1
00:00:00,450 --> 00:00:01,070
In order for

2
00:00:01,070 --> 00:00:04,570
my Django project to run correctly on
PythonAnywhere, I need two things.

3
00:00:04,570 --> 00:00:08,830
I need a list of all the requirements
that the project needs and

4
00:00:08,830 --> 00:00:14,630
I need a deploy specific WSGI or
wsgi file, and this is

5
00:00:14,630 --> 00:00:18,678
a file that will tell the PythonAnywhere
server how to run the project.

6
00:00:18,678 --> 00:00:21,618
So, I'm gonna start by making sure
that the correct packages for

7
00:00:21,618 --> 00:00:23,230
my project are installed locally.

8
00:00:23,230 --> 00:00:27,988
So, I have a new virtual environment here
and I'm gonna install the package of

9
00:00:27,988 --> 00:00:32,330
this clean fresh brand new, so
that I know I have the newest best stuff.

10
00:00:33,730 --> 00:00:38,153
So, first off,
I'm gonna run pip install django==1.9.4,

11
00:00:38,153 --> 00:00:40,297
although really 1.9 is fine.

12
00:00:43,010 --> 00:00:47,299
And that's gonna make sure that I have the
same version of Django installed that was

13
00:00:47,299 --> 00:00:50,560
used to create the project,
in the course where we created it.

14
00:00:50,560 --> 00:00:55,460
I also wanna make sure that I have
the WhiteNoise package installed,

15
00:00:55,460 --> 00:00:57,400
which is used for serving static assets.

16
00:00:57,400 --> 00:01:02,800
So to install that I'll do pip install
whitenoise, and I want a specific version,

17
00:01:02,800 --> 00:01:06,442
just because this is the one
that's currently around.

18
00:01:06,442 --> 00:01:09,800
And it's always a good idea
to pin your deployments, or

19
00:01:09,800 --> 00:01:12,950
to specify a Python package version for
each thing.

20
00:01:14,590 --> 00:01:18,550
Now, WhiteNoise is the recommended package
for serving static assets in Python.

21
00:01:18,550 --> 00:01:22,770
It can, and will, serve your assets
compressed to a smaller size.

22
00:01:22,770 --> 00:01:27,450
And it will set the correct caching
headers, both of these things combined

23
00:01:27,450 --> 00:01:31,905
caching so that the files get held
onto by the browser and compressions,

24
00:01:31,905 --> 00:01:37,140
although smaller, will make things
a lot nicer for your users, so yee.

25
00:01:37,140 --> 00:01:42,551
Now I'm gonna save both of these things
into a file called requirements.txt,

26
00:01:42,551 --> 00:01:47,087
by doing pip freeze, and
let's just look at what pip freeze does.

27
00:01:47,087 --> 00:01:52,090
So that tells me that Django 1.9 and
WhiteNoise are installed.

28
00:01:52,090 --> 00:01:57,138
If I do pip freeze > requirements.txt,
then now,

29
00:01:57,138 --> 00:02:02,528
if I do an ls,
you can see I have requirements.txt, and

30
00:02:02,528 --> 00:02:10,130
if I cut that, you can see it has the same
output that pip freeze gave me up here.

31
00:02:11,160 --> 00:02:13,400
This is just a quick way of getting
those requirements into a file.

32
00:02:14,610 --> 00:02:20,268
Okay, now though,
I need the deploy wsgi file and

33
00:02:20,268 --> 00:02:27,154
I'm gonna do that by editing
the file in a plain text editor.

34
00:02:27,154 --> 00:02:30,871
Now on this machine I'm
gonna be using Atom, but

35
00:02:30,871 --> 00:02:34,960
you can do whatever text
editor you would like to use.

36
00:02:37,420 --> 00:02:41,860
And before I go edit any files,
I'm gonna copy the file.

37
00:02:41,860 --> 00:02:45,262
So if I go into djangoal/djangoal/,

38
00:02:45,262 --> 00:02:50,928
there is a file in here that is wsgi.py,
I'm gonna copy that, so

39
00:02:50,928 --> 00:02:56,020
I'm gonna cp wsgi.py and
I'm gonna call it deploy.py.

40
00:02:56,020 --> 00:02:58,920
This is my deployment wsgi file.

41
00:02:58,920 --> 00:03:04,099
All right, so this file,
djangoal > djangoal > deploy.wsgi,

42
00:03:04,099 --> 00:03:09,150
this is the file that I'm gonna edit for
the server.

43
00:03:09,150 --> 00:03:11,800
So in order for
the project to run on PythonAnywhere,

44
00:03:11,800 --> 00:03:15,628
I need to adjust the system path to
include the full path to the code.

