1
00:00:00,420 --> 00:00:05,240
Okay, so let's build this user_stream.html
template, and

2
00:00:05,240 --> 00:00:07,790
then check this whole thing out, see how
it works.

3
00:00:07,790 --> 00:00:14,234
So let's go back to templates, make a new
file, user_stream.html.

4
00:00:15,820 --> 00:00:18,570
And, so this one's a little bit different.

5
00:00:18,570 --> 00:00:19,950
You may not have seen us do,

6
00:00:19,950 --> 00:00:22,110
actually you've not seen me do something
like this yet.

7
00:00:23,180 --> 00:00:28,261
So it's going to extend stream.html, not
layout.

8
00:00:28,261 --> 00:00:31,450
I mean, ultimately it extends layout
because stream extends layout.

9
00:00:32,570 --> 00:00:33,800
But not on its own.

10
00:00:35,350 --> 00:00:36,660
And block content.

11
00:00:36,660 --> 00:00:38,210
So, I'm gonna add new things to the block.

12
00:00:39,650 --> 00:00:41,925
And we're gonna add in some statistics.

13
00:00:41,925 --> 00:00:50,113
[SOUND] And class equals grid-25.

14
00:00:50,113 --> 00:00:51,490
And.

15
00:00:53,730 --> 00:00:56,300
H one is user.username.

16
00:00:57,440 --> 00:01:04,861
And then we're gonna do div class equals
grid-50.

17
00:01:04,861 --> 00:01:07,611
Div class equals grid-33.

18
00:01:10,690 --> 00:01:12,830
H5 and we're gonna say posts.

19
00:01:14,880 --> 00:01:20,495
So I'm gonna do a P and we'll say
user.post.count cuz we wanna.

20
00:01:20,495 --> 00:01:24,415
Count out the number of posts that they
have, and I actually wanna take this.

21
00:01:24,415 --> 00:01:26,015
I'm gonna make two more copies of it.

22
00:01:26,015 --> 00:01:31,985
And we're gonna change the second one here
from posts to followers.

23
00:01:33,515 --> 00:01:34,795
We don't have followers yet.

24
00:01:34,795 --> 00:01:36,375
So we're can just take that out.

25
00:01:36,375 --> 00:01:37,345
And we'll just say zero.

26
00:01:37,345 --> 00:01:41,670
And then here, I wanna change this to
following.

27
00:01:41,670 --> 00:01:43,800
And we don't have those yet either.

28
00:01:43,800 --> 00:01:47,370
So that's also going to be 0.

29
00:01:47,370 --> 00:01:49,800
All right, and then down here below, our
div-50,

30
00:01:49,800 --> 00:01:53,900
we're gonna do another div class equals
grid-25.

31
00:01:53,900 --> 00:01:59,430
And that's it for now cuz this is where
our follow button's gonna go.

32
00:02:00,740 --> 00:02:02,850
We'll put in note, follow unfollow button.

33
00:02:02,850 --> 00:02:06,080
That's what's gonna go there.

34
00:02:06,080 --> 00:02:09,310
So now we've got all this stuff inside of
our block.

35
00:02:09,310 --> 00:02:12,410
I wanna come down here and I wanna call
super.

36
00:02:13,590 --> 00:02:15,090
And then, endblock.

37
00:02:15,090 --> 00:02:18,250
So you remember, if you did Flask Basics,
when we call super,

38
00:02:18,250 --> 00:02:22,340
it brings in the content of the block from
the parent template.

39
00:02:22,340 --> 00:02:25,110
So, stream.html is our parent template.

40
00:02:26,870 --> 00:02:31,330
Block content, the content here, is all
this stuff from the stream.

41
00:02:31,330 --> 00:02:32,300
So, awesome.

42
00:02:32,300 --> 00:02:35,610
And you know what, if I look at this, we
don't use the user anywhere.

43
00:02:35,610 --> 00:02:38,582
But I bet we're gonna use the user up
here.

44
00:02:38,582 --> 00:02:41,210
Actually we are, we're using the user
here.

45
00:02:41,210 --> 00:02:43,560
So, okay.

46
00:02:43,560 --> 00:02:44,530
Let's try this out.

47
00:02:44,530 --> 00:02:45,330
Let's make a new post.

48
00:02:46,810 --> 00:02:49,319
Recording my course.

49
00:02:49,319 --> 00:02:53,490
Can't believe we've done so much.

50
00:02:53,490 --> 00:02:55,820
I want a couple more Os in there.

51
00:02:56,820 --> 00:02:57,660
All right.
Let's hit Post.

52
00:02:59,640 --> 00:03:00,530
Oh, no such table.

53
00:03:00,530 --> 00:03:01,510
Post.

54
00:03:01,510 --> 00:03:02,340
Why is that?

55
00:03:02,340 --> 00:03:04,937
Here in models.py, in our initialize.

56
00:03:04,937 --> 00:03:05,910
.

57
00:03:05,910 --> 00:03:08,620
We forgot to initialize post.

58
00:03:09,820 --> 00:03:11,280
So we need to do that.

59
00:03:11,280 --> 00:03:16,050
The second one is a little harder to find
and it's over here in app.py.

