Reviewing the Comic Book Artists Repository

How did it go? 0:00 Were you able to move the comic book artists related repository methods 0:01 to their own repository class? 0:05 Let's walk through my solution. 0:07 I started by adding the class named ComicBookArtistsRepository 0:09 to the class library's data folder. 0:13 To which I added a private field for the context instance and 0:15 a constructor that accepts a context instance, and 0:19 initializes the private field to that instance. 0:22 I then moved the GetComicBookArtist, AddComicBookArtist, and 0:25 DeleteComicBookArtist methods from the Repository class to 0:29 the ComicBookAristRepository class. 0:33 And added the using directives for the comic book shared models and 0:38 system data entity name spaces. 0:42 After I move the methods to the new class, 0:49 I renamed the GetComicBookArtist method to Get. 0:52 The AddComicBookArtist method to Add, and 1:03 the DeleteComicBookArtist method to Delete. 1:06 That keeps the entity type focused repositories 1:12 following the same method naming convention. 1:15 Then I moved on to the ComicBookArtistsController class and 1:18 added a private field from the new repository and 1:21 instantiated an instance of it in the constructor. 1:24 Then I finished up by fixing the build errors in the controller. 1:40 Repository.AddComicBookArtist became _comicBookArtistsRepository.Add. 1:46 Repository.GetComicBookArtist became _comicBookArtistRepository.Get. 1:58 Repository.DeleteComicBookArtist became _comicBookArtistsRepository.Delete. 2:10 Once the project was successfully building again, I ran the web app and 2:18 tested each page. 2:22 Remember, it's okay if you did things slightly differently than I did. 2:31 There's often more than one way to do something. 2:35 Let's take a closer look at our two entity type focused repositories. 2:38 I'll open them and place them in side by side tabs. 2:42 They both contain private fields for their context instances and initialized 2:48 those fields using a constructor that accepts a context instance. 2:52 They also both contain a Get method, 3:00 though the signature of those methods differ slightly. 3:02 The CRUD related methods are also very similar, 3:06 basically just varying by the entity type they're operating against. 3:08 So our repository classes look very similar to each other. 3:16 Which might make you wonder if there's a way that we can reduce some of this 3:20 very close to the same code. 3:24 While still retaining our entity type focused repositories. 3:25 Well, it turns out there is something that we can do. 3:29 We'll see exactly what in the next video. 3:33
