go.

When blank notation is found in the URL, that's not exactly what I want.

But I can do

/name?

And then, okay, so that worked.

And then if I go to just hello, that one fails because it expects that.

But I bet I can do that.

That one works.

That one works.

That one works.

That one works.

Okay, so we have a thing that works for this.

It's a little weird, but it works.

Yeah, that's just strange.

That's just strange.

[LAUGH] I don't wanna try and do the virtual ENV thing or

not virtual ENV, the virtual box.

I don't know that I could enough done on that to make it,

unless you all wanna to help me figure it out.

So it's been quite a while since I've done like shared folders and stuff like that.

So if you all are down with helping me, get it all running,

then we will do Python running on a virtual machine and

editing the code on Windows and testing it within our Windows browser.

So let me know in chat if you're down for that,

if not, we'll play a little bit more with Hug and see what we can do there.

So I'll give you a couple minutes for chat and I think I saw some questions earlier.

So I'm gonna scroll back up through text here, and see what I see,

Gal, I answered that one a while ago

[SOUND] I mentioned people talking about Go a way back, yeah.

All right, so it says we've got new messages, okay, Paul says shared folders,

let's do it, let's just test this out.

So we're gonna do API Star, we're gonna do VirtualBox stuff instead,

so let's get VirtualBox running, and no, I'm running Arch.

[LAUGH] Pause, I'm running Arch,

just because I wanted to make things more difficult,

but I'm almost positive that I have basic stuff working on this.

I've got Python installed if I remember correctly.

Duncan, that's cool, if you don't like the ads

don't watch the ads, but yeah, that's cool.

Enjoy your day, have a good day.

[SOUND] Sweet, so we're gonna run this as route two,

because why not, okay, so

let's make sure we've got Python, yeah.

So we've got Python 3, so

I want to setup the shared folders thing.

Shared folders, you have to use the devices menu, once this is up and

running then you can insert guest editions.

I think I've already have got guest additions installed.

So that lets me do that one, I want that folder, sure, that's fine.

Add_amount, sure.

I guess q tells us with Pac-man, let's say OK there.

So this is like Pac-man dash S virtualbox-guest-utils.

Sure, go for that, done, all right.

Auto-mount and make permanent.

Sure, I mean, we can do that.

I guess something I don't know is where those show up.

Any guesses on that?

Humanoid, we were playing with API Star,

and it started having all sorts of issues,

so we are not doing that anymore.

But we're gonna go back to API Star once we get the virtual machine working.

Network settings.

Port forwarding.

Let's not worry about those for now.

What is this ifconfig, no?

Ipconfig, no?

Ah-ha, there we go.

So I'm gonna loop back, of course,

and then do I only have it as,

I have IP6?

All right, well, let's see if we can get this to work first.

So where do I need to go for the shared folders.

[SOUND]

Is that in

Vbox?

All right, those aren't directories,

It's virtual box guest utils Open RC.

Was it that,a Pac-Man thing?

No, guess sources menu, once it's up and running, enter guests editions image,

install virtual box guest details which we did that.

Check out tutorial, that's cool.

Don't mount the Iso, that method works with many of the but not with Arch Linux.

Yeah, so we'll figure this out in a minute.

So humanoid, what our plan was, was to use this API

start package from Tom Christie which is pretty cool,

it's a neat package, and we're gonna use this to build an API,

but it is failing catastrophically on Windows.

So, With no real reason why,

it's dying through a Badly encoded thing.

So we were gonna try and get

it working on a Linux Virtual Machine, but pause is looking up stuff at the moment.

So we're gonna find out what What Pause finds out, and then we will try more.

And it's too bad, because I really

like API Stars way of working.

I wonder about doing API Star, so

let's do this while you're looking all of that up Pause.

And just send me a message when you find something.

I wanna try something new, don't wanna have a lot of downtime here y'all.

Get rid of those things again, All right, and let's install API Star again.

Let's go ahead and install that package.

And then let's install Gunicorn and

Mindheld as well And see what we can get with that.

Because we could totally just run the app, right?

Just like we would do in production.

But we can tell Unicorn to do reload and stuff, if I remember correctly.

So, let's try that out.

Error occurred.

