This means that we need to populate both the Note: To observe best coding practices, the code I’ve put into this Controller class is usually best placed in a Service class, but to keep things as simple as possible for this tutorial I’ve just placed all the code directly into the Controller. When you do you’ll instantly receive one free gift from me (and plenty more in the future).
