Rails - Mar 2008 - Inheriting from AdminController intstead from ApplicationController

Hi

I would like to do the following:

I have created an admin namespace and the required folders app/admin
views/admin etc. And then I wanted all controllers under app/admin to
inherit from a controller named AdminController which resists under
app/admin/admin.rb instead of inhereting from ApplicationController,
so I could better separate between admin and public section. The
AdminController looks like this:

module Admin
  class AdminController < ActionController::Base
    include AuthenticatedSystem
    helper :all
    protect_from_forgery
    layout ''admin/layouts/admin''
  end
end


For testing the new namespace I created a GroupsController which looks
like this:

require ''admin/admin''
module Admin
  class GroupsController < AdminController
    def index
      @groups = Group.find(:all)
    end
  end
end

But every time I call the GroupsController I''m getting the following
error:

uninitialized constant Admin::AdminController


Can anybody tell me what I''m doing wrong?

Thanks
Mato

If AdminController is within admin/ I think your class name needs to
include the namespace, Admin::AdminController.  I''ve been putting
together an ''admin'' section myself by doing this and
that''s how I''ve
been doing things.

Hope this helps, I''ll keep my eye on this post to see how things go.

Hi

 I agree with Dave. You Have to include Admin::AdminController. I think this
should be the trick,else reply to this post again.

Hi

Thanks for your purposes but the problem still exists. The behaviour
of the application has now changed. The first time I call a controller
within the admin namespace it works fine, but when I reload the page
the same error occurs again.

By the way, is it possible to configure rails to load the admin.rb
file automaticly every time a controller in the admin namespace is
called (like application.rb)?

Your controller rests under app/admin/admin.rb, which won''t be loaded
automatically by rails because it doesn''t have a _controller suffix. I
would
suggest renaming this file to Admin::ApplicationController for its class and
application_controller.rb as its file name, that way it will be
automatically loaded and it will make sense what that controller''s
supposed
to be doing.

This solution works, but with one disadvantage. Now when I call
http://mydomain.com/admin/application, the
Admin::ApplicationController is called which shouldn''t be possible.
That''s why I originally wanted to build something like the normal
ApplicationController, so this one can''t be called from outside.

If you''re really fussed with that, then define an index action in there
that
redirects people to where they should be. Not many people will be trying to
go to admin/application unless they know it''s there.

I''m wondering whether you''re trying to swim upstream with the
inheritance approach inside a module. It seems you want to share some  
behaviors among your administrative controllers. Would a mixin work as  
well as direct inheritance here? E.g.:

module Admin
   class AdminController < ApplicationController
     include KewlAdminMethods
   # ...
   end
end

Any chance that would solve your problem?

Hi

I think your right Ryan, not many people will try to go to admin/
applicaton.

s.ross: This would cause the same problems, because this file would
also not be loaded properly.

Thank you guys for the help.

Admin is not a module, it''s a namespace, Admin::ApplicationController.

While the intent may be to create a namespace, it very much is a  
module. Here is the original code:

module Admin
   class AdminController < ActionController::Base
     include AuthenticatedSystem
     helper :all
     protect_from_forgery
     layout ''admin/layouts/admin''
   end
end