What error occurred?

Meinheld does not like Windows?

[SOUND] Is that the problem?

With e-compliant web server, takes a measure, greenlit,

and Pico EV, can also serve through Unicorn.

Okay.

Okay.

Let's not worry about the worker class then.

So what we wanna do here is we wanna do API star.

I'll just run that, and it tells me what my things are, API star new dot

layout equals Layout equals minimal.

Okay, and so then we've got app.pi, which this has our app in it.

Okay, pause this thing to try.

Okay, let's try this out.

So mount -t vboxsf,

shared folder name, which I think was Projects.

/media/projects.

No such file or directory.

Let's check this one out again now.

Shared folder settings.

So, folder name is projects.

Yeah?

That all looks right.

We don't have any such thing as slash media.

Do I need to restart the thing?

Access a guess server

Maybe that's it.

No.

Nothing in there about Mount.

Nothing in there about VBoxSF.

All right, I'll let you keep looking, I'm gonna try and do this thing.

So what I wanna do here is I wanna do gunicorn app colon app..wsgi.

Workers equals 1, bind 8000,

head equals pid, whatever the pid is.

No module named FCNTL.

But you installed gunicorn, why?

That's the line

Install FCNTL.

We can't install that because it doesn't have one for Windows.

Okay, let's see.

Does it like lower case p, maybe?

No.

Slash media doesn't exist.

Arch, shared folders.

Shared Folders

The reasoning must be in that.

Vboxmanage?

No.

Let's just not worry about this for right now.

Alright, I'm not sure that this is

[SOUND]

Add users to a group, so

I wanna do g pass to bd-a root and

what was that group?

vboxsf.

All right,

mount-tvboxsf

projects slash

Okay, so now let's go look in here.

Check it out, there's our stuff, sweet.

[LAUGH] All right.

So now let's go into game_api.

All right,

python -m venv venv.

Read only file system.

Okay, mkdir /.virtualemvs.

Python-mbenv.virtualenvs/gameapi

gameenv.

Source virtual_emvs game_env bin activate.

Get install API star, it's installing things,

let's see if this does if anything at all.

Okay, so we have things installed,

cool, so now, not that.

How do we run this?

We just do apistar, right?

So, apistar run.

Okay.

The problem is though, now that's bound to local host 80/80 which we can't get to.

Right. So I go to 80/80 I get nothing.

So I need to rebind that to something else.

So how can I rebind that?

Settings, those aren't the settings I'm looking for.

Those aren't the settings I'm looking for.

Store configuration variables in there?

Yeah, I should.

But I don't want to at the moment.

Settings like that, static files, building websites, generating schemas,

those are all great But I need,

To have it listen on all ports.

Okay, so let's start looking at apistar/settings.

[MUSIC]

That didn't help, okay, [LAUGH] environment?

No. [MUSIC]

App.py

[MUSIC]

Path exception,

[MUSIC]

We're gonna get this running, you all.

Just a second and we're gonna have it.

[MUSIC]

Okay, let's try this,

let's try HOST=0.0.0.0.

apistar run.

[MUSIC]

Still running on that, okay.

HOST equals.

Still running on that.

[MUSIC]

There we go.

All right, so now if we try to go to 10 dot.

Man, I forgot what it was now.

IP address, okay, 10.0.2.15.

:8080, did we get anything?

[MUSIC]

No, okay.

So what was that other address that we had?

We had 10.0.2.255.

[MUSIC]

And that one's not working, okay.

Network.

Attach to NAT.

[MUSIC]

Host IP 8080.

Or no, not host IP, host port to guest port.

[MUSIC]

Okay, let's try running this like normal.

And let's try going to 8080.

Nothing.

Yeah, that one shouldn't work.

We got it, all right.

[LAUGH] Okay, so we have a thing that sort of kind of working.

So,

[MUSIC]

Let's see if we can fix this, let's see if we can change this.

Let's add a new route that does add and we'll say num1

equals by default 0, and num2 equals by default 0.

And we're going to return sum, and this will be num1 + num2.

Okay, and we'll say here, this should be of type complex.

[MUSIC]

And this here should be of type complex.

Not that it matters, but we're gonna just do that.

