Determining which controller to write the code into!

This question is more about how things work in an MVC architecture based ORM application. I want to know which controller to write code into when there is a many to many relationship between 2 models.

Example,

I have a model A and model B with respective controllers and have a many to many realastionship. I want to list Bs that are associated with A in using bridge table. Which controller should the code for this go since both are equally related.

Hi Chirantan. Controller methods generally map to actions that are performed on models. So a method named "new" in the User model would allow you to create a new User. In other words, if you want to do something to ModelA, you'd put the method in ModelA's controller.

To answer your question, if I wanted to list all Bs associated with a particular A, I would probably create a method in the A controller called "list_Bs".

Hope that helps, Nick
