I have a file call authentication.rb in rails root/lib directory which
has the following method defined amongst others:
module Authentication
...
def authorize_admin?
logged_in? && has_role?(''admin'')
end
...
end
This module is included into application.rb as follows:
class ApplicationController < ActionController::Base
# Ryan''s stripped down Authentication module from
Restful_Authentication
include Authentication
# Tim Harper''s RoleRequirement module from his plugin
include RoleRequirementSystem
end
I am also using Ryan Heath''s excellent navigation_helper plugin which
has a "current_tab" class method. You set the current_tab at the
controller level as follows:
class UsersController < ApplicationController
before_filter :login_required
current_tab(self.authorize_admin? ? :clients : :basic_data)
...
end
I was trying the conditional form for setting the current tab based on
whether the logged_in? user was an "admin" or a plain
"user". That did
not work. I got the following exception:
NoMethodError in UsersController#edit
undefined method `authorize_admin?'' for UsersController:Class in line 4
which is the current_tab method above. I do not fully understand why.
The current_tab is a class method why can''t it take an argument
containing an instance method?
I got around the above issue by doing this:
class UsersController < ApplicationController
before_filter :login_required
current_tab :clients
def edit
self.class.current_tab :basic_data unless authorize_admin?
end
..
end
So at the method level, I override the current_tab based on desired
condition using the authorize_admin? method. This works.
So my question in the above context is: how do you call an instance
method as an argument to the class method?

This code runs when the class is loaded from users_controller.rb. In particular self is the class UsersController, so you can''t call authorize_admin? on it, since that is an instance method and you don''t have an instance of UsersController. In production this code only executes once (when the app starts), ie there is no request or current user - clearly you can''t be doing user specific things at this point.

Thank you Fred. You are right, I did not understand it. Now I do. I do get a bit "mixed-up" with all these "mix-ins" sometimes :) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