Okay, and so then here we'll do add, and this goes to add.

And if I look over here, it should have restarted.

But it doesn't let me do it on the complex thing, so that's fine.

[MUSIC]

Okay, run that again.

Refresh that, that gives us that, and

if we go to /add, message not found.

Is it because of that trailing slash?

Okay, so yeah, we can't add num, we can't add.

[MUSIC]

But what?

[MUSIC]

Okay, so now we'll try num1=5 and num2=9.

[MUSIC]

try num1 = complex(num1),

num2 = complex(num2),

except ValueError.

[MUSIC]

return {'message': "Those aren't

numbers!"} else: { 'message'

[MUSIC]

str(num1+ num2) }

[MUSIC]

Not exactly right, but close.

[LAUGH]

[MUSIC]

Okay,

[MUSIC]

So we have our first step, we have a thing.

Also it's kinda cool that I can code locally and

pull it up on a virtual box, that's kinda neat.

So thank you all for your help on getting that to work because that's cool.

I'm very happy to have that working.

[MUSIC]

Okay, let's look down here at the routing again.

So what we could do here is we could do,

[MUSIC]

Different routes here.

So what can we do with this?

So we can do routes, we can get a route like that.

[MUSIC]

We can use include to include a set of routes.

So, excuse me.

So we could do something like this where it was like add routes.

It's gonna be a list of routes so we can do route of,

[MUSIC]

That as GET, and that'll just do add.

[MUSIC]

Let's actually go back to these being 0.

[MUSIC]

And let's look up,

[MUSIC]

Complex.

[MUSIC]

So we pass in the real, and we pass in the imaginary, and

really I wanna try it being an int or a float.

I just wanna convert it to a number.

[MUSIC]

Okay, so let's just try this.

So if num1.isnumeric,

[MUSIC]

That's it, so all of them are numbers.

Okay, if num1.isnumeric, if '.'

in num1, num1 = float [num1]

else: num1 = int[num1]

[MUSIC]

else: num1 = 0

[MUSIC]

We're not gonna do this, def convert_num(num).

[MUSIC]

return float(num).

return int num.

[MUSIC]

return int(num),

[MUSIC]

return 0.

[MUSIC]

num1 = convert_num(num1).

[MUSIC]

Delete all of that, delete all of that, delete that.

Bring that back, that's gonna be the str(num1 + num2), all right.

[MUSIC]

Okay.

[MUSIC]

Darshan, my version of PyCharm is the paid one.

But the free one should work fine.

You shouldn't have to worry about anything weird there.

[MUSIC]

So we wanna do this where we can have num1/num2.

That would also go to GET.

Uh-huh.

So then we take that out and

we would do Include at add_routes.

And then a comma in the end.

[MUSIC]

Okay, my syntax isn't invalid.

It's running.

If we come over here and we refresh this.

Go to /add, we get 0.

If we go to /add/5/9, not found.

14, yay.

We got back the number we expected.

Okay, I don't know about you all, but that was way more work than it needed to be.

[LAUGH] But that's cool.

Okay, so I also wanted to check out docs.

So we have it working to where we can

hit our API on the virtual machine, which is cool.

Thanks again poss for helping me get that working.

We can do a URL that goes to somewhere.

And it will work, right?

So we can do /add and we get 0, because nothing came in.

We can do /add/?num1 = 10 and we should get back 10?

No?

Am I not allowed to do it that way?

Num2 = 15.

So I lost that ability.

Weird.

Why did I lose that one?

[SOUND] None.

None.

None, none, right.

Do I need to take off this slash?

No.

What if I take off this and I put in add right there?

[SOUND]

Not found.

[SOUND] I get 0.

[SOUND] Okay.

Whatever.

I don't care.

I'm gonna leave it like it was cuz it worked.

We're gonna leave that alone.

Okay, so we did that.

We get add, we get 0, right, okay.

So, let's look over here at these docs again, which this is so

cool that it lists docs just right here because how nice is that?

How can I make those, and check this out.

I can just do those and it gives me back, that's so cool.

[LAUGH] I love Tom Christie and the stuff he comes up with because

he comes up with some just absolutely amazing things.

If you all don't know who Tom Christie is, you should go and look him up.

