1
00:00:00,120 --> 00:00:03,460
It wouldn't do us much good to build this
if we didn't have users that could,

2
00:00:03,460 --> 00:00:04,980
you know, use it.

3
00:00:04,980 --> 00:00:08,300
Social apps kind of fall apart when
there's no one to be social with.

4
00:00:08,300 --> 00:00:11,750
One way to make it social is to use third
party log ins, and let people sign up and

5
00:00:11,750 --> 00:00:13,750
log in with Twitter or Facebook.

6
00:00:13,750 --> 00:00:14,830
It's always seemed weird to me,

7
00:00:14,830 --> 00:00:18,590
to be able to log in to a social site with
some other social site's credentials.

8
00:00:18,590 --> 00:00:22,770
And, that doesn't help us learn how to
model these things ourselves, does it?

9
00:00:22,770 --> 00:00:25,190
That's why I'm going to show you a
different way.

10
00:00:25,190 --> 00:00:27,330
All right.
So the first thing we need to do, is,

11
00:00:27,330 --> 00:00:30,488
we need to make our models.py file.

12
00:00:30,488 --> 00:00:35,820
So we'll go to File > New File, and we'll
call it models.py.

13
00:00:35,820 --> 00:00:39,920
Now, inside of here, just as we did the
databases course,

14
00:00:39,920 --> 00:00:45,250
we want to import everything from peewee,
[SOUND] so from peewee import star.

15
00:00:45,250 --> 00:00:49,580
And, our user model is gonna be pretty
simple, really.

16
00:00:50,590 --> 00:00:51,260
Let's see.

17
00:00:51,260 --> 00:00:53,190
So, class user, and it's gonna be a model.

18
00:00:54,690 --> 00:00:56,890
So we're gonna give them, a username.

19
00:00:56,890 --> 00:00:59,600
We don't really have to, I mean, most of
what we're gonna build,

20
00:00:59,600 --> 00:01:03,160
we could just use the ID, which is a field
that's automatically created and

21
00:01:03,160 --> 00:01:05,510
it auto-increments, so the first one gets
number one,

22
00:01:05,510 --> 00:01:07,660
the next one gets number two and so on.

23
00:01:07,660 --> 00:01:11,830
But I like having a username to put into
URLs instead of giving them like,

24
00:01:11,830 --> 00:01:14,560
you're following user number five, but it
doesn't really matter.

25
00:01:14,560 --> 00:01:16,050
It's kinda your choice.

26
00:01:16,050 --> 00:01:20,765
So we'll say username, which is a
CharField, [SOUND] and

27
00:01:20,765 --> 00:01:23,821
we wanna make sure these are unique.

28
00:01:23,821 --> 00:01:26,996
We don't want them to be able to have two
people with the same username

29
00:01:26,996 --> 00:01:28,990
cuz we wanna look them up by that
username.

30
00:01:30,020 --> 00:01:33,580
And then we'll do email which is also a
CharField,

31
00:01:33,580 --> 00:01:37,070
not a chair field, so watch out for that
typo.

32
00:01:38,390 --> 00:01:41,540
Again, we wanna make this one unique
because we only wanna have

33
00:01:41,540 --> 00:01:42,950
one account per email address.

34
00:01:42,950 --> 00:01:45,845
We don't want somebody to be able to have
five different accounts with the same

35
00:01:45,845 --> 00:01:47,090
email address.

36
00:01:47,090 --> 00:01:49,290
They need to store a password.

37
00:01:49,290 --> 00:01:51,220
And this is also going to be a CharField.

38
00:01:51,220 --> 00:01:54,810
And we're gonna set a max length on this
one of 100.

39
00:01:54,810 --> 00:01:58,710
The, hashing library that we use produces
hashes of around, like,

40
00:01:58,710 --> 00:01:59,550
60 characters or so.

41
00:01:59,550 --> 00:02:03,280
But we want to have some wiggle room just
in case something changes.

42
00:02:03,280 --> 00:02:07,220
Maybe we change hashing algorithms later
or whatever.

43
00:02:07,220 --> 00:02:09,112
And then I wanna hold on to a couple of
things.

44
00:02:09,112 --> 00:02:12,779
I wanna hold on to when they joined,
[SOUND] and

45
00:02:12,779 --> 00:02:17,808
we'll set the default on this to
datetime.datetime.now.

46
00:02:17,808 --> 00:02:18,900
Oops.

47
00:02:18,900 --> 00:02:22,143
No parenthesis on that, remember we don't
want to put a parenthesis or

48
00:02:22,143 --> 00:02:24,314
else it'll be set to whenever the script
runs.

