Creating user roles

So far, we have discovered how a view that is accessible to a certain set of admin users can be created easily using the is_accessible() method. This can be extended to have different kinds of scenarios, where specific users will be able to view specific views. There is another way of implementing user roles at a much more granular level in a model, where the roles determine whether a user can perform all, some, or any of the CRUD operations.