He comes up with amazing, amazing bits of work.

Okay, so let's see what else we can do here.

So, Well so

poss, they're nice docs but they're also docs based on my endpoints.

That's what makes it so cool is it's not things I had to write.

It's stuff that Tom introspected and wrote.

So, let's do a thing here where we do Add two numbers

together and get the sum.

And together has an e in the middle of it.

If we refresh that right there, does that change anything?

[MUSIC]

No.

Darn, that would've been awesome.

Okay, so let's look now at this building websites part.

Sorry, just got a thousand pings on my phone all of a sudden.

Okay, cool.

I don't need to see any of those.

Thanks phone for interrupting me.

Okay, so now we can do templates.

So let's add a templating thing here.

So templates and then let's add a new file.

And we put in doctype.

Which I can't type apparently.

No? Not gonna do.

[SOUND] There we go.

Game API.

[SOUND] h1, high name.

Okay, so then we can take our welcome endpoint here.

Shrink this one a little bit.

So we get a name.

And we need to import templates, that comes from here.

App, Route, Templates, uh-huh.

[MUSIC]

And then he has me importing OS, but I don't see any usage of OS there so

we're not gonna worry about OS for now.

Okay, so then down here in this one,

templates, Templates.

[SOUND] name has to be a str, has to be a string.

And we're gonna do index = templates.get_template.

We wanna get index.html, or return index.render, name=name.

[SOUND] And we already have that route there for welcome.

And then we need to add our settings, so let's do settings, is a dictionary.

TEMPLATES is also a dictionary.

DIRS is a list with templates in it,

and then we have to specify our settings inside there.

[SOUND] Okay, let's make sure this is all running.

No?

[MUSIC]

Unresolved reference to templates.

[MUSIC]

What?

[MUSIC]

I'm gonna guess it's Template.

[MUSIC]

What's up, Tom?

What's up, man?

Why do I keep finding things here that aren't working?

[MUSIC]

Can you define it all in here?

Templates.

[MUSIC]

All right, let's do a thing that I normally hate doing.

from apistar import star.

[SOUND] I hate doing that.

[MUSIC]

Okay, let's try running that.

Templates is not defined.

Okay.

So let's go into Python.

from apistar import star.

Yeah, that didn't work.

from apistar.templating import Templates.

Okay, so that one works.

So let's just import that manually.

from apistar.templating import Templates.

And t comes after s, so we'll put that there.

And then put that there.

Okay.

And then let's run that again.

Okay.

And then if I go to here, I get hi name!

And if I say name equals Kenneth, I get nothing.

If I go to that, I get message not found.

But where did you get the username from?

Did I do my template wrong?

I did.

Okay.

Close that.

There's the name.

All right, cool.

[LAUGH] So we have something.

Something is coming out, okay.

So, cool.

We've gotta thing.

We're slowly working our way through this.

Now I wanna see what this thing is here.

So you can also use the template component to inject a single template instance

as a view argument.

Def hello user name string index template.

So, that would be here.

And then we do index.render,

that will attempt to locate index.html based on the argument name of index.

I see.

That's kinda cool.

So let's try that.

So here we can do index is a template.

And we just return index.render.

So we should still get the same thing.

We do.

Let's change this just to make sure that it's working.

Welcome to the API.

Boom! Okay.

That's pretty cool.

Good job there, Tom.

We had an issue but we gotta thing.

It's okay.

All right, so now let's try one more thing here just to make sure it's working.

So we'll make a directory called Static and

then inside Static, we'll make a new directory called, CSS.

And inside there we'll make a new file, which we'll call games.css.

And we'll just do body, background color.

Seagreen, and we'll do color as bisque

just to do absolutely horrible things

that nobody should ever really see.

Okay, and then here we say statics, and we say dir,

and then we say static, cuz I don't know why that

is duplicated there, or plural rather.

Okay, then from statics we also want to call serve static.

I'm wondering if that's actually needed cuz I have a feeling that the static

routes here might be working.

Let's test that real quick.

What would we do up here?

We'd do link href

equals static.

Css games.css.

url equals stylesheet.

And that works. I don't have add anything.

So that means I can come over here and take out that part.

So that still works.

