Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:01,150 --> 00:00:03,270
And now as the final one
2
00:00:03,270 --> 00:00:05,410
of the four CRUD operations,
3
00:00:05,410 --> 00:00:07,463
we have deleting documents.
4
00:00:08,550 --> 00:00:11,560
And so by now this should already be pretty familiar.
5
00:00:11,560 --> 00:00:13,910
And that's why I want to leave this one to you
6
00:00:13,910 --> 00:00:16,620
as a challenge, all right?
7
00:00:16,620 --> 00:00:18,870
So again, this one is gonna be pretty similar
8
00:00:18,870 --> 00:00:21,920
to update tour only with a small number
9
00:00:21,920 --> 00:00:24,290
of differences, but I think you can figure out
10
00:00:24,290 --> 00:00:27,480
how it works, for example, using the documentation
11
00:00:27,480 --> 00:00:30,810
and of course the other handle functions as an example.
12
00:00:30,810 --> 00:00:33,380
Okay, so keep in mind that here for example
13
00:00:33,380 --> 00:00:36,210
we used find by ID and update
14
00:00:36,210 --> 00:00:38,520
and so you probably can already guess
15
00:00:38,520 --> 00:00:42,960
how this method is gonna be called in delete tour.
16
00:00:42,960 --> 00:00:43,810
All right.
17
00:00:43,810 --> 00:00:45,030
And again, if you're not sure,
18
00:00:45,030 --> 00:00:47,380
you can take a look at the documentation
19
00:00:47,380 --> 00:00:49,950
and what kind of data it expects
20
00:00:49,950 --> 00:00:52,723
and then based on all that, try to implement it.
21
00:00:53,610 --> 00:00:54,810
Okay.
22
00:00:54,810 --> 00:00:56,910
So please pause the video here and take a minute
23
00:00:56,910 --> 00:00:59,013
to really try to do it on your own.
24
00:01:02,970 --> 00:01:05,880
Okay, hope you got that one to work
25
00:01:05,880 --> 00:01:08,443
and anyway, here goes my quick solution.
26
00:01:09,410 --> 00:01:12,510
So again, defining this one as an async function
27
00:01:14,600 --> 00:01:16,513
then try catch.
28
00:01:19,900 --> 00:01:24,623
Here is the error and then let's move this one up.
29
00:01:26,910 --> 00:01:31,910
Get this error response from over here.
30
00:01:32,380 --> 00:01:35,550
And now we are gonna use
31
00:01:35,550 --> 00:01:37,310
tour.findByIdAndDelete
32
00:01:42,513 --> 00:01:45,359
and now all this method here actually needs
33
00:01:45,359 --> 00:01:47,106
is the tour ID.
34
00:01:47,106 --> 00:01:51,910
So req.params.id and I hope you figured
35
00:01:51,910 --> 00:01:54,670
this one out from the documentation.
36
00:01:54,670 --> 00:01:57,390
Then of course we need to await in order
37
00:01:57,390 --> 00:01:59,600
for the deletion actually to happen
38
00:01:59,600 --> 00:02:01,540
and that's actually alt.
39
00:02:01,540 --> 00:02:03,780
So in this case, we actually don't save anything
40
00:02:03,780 --> 00:02:06,500
to any variable because remember,
41
00:02:06,500 --> 00:02:08,300
we actually don't send anything back
42
00:02:08,300 --> 00:02:09,900
to the client, okay.
43
00:02:09,900 --> 00:02:13,670
So in a RESTful API, it is a common practice not
44
00:02:13,670 --> 00:02:15,850
to send back any data to the client
45
00:02:15,850 --> 00:02:19,020
when there was a delete operation, okay.
46
00:02:19,020 --> 00:02:23,260
And also the 204 is kind of a standard as well.
47
00:02:23,260 --> 00:02:26,470
So give us a save now and it should actually already work
48
00:02:26,470 --> 00:02:27,610
like this.
49
00:02:27,610 --> 00:02:31,763
And so to start, let's just create some stupid tour here.
50
00:02:35,290 --> 00:02:37,620
So let's create a Jonas tour here.
51
00:02:37,620 --> 00:02:41,200
Give it a save and so,
52
00:02:41,200 --> 00:02:44,960
when we get all tours, indeed it's gonna be here
53
00:02:44,960 --> 00:02:47,233
and so let's go ahead, copy the ID,
54
00:02:48,170 --> 00:02:52,450
then open or delete tour route here
55
00:02:52,450 --> 00:02:57,270
and then all we need is to really send this delete request
56
00:02:57,270 --> 00:03:00,670
to this route, hit send.
57
00:03:01,630 --> 00:03:05,550
And so again, we get back the 204 status code
58
00:03:05,550 --> 00:03:09,900
and Postman in that case actually doesn't display anything.
59
00:03:09,900 --> 00:03:10,733
All right.
60
00:03:12,100 --> 00:03:15,400
And just to make sure, let's confirm it very quick.
61
00:03:15,400 --> 00:03:17,500
And yeah, it's gone from here.
62
00:03:17,500 --> 00:03:20,630
And so our tour was effectively deleted.
63
00:03:20,630 --> 00:03:22,830
Okay, now if you didn't manage
64
00:03:22,830 --> 00:03:25,290
to complete the challenge on your own,
65
00:03:25,290 --> 00:03:27,370
then of course that's no problem at all.
66
00:03:27,370 --> 00:03:29,800
I just wanted you to think about it
67
00:03:29,800 --> 00:03:32,140
and most of all take a look at the documentation
68
00:03:32,140 --> 00:03:34,010
on your own because it really makes
69
00:03:34,010 --> 00:03:36,290
all the difference for you to start practice
70
00:03:36,290 --> 00:03:38,900
this kind of stuff as soon as possible.
71
00:03:38,900 --> 00:03:40,930
Anyway, with this we implemented
72
00:03:40,930 --> 00:03:43,170
the basic CRUD operations.
73
00:03:43,170 --> 00:03:46,200
The next video we will then finally really start
74
00:03:46,200 --> 00:03:48,960
to model or tour a bit better.
75
00:03:48,960 --> 00:03:50,610
So right now we only have names,
76
00:03:50,610 --> 00:03:54,000
prices, and ratings, and that's not really enough
77
00:03:54,000 --> 00:03:56,750
to describe a tour and so yeah,
78
00:03:56,750 --> 00:03:59,620
in the next video we will kind of create
79
00:03:59,620 --> 00:04:02,780
a better, a bigger, more complete model.
80
00:04:02,780 --> 00:04:04,380
So I hope to see you there soon.