60
00:03:16,050 --> 00:03:19,190
So we have this try and pass.

61
00:03:19,190 --> 00:03:24,260
And it's weird because I expected this to
just go through, but

62
00:03:24,260 --> 00:03:29,380
it seemed like if it created one that
didn't work, and it hit that value error,

63
00:03:29,380 --> 00:03:32,760
our database would be locked, and we
couldn't do anything with our database.

64
00:03:32,760 --> 00:03:34,560
So, we need to add one thing here.

65
00:03:34,560 --> 00:03:42,050
So, we're gonna say with
models.database.transaction.

66
00:03:42,050 --> 00:03:47,270
Then we're gonna take all of this, tab
that in.

67
00:03:47,270 --> 00:03:48,140
So what does this do?

68
00:03:48,140 --> 00:03:54,630
Well, so a transaction says try this thing
out, if it works, awesome.

69
00:03:54,630 --> 00:03:55,650
Keep going.

70
00:03:55,650 --> 00:03:59,430
If it doesn't work, remove what everything
you just did.

71
00:03:59,430 --> 00:04:02,430
So, maybe our user gets like halfway
created.

72
00:04:02,430 --> 00:04:05,350
We don't want that to happen, we want that
to just come right back out.

73
00:04:05,350 --> 00:04:08,980
Now it'd probably make more sense now that
I'm looking at this, for

74
00:04:08,980 --> 00:04:14,370
us to do it in our create thing.

75
00:04:14,370 --> 00:04:15,410
So let's do it there.

76
00:04:15,410 --> 00:04:16,610
Let's actually take this out.

77
00:04:18,500 --> 00:04:23,420
Oh, the joys of designing while you're
coding.

78
00:04:23,420 --> 00:04:25,870
And let's do it here.

79
00:04:25,870 --> 00:04:32,141
So we'll say with DATABASE.transaction().

80
00:04:32,141 --> 00:04:35,410
And if that fails, if it raises this
integrity error, whatever, that's fine,

81
00:04:35,410 --> 00:04:39,750
we'll still return the value error, but
try doing this.

82
00:04:39,750 --> 00:04:42,930
So now, let's check and see.

83
00:04:44,290 --> 00:04:45,240
I'm logged in.

84
00:04:46,440 --> 00:04:47,830
Sorry, that was a test thing I did.

85
00:04:47,830 --> 00:04:50,280
Let's hit Create New Post.

86
00:04:50,280 --> 00:04:51,810
And let's see if we can post.

87
00:04:51,810 --> 00:04:56,940
So let's do recording my second Flask
course.

88
00:04:56,940 --> 00:05:00,460
Can't believe how much we've learned.

89
00:05:01,880 --> 00:05:03,320
Let's hit post.

90
00:05:03,320 --> 00:05:03,850
Sweet.

91
00:05:03,850 --> 00:05:05,600
Took us to the homepage.

92
00:05:05,600 --> 00:05:07,320
And here is this.

93
00:05:07,320 --> 00:05:09,280
So now if I was to click on my name.

94
00:05:10,580 --> 00:05:12,860
Then it goes to my stream page.

95
00:05:13,920 --> 00:05:15,750
I've made one post.

96
00:05:15,750 --> 00:05:16,560
There's my name.

97
00:05:16,560 --> 00:05:18,650
There's all that stuff.

98
00:05:18,650 --> 00:05:19,320
If we hit all.

99
00:05:20,380 --> 00:05:21,880
Goes to there.

100
00:05:21,880 --> 00:05:27,320
And I think we can actually go ahead and
add in one more link to our layout.

101
00:05:28,450 --> 00:05:30,670
So let's go over here and look at our
layout.

102
00:05:32,070 --> 00:05:38,590
And what we wanna do is we want to add a
link to a page for our own stream.

103
00:05:39,740 --> 00:05:42,730
So let's go here, a href.

104
00:05:42,730 --> 00:05:45,290
And we do URL for and we wanna say stream.

105
00:05:45,290 --> 00:05:53,562
And we wanna say username equals
current_user.username.

106
00:05:53,562 --> 00:05:54,720
And we'll say here,

107
00:05:54,720 --> 00:05:59,990
we'll say following because this is the
stuff that you're following, right.

108
00:05:59,990 --> 00:06:03,220
Let's refresh this and we can go to
Following.

109
00:06:03,220 --> 00:06:04,548
We can go to All.

110
00:06:04,548 --> 00:06:06,263
Okay.

111
00:06:06,263 --> 00:06:07,978
Cool.

112
00:06:07,978 --> 00:06:10,480
So same as me clicking my own name, but

113
00:06:10,480 --> 00:06:14,720
when there's other users, me clicking my
own name won't do anything there.

114
00:06:16,620 --> 00:06:17,220
Great.

115
00:06:17,220 --> 00:06:18,430
Once we get the social things in,

116
00:06:18,430 --> 00:06:21,840
we'll add in the posts from the people
that you follow to the stream page.

117
00:06:21,840 --> 00:06:24,810
In fact, I think we're ready to do the
stream stuff now, and of course,

118
00:06:24,810 --> 00:06:26,720
by now I mean in the next stage.
