Calling Our Repository Methods

Now that we've installed and configured our DI container, let's update our 0:00 controllers actions methods to call the appropriate EntriesRepository methods. 0:04 In the first Get action method, let's return a call, 0:11 To the entriesRepository.GetList method. 0:17 And in the second Get action method, let's return a call to 0:24 the entriesRepository.Get method, passing in the id parameter. 0:28 In the Post action method, 0:40 we need to call the entriesRepository method to add the entry. 0:41 And in the Put action method, 0:51 we need to call the entriesRepository method to update the entry. 0:54 And lastly, in the Delete action method, 1:07 we need to call the entriesRepository method to delete the entry. 1:10 Set break points in the constructor in the first Get action method, and 1:22 press F5 to start debugging. 1:27 Using Postman, let's make a Get request 1:39 against the api/entries endpoint. 1:44 Here we are in the constructor for our API controller. 1:49 If we look in the Call Stack window, we can see that the Call Stack includes 1:55 a call to the SimpleInjectorWebApiInitializer.Initialize 2:00 method. 2:04 This is our controller being instantiated 2:05 as part of the DI container's verification process. 2:08 Press F5 to continue execution. 2:11 And we're in the controller constructor again. 2:14 This time, 2:17 our controller is being substantiated to handle the current request. 2:18 If we hover over the entriesRepository parameter, 2:21 we can see that we've been passed a reference to an instance which in 2:25 turn has a reference to a context class instance. 2:29 Looks like our DI container is up and running. 2:33 Press F5 to continue execution. 2:37 And here we are in the Get action method, 2:40 about to make a call to the entriesRepository.GetList method. 2:43 Go ahead and continue execution. 2:47 And we get an exception. 2:52 Right here is the exception message. 2:58 Self referencing loop detected with type 'Treehouse.FitnessFrog.Shared.Models.En- 3:01 try' Path '[0] .Activity.Entries'. 3:08 Looks like we've encountered an issue with serializing our data to JSON. 3:11 Next up, let's take a closer look at why this error's occurring, and 3:16 how we can configure the JsonSerializer to prevent it. 3:19