All right, that looks horrible, but that's fine.

It's okay if it looks horrible.

We can make it look nicer later if we really want to, okay.

[SOUND] I kind of feel bad we're at 13 minutes left.

It's kind of weird to start something at this point.

But, any questions?

Anything weird for everybody?

Anything that you all are confused about or

have questions about with all of this, let me know.

Tell me what you're thinking?

No pause, no, no pause,

those are just me getting real lucky, just really really lucky.

So I'm just kinda playing around with this stuff.

So my plan, there's a website called

Board Game Geek, which is kind of a horrible website.

Like it's cool as far as he can go pop open a game and

find out a bunch of data about it.

That's cool.

It's full of comments I don't care about,

rankings I don't care about, stuff like that.

My thought was that we'll build a little API off of API Sta.

That we can add a new game to the records and we can

search for games, we can pull a game out.

So, that's my plan.

I don't believe that plan is going to necessarily work.

And that plan is definitely not going to work today.

We're not gonna do all that today.

But then I was also thinking about trying out vue.js with that.

Cause vue.js seems kinda cool.

I haven't gotten to play with vue.js, but it seems kinda neat.

So, that'll come later.

First we'll get the basic thing working.

I was gonna do this all with Flask.

And then it was like well why do it with flask,

I'm just gonna do it with API star, cuz API star seems cool.

And API star is cool when it works.

And so far it's worked fairly well right?

So I could use Kenneth Wright's tab lib as a way of doing the data sets

I don' know if I want to do that.

I mean it's really cool, but

I mean, maybe.

Let's try it, let's see what we can do here.

Is there a way to just throw stuff in there?

See the filter is really cool.

I really like the filter.

That's basically what I want.

That's basically it.

Okay.

So, let's make a new file, and

let's call this game schema.

It's not exactly right for what I wanna do, but we'll call it that.

Well, we've got about ten minutes left.

If y'all have any questions, now's the time to ask them.

Toss your questions into chat and I will answer them before we wrap up for the day.

And next week, we'll do some of this stuff for real.

Tom was saying that there's some issues with databases and schemas.

So, I'm gonna try to stay away from that but we'll do what we can here.

So, let's import tablib.

And let's make a new thing here which is games

is tablib.Dataset, games.headers is,

and I wanna have, Name, Designer,

Player count Yep, player count.

Scores.

[MUSIC]

Let's not worry about scores for now.

Scores seems like too much work.

Okay, so then we

wanna do def read, and

with open('games.json')

as f:,

[MUSIC]

f.read,

[MUSIC]

data = f.read,

[MUSIC]

return data, there's far better ways to doing that, but whatever.

[MUSIC]

And then that would be where we'd do that.

So let's say, def write, with open('games.json',

[MUSIC]

write,

[MUSIC]

I always forget what my arguments are for this.

That's all I want, I just want w, cuz I don't want binary.

I don't wanna append, I just wanna write the whole thing, okay.

So 'w') as f:, f.write(games.json)

[MUSIC]

Okay.

[MUSIC]

So,

[MUSIC]

I should,

[MUSIC]

Be able to,

[MUSIC]

add_game, and we're gonna take name, designer,

[MUSIC]

player_count, let's actually take one more, which is duration.

[MUSIC]

Okay, so now take that off, take that off, take that off.

And I want to add the new thing.

Is there something in here about schemas, yeah.

[MUSIC]

Okay, so then we can make a schema here.

So let's go ahead and do that here, too.

from apistar import schema,

class GameSchema(schema.Object):,

properties = {'name', schema.String,

[MUSIC]

'designer', schema.String,

[MUSIC]

'player_count',

[MUSIC]

schema.

[MUSIC]

Integer,

[MUSIC]

And 'duration', schema.Integer.

[MUSIC]

And then here,

[MUSIC]

from game_schema import GameSchema.

[MUSIC]

So here we would do game: GameSchema.

[MUSIC]

And let's actually import games here, as well.

[MUSIC]

And,

[MUSIC]

Let's do,

[MUSIC]

For now, let's just do this, so message,

[MUSIC]

game, cuz I don't know what this will actually do.

[MUSIC]

So we don't care about any of those, we don't care about that.

