Protect my admin namespace

Hi all.

I’ve an admin namespace in my app with some controllers.

What’s the best approach in order to login protect all of them?
I’m thinking about using before_filter, but I can forget to add it to
an new controller, in the future.
Googling for it, I’ve found this:

As I’ve read in the article’s comments, I could use an admin
superclass. But I can forget to inherits from it too.

So, my question is: what’s the best approach to my problem?
An Module? Superclass? before_filter?

Thank you very much and sorry for my poor English.

Create a admin/base_controller

with before_filter :login_required

And inherit from this controller class Admin::BooksController <

You only need to remember to add the inheritance in new admin


This is how I have seen it done, and how I do it myself.
