3. What is a Repository? A class that sits between the controller and model. Responsible for retrieving/storing data (database, file system, S3, etc).
4. My Progression Started by putting everything in the controllers and interacting directly with the models using eloquent.
5. The need for a Repository As soon as I needed to reuse some code or update a complex eloquent call, I realized more abstraction needed to occur. This is where a repository came into play.
6. Abstract Repository Since we noticed common functionality between our repositories we took it a step further and created an abstract class that all repositories inherit. This way they get tons of functionality right out of the box. Abstract Repository Methods: • function all(); • function paginate(); • function create(); • function update(); • function delete(); • function find(); • function findBy();
7. Examples
8. Controller (Old) How would you reuse code from store method in the update method? You could create a method within the controller to do this, but then it is only accessible from the HTTP layer which isn’t very reusable.
9. Controller (New) Pass the request array to the repository!
10. Repository (create) Create a new record using the model and then save additional data related to it.
11. Repository (saveAdditional) Having a saveAdditional Method allows you to reuse it in the update method. - file upload - pivot table syncing
12. Dependency Injection Construct your controllers with your repositories. This way you can reference $this->release repository anywhere!
