Django admin- constrain visibility of models and model instances based on who logged in

Question

Using the django admin, I would like to be able to specify which models a user sees when he logs in. For a stretch goal, for each model types a user can see, I would like to specify a filter to limit which instances of the model the user can see.

Could someone please provide a pointer for how to go about achieving this?

Answer 1

Take a look at group-level permissions in the Admin (scroll down). Django 1.2 has introduced hooks for object-level permissions too

Answer 2

You can specify which models the user can see and manipulate using the admin itself. You can do this when you're logged in as a superuser.

Regarding your stretch goal, a simple answer is detailed here.