49
00:02:24,314 --> 00:02:27,584
Not whenever the model's actually created.

50
00:02:27,584 --> 00:02:32,485
[SOUND] And then we'll hold onto a field
called is_admin,

51
00:02:32,485 --> 00:02:37,295
[SOUND] and this is really more of setting
you up for later.

52
00:02:37,295 --> 00:02:37,870
Oops, sorry.

53
00:02:37,870 --> 00:02:38,600
That should be false.

54
00:02:38,600 --> 00:02:43,490
This is really more of setting you up for
later to where you're finished with

55
00:02:43,490 --> 00:02:46,420
this course, you wanna expand this, you
wanna go a little farther.

56
00:02:46,420 --> 00:02:50,820
And maybe, if the user's an admin, they
get to see some special UI abilities.

57
00:02:50,820 --> 00:02:54,700
Or maybe they get a special form where
they can talk or whatever.

58
00:02:54,700 --> 00:02:57,020
Since we're using this datetime right
here,

59
00:02:58,140 --> 00:03:01,050
we are going to want to import datetime,
so

60
00:03:01,050 --> 00:03:05,910
we'll say import datetime, and we should
probably go ahead and set up our database.

61
00:03:06,910 --> 00:03:11,300
I'm gonna use SQLite again, just as we did
in the databases course.

62
00:03:11,300 --> 00:03:15,780
But if you want to use MySQL or Postgres,
that's fine as well.

63
00:03:15,780 --> 00:03:19,290
And since this is going to be just the
single database that we're gonna talk

64
00:03:19,290 --> 00:03:22,410
about in multiple locations, I'm gonna put
it in all caps.

65
00:03:22,410 --> 00:03:26,261
Now in Python, putting it in all caps
doesn't make it a constant, but

66
00:03:26,261 --> 00:03:29,546
it tells people that you're wanting this
to be a constant.

67
00:03:29,546 --> 00:03:37,522
So database and let's just say social.db.

68
00:03:37,522 --> 00:03:39,260
If you want to use a different name,
that's fine.

69
00:03:39,260 --> 00:03:43,140
It seems like I used just these simple
little names.

70
00:03:43,140 --> 00:03:44,920
And then, let's make this a little bigger.

71
00:03:44,920 --> 00:03:47,080
There we go.

72
00:03:47,080 --> 00:03:50,340
And then down at the bottom of course, now
that we've made this model,

73
00:03:50,340 --> 00:03:52,710
we have to set our class meta.

74
00:03:52,710 --> 00:03:55,240
And we have to say that database is equal
to DATABASE,

75
00:03:55,240 --> 00:03:58,415
all caps, down there at the bottom.

76
00:03:58,415 --> 00:04:02,400
And then, if we were going to build a
view, which we're not going to, but

77
00:04:02,400 --> 00:04:03,360
you can if you want to.

78
00:04:04,380 --> 00:04:06,370
Build a view where we list all the users.

79
00:04:06,370 --> 00:04:10,480
So like, I wanna go find, you know, my
friend Jim, or my friend Ashley.

80
00:04:10,480 --> 00:04:16,387
We're gonna set how we would order them
and we're gonna order them by joined at.

81
00:04:16,387 --> 00:04:20,031
[SOUND] But with a minus sign at the
beginning of it.

82
00:04:20,031 --> 00:04:23,420
And so that tells order by to do this
descending.

83
00:04:23,420 --> 00:04:26,771
So our newest users are going to be sorted
at the top.

84
00:04:26,771 --> 00:04:30,779
So, you'll get to see people who just
signed up, and then when you get to

85
00:04:30,779 --> 00:04:34,478
the bottom, you'll see the people who've
been here for a while.

86
00:04:34,478 --> 00:04:36,330
All right, so I'm gonna save this.

87
00:04:36,330 --> 00:04:40,190
I'm not actually gonna create the,
database file right now.

88
00:04:40,190 --> 00:04:42,790
I'm not gonna run like initialize or
anything.

89
00:04:42,790 --> 00:04:45,210
We'll do that later on when we have a
couple more things built.

90
00:04:46,660 --> 00:04:49,850
Our user model is nice and simple for now.

91
00:04:49,850 --> 00:04:52,170
I'm sure that it'll change before we're
done with this course.

92
00:04:52,170 --> 00:04:55,332
In fact, in the next video, we're going to
add some functionality to our

93
00:04:55,332 --> 00:04:57,680
user model so that we'll be able to have
users sign in.
