Rails - May 2006 - Setting a global before_filter action in application.rb

Can you set a global before_filter action in application.rb?

So, for example, you could control authentication for all of the 
controllers in an app.?

Obviously, you would need a way to reference actions by controller 
within this "global before-filter".

Thanks,
Wes

Got it!!!

Wow, that was really easy.

If anyone''s interested in the general case of the Authenticate recipe, 
so that you can apply it to all of your app''s controllers, I have a way
to do it.

Wes-

	Yeah you can put global before_filter in application.rb. thats what  
its there for. All your other controllers inherit from this one. Just  
set it up like you would think. Then if you want to overide it in  
individual controllers you use this syntax in a normal controller:

class ApplicationController < ActionController::Base
   before_filter :authenticate_user

   protected

   def authenticate_user
     # authentication code here
   end

end



class FooController < ActionController

    skip_before_filter :authenticate_user, :only =>  
[:index, :list, :show]

   #rest of controller

end

I spoke too soon.  My error scenarios fail looking for the generic stuff 
in the specific places.

What about redirecting to templates?  I put a common login page in 
''common/login_form.rhtml'' (common is my directory under
views).

But when the actions fail, they''re trying to find a login_form template
underneath their specific view folders.

OK now I really got it.  I was rendering when I should have been
redirecting.

Still - a lot of fun!
