Question

This question is about a concept in MVC:

Supposing I have two basics entities in my system: the Post that has many PostImage (a 1:N relation).

At certain moment, I’m editing a Post and I want to delete some PostImage.

Here is my doubt: which Controller is responsible for performing the action to delete the PostImage?

a) The PostsController (the PostImage only exists inside the Post) ?
b) The PostsImageController?
c) Both are correct choices.

Note: I’m using CakePHP, but I think this is irrelevant because MVC is a concept, right?

Answer 1

PostImagesController is the one responsible for telling the PostImageModel to delete a record.

What you can do inside the PostsController is call the delete() method from the PostImage model, assuming you’ve related them correctly.

$this->Post->PostImage->delete($postImageId);
