Which Model Should Contain That Method?

Let’s say you have two models – each one modeling a database table – Users & Article. Here there’s nothing to deal with Zend Framwork, but you can think of them as typical models in a ZF application.

What happens if you have to write a getUserArticles method? Where would you put it? Whether this will be the User model or the Article model?

Although technically you can put it in both models my advice is to look at the SQL query. If the FROM clause is containing the user table – than put the method in the User model, but here you’d have something like:

SELECT * FROM Article WHERE user_id = 1

I’d prefer to place it in the Article model!
