1
00:00:01,290 --> 00:00:03,510
Let's move on to grading our ticket schema.

2
00:00:03,620 --> 00:00:10,110
So after those three interfaces I'm going to add in ticket schema is new Mongoose schema

3
00:00:12,960 --> 00:00:15,750
as the first argument we're going to provide an object inside of here.

4
00:00:15,750 --> 00:00:18,420
We're gonna list out all the different properties that we want this thing to have.

5
00:00:18,810 --> 00:00:26,600
So we wanted to have a title its type is going to be string and it is required we'll say it required

6
00:00:26,690 --> 00:00:28,840
true as a quick reminder.

7
00:00:28,850 --> 00:00:31,800
Right here we are listing out an actual value type.

8
00:00:31,820 --> 00:00:35,640
So this type thing right here is used by Mongoose not typescript.

9
00:00:35,660 --> 00:00:40,150
So when we say string right here we are referring to the global string constructor in JavaScript and

10
00:00:40,150 --> 00:00:44,260
that means we should have a capital S in all these interfaces up here.

11
00:00:44,260 --> 00:00:49,260
We're referring to a type as far as typescript is concerned this is a type specifically for typescript

12
00:00:49,530 --> 00:00:51,340
we use lowercase s up here

13
00:00:54,960 --> 00:00:56,040
beside the title.

14
00:00:56,040 --> 00:01:00,750
We will also have a price its title or assuming its type will be a number.

15
00:01:00,800 --> 00:01:11,020
And again capital N required true then finally a user I.D. its type will be string.

16
00:01:11,240 --> 00:01:12,830
It is required.

17
00:01:12,830 --> 00:01:20,850
And that's it now as the second argument into Mongoose schema we're gonna put in another object and

18
00:01:20,850 --> 00:01:25,820
this is where we're going to put in that custom to Jason function is remember we want to massage that

19
00:01:25,830 --> 00:01:34,310
idea property so we're going to add inside of the second argument to Jason I'll define the transform

20
00:01:34,310 --> 00:01:40,200
function and recall this thing takes two arguments Doc and ret.

21
00:01:40,210 --> 00:01:43,810
So red is gonna be the object that's just about to be turned in to Jason.

22
00:01:43,900 --> 00:01:46,630
So we're going to make some direct changes to that red object.

23
00:01:46,690 --> 00:01:51,520
We're not trying to return anything from the thing we're trying to modify red directly.

24
00:01:51,570 --> 00:01:57,300
So again we're going to assign the red dot idea property from Red Dot underscore I.D. and then we will

25
00:01:57,300 --> 00:02:00,270
delete red dot underscore i.e.

26
00:02:04,470 --> 00:02:11,780
that looks good after that we're going to build up that build method on our ticket schema the ticket

27
00:02:11,780 --> 00:02:15,200
schema dot static stop build.

28
00:02:15,210 --> 00:02:18,170
So this is going to be the one and only way that we create new records.

29
00:02:18,180 --> 00:02:23,040
Again just to make sure that we can typescript helping us figure out the different types of attributes

30
00:02:23,140 --> 00:02:32,470
responsibly providing we'll take in adders of type ticket adders and then we'll return new ticket and

31
00:02:32,470 --> 00:02:36,040
passing those adders and I love to s out of that argument right there.

32
00:02:36,040 --> 00:02:41,230
We merely get an air out of that that's truly okay we're gonna fix that up in just a moment so after

33
00:02:41,220 --> 00:02:47,850
we define that build method we will create the actual ticket model that's going to be Mongoose dot model

34
00:02:49,300 --> 00:02:50,590
we're gonna put in some generic types.

35
00:02:50,590 --> 00:02:58,340
This thing of ticket Doc and ticket model will then call the actual function we'll provide a name for

36
00:02:58,340 --> 00:03:05,180
the collection of tickets and the second argument is gonna be our schema to use which is ticket schema.

37
00:03:05,240 --> 00:03:09,200
I'll say that it does not wrap the line so clubs that sidebar.

38
00:03:09,200 --> 00:03:19,440
There we go and finally very last up let's export horsemeat not expect export not ticket and that should

39
00:03:19,440 --> 00:03:19,710
be at

40
00:03:22,730 --> 00:03:22,940
okay.

41
00:03:22,940 --> 00:03:28,860
So we're all done with our ticket now now that we've got that ticket model put together we can actually

42
00:03:28,890 --> 00:03:34,980
save data and retrieve data from our Mongo database to back inside of our new test file.

43
00:03:35,000 --> 00:03:38,900
Remember we've still got this comment right here reminding us that we need to make sure that somehow

44
00:03:38,930 --> 00:03:40,400
that ticket was saved.

45
00:03:40,490 --> 00:03:41,560
So we'll take a pause right here.

46
00:03:41,570 --> 00:03:45,770
We're going to implement this little check right here in the next video and we'll build out the actual

47
00:03:45,770 --> 00:03:48,380
implementation inside of our request handler itself.
