[fw-mvc] Best practices to organize Models/Controllers

Hello,

I am looking for some input about best practices in models/controllers.

The application is still pretty simple, but i would like to make it right from the beginning. I have two actions:

1) I have to select a specified subscriber that is active ( active = 1 in database )
2) I have to select a specified subscriber, it does not matter if active or not.

My initial approach was this in controller:

$model = new Model_Subscriber();
$model->fetchAll(array(
'email = ?' => $email,
'active = 1'
));

I soon realized that this is bad since i am writing SQL and business logic in controller. So i created two functions in model:

1) getActiveSubscriberQuery($email)
2) getSubscriberQuery($email)

Both return a Zend_Db_Select, which i can use in fetchAll().

My question: Is this the best way to do things? I mean, yhe application might get complex and i am worried about having lots and lots of functions for each type of query in model.

Regards,

Fernando Morgenstern