We wanna do add, and this'll be a POST, and this would go to add_game.

[MUSIC]

And then let's open up,

[MUSIC]

Postman,

[MUSIC]

And we don't wanna go to that, we wanna go to,

[MUSIC]

localhost:8080, let's see if that works, could not get any response.

Turn off that,

[MUSIC]

Delete that,

[MUSIC]

No module named 'tablib', but

I installed tablib, didn't I?

There's tablib.

[MUSIC]

Did I not install tablib?

[MUSIC]

I didn't install tablib here, [SOUND] that's the thing I gotta do.

I don't care about installing it there, I need to install it here.

Which means that I could probably do this.

I could probably change this, nope.

Add Local, and if I went into here,

and here, and here, and here,

[MUSIC]

Would that work?

[MUSIC]

Nope, darn, okay, now let's try it.

[MUSIC]

I need more data about your thing here.

[MUSIC]

Sweet, so there's that thing, okay.

So now if I try to go to add, Method not allowed.

Let's go to POST, let's look at our Body.

And we're gonna say that the name of the game is Pictomania.

And the designer of

the game is Vlada Chavdl.

And the player-count is 6,

and the duration is 45,

and we Send that.

Player_count, Must be a valid number, Duration, Must be valid number.

Are those not numbers?

[MUSIC]

Form data.

[MUSIC]

Raw, JSON, name,

[MUSIC]

'Pictomania', 'designer',

'Vlada Chavdl',

[MUSIC]

'player_count', '5',

'duration', '45'.

[MUSIC]

Sweet, and we got one back, okay.

Now that didn't save it to the database.

We didn't do anything like that, but we definitely got one back.

So it generated one from the schema and gave us one back, that's really cool.

Okay, we're at noon, I'm stopping here.

We will do more later, but I'm gonna answer your questions.

Darshan asks, what book is best to learn Django from scratch?

I don't think you actually need a book to learn Django from scratch.

Assuming you know Python, which if you don't know Python,

don't try to learn Django, go learn Python.

But the Django tutorial and the Django Girls tutorial,

djangogirls.org and docs.djangoproject.com.

I may have those URLs wrong, but I think those are right.

Follow those tutorials, and you'll have a pretty good grasp of Django.

At that point, go start building something.

Just build whatever thing you wanna build.

Build five different things that you wanna build.

And then start looking for books,

blog posts, tutorials that fill in the questions that you have.

If you're a Treehouse student, I think the Treehouse content is pretty good for

Django.

But I'm biased, very biased.

And then once you're a little further on, Two Scoops of Django is an amazing book.

Especially once you've built two or three sites, and

you're feeling pretty comfortable.

And as pos brings up, Hello Web App is also a good book, and,

[MUSIC]

Python Crash Course has some really good Django stuff in it, and just Python stuff.

If you just wanna learn Python and stuff like that, this is also an amazing book.

So try that one out, and Ammar Yassir asks what we're building today.

Go back and watch the video, we had a whole bunch of trouble.

[LAUGH] So we're using a project called apistar to build an API.

And it just bombed catastrophically on my Windows.

Which I'm gonna have to talk to the creator of it to find out what's

going on there.

But we got it running in a virtual machine, thanks to pos's help.

And so it's working now, so it's cool.

So what we're gonna build, we'll start building more of this next week,

is we're building just a simple little API that we can send board games into.

And search for board games, and pull them back out.

So that's all we're gonna do there, but that's my plan at least.

So we'll find out, we'll find out if that all works.

But it is 12:04 PM, it's after the noon,

[MUSIC]

Bell thing, so I'm gonna call it quits for today.

But thank you, all, for watching, glad to be back.

I missed last week, I was at PyCon, which was amazing and awesome.

If you are in any sort of position to travel to PyCon next year,

it's gonna be in Cleveland, Ohio.

It's gonna be amazing, I'll be there.

I'd love to see all of you there, but yeah, check out PyCon.

All the videos are online if you wanna watch them.

Including a three-hour tutorial from me if you want to learn about Django admin.

So go to YouTube, search for PyCon 2017, go watch videos.

There's hundreds of them, and they're amazing.

So thank you very much for watching, and I'll see you all next week.

Have a great weekend.