45
00:03:15,628 --> 00:03:21,265
So, here I need to import sys,

46
00:03:21,265 --> 00:03:25,620
S-Y-S, and then I'm going to set
a new variable here called path.

47
00:03:25,620 --> 00:03:32,750
And I'm gonna say path = /home, and
then I'm gonna put in my user name,

48
00:03:32,750 --> 00:03:38,120
so I'm gonna put in kennethtreehouse,
and then I put in deploying_django,

49
00:03:38,120 --> 00:03:41,790
because that's the name of the project,
and then djangogoal because

50
00:03:43,170 --> 00:03:47,130
this is the Git checkout and
then this is the project name.

51
00:03:48,820 --> 00:03:54,292
And then I'm gonna say
if path not in sys.path,

52
00:03:54,292 --> 00:03:57,919
sys.path.append(path).

53
00:03:57,919 --> 00:04:03,270
So sys.path,
is all the locations that Python looks for

54
00:04:03,270 --> 00:04:08,460
code, and so I'm checking to make sure
that the current one is in there and

55
00:04:08,460 --> 00:04:10,310
if it's not then to make sure and add it.

56
00:04:10,310 --> 00:04:14,575
I also need to add the lines that
will make the project use WhiteNoise.

57
00:04:15,630 --> 00:04:19,838
So the first thing I need to do for
that is up here and here,

58
00:04:19,838 --> 00:04:22,430
I need to import WhiteNoise.

59
00:04:22,430 --> 00:04:27,789
So from whitenoise.django
import DjangoWhiteNoise,

60
00:04:27,789 --> 00:04:31,917
and I'm gonna add a line
here at the bottom,

61
00:04:31,917 --> 00:04:37,860
I already have this application
= get_wsgi_application.

62
00:04:37,860 --> 00:04:44,298
I'm gonna add a new one here, application
= DjangoWhiteNoise(application).

63
00:04:44,298 --> 00:04:49,401
So what we're doing is,
I'm re-wrapping the application variable

64
00:04:49,401 --> 00:04:54,610
with this new wsgi application,
named DjangoWhiteNoise.

65
00:04:54,610 --> 00:04:58,900
Now, though I have all the files that
PythonAnywhere needs to deploy the app.

66
00:04:58,900 --> 00:05:02,780
So, I wanna get this new
code into PythonAnywhere.

67
00:05:02,780 --> 00:05:06,090
So, the first thing that I'm gonna do is
I'm gonna send this to GitHub, all right?

68
00:05:06,090 --> 00:05:07,711
So I'm gonna clear this.

69
00:05:07,711 --> 00:05:12,350
And if I do a git status, I can see that
I have these two files that aren't there.

70
00:05:12,350 --> 00:05:14,910
So, let me get back out here.

71
00:05:16,510 --> 00:05:19,950
Okay, so
I'm gonna add the requirements file and

72
00:05:19,950 --> 00:05:22,978
I'm gonna add the,
actually I'm just gonna add dot.

73
00:05:24,250 --> 00:05:28,727
So now if I do git status,
both those files are in there,

74
00:05:28,727 --> 00:05:32,062
I'm gonna do a commit and I'm gonna say,

75
00:05:32,062 --> 00:05:35,890
Add the files PythonAnywhere
needs to deploy.

76
00:05:38,763 --> 00:05:45,189
And then I'm gonna do
a git push origin master.

77
00:05:49,779 --> 00:05:52,145
Okay, now once that's pushed,

78
00:05:52,145 --> 00:05:56,799
I can come back over here to
PythonAnywhere, to my console here.

79
00:05:56,799 --> 00:05:59,205
And I can do and git pull.

80
00:06:14,645 --> 00:06:20,090
And if I do an ls here, I should see my
requirements file, and there it is, great.

81
00:06:20,090 --> 00:06:27,002
So now I can actually do a,
I move that up a little bit,

82
00:06:27,002 --> 00:06:31,970
I can install my packages by doing
pip install -r requirements.txt.

83
00:06:31,970 --> 00:06:37,510
Make sure you use that -r, that tells
pip to read the requirements.txt.

84
00:06:37,510 --> 00:06:41,770
And once these two packages are installed,
Django and WhiteNoise,

85
00:06:41,770 --> 00:06:43,910
I'll have everything
that I need installed and

86
00:06:43,910 --> 00:06:47,075
ready to go to actually run
the app on PythonAnywhere.

87
00:06:47,075 --> 00:06:51,217
In the next video, I'm gonna wire
the PythonAnywhere web server up

88
00:06:51,217 --> 00:06:55,299
to the project and I should be able
to see the project running live.
