== Install
gem 'cancan_namespace'
== Usage
class Ability
include CanCanNamespace::Ability
def initialize(user, context = nil)
@context = context
...
if user.admin?
can :manage, :all
can :manage, :all, :context => :manage
end
end
end
=== Controller
Manage::BaseController < ApplicationController
protected
def current_ability
@current_ability ||= ::Ability.new(current_user, :manage)
end
end
In this case context extracted from controller name (:manage):
class Manage::PostsController < Manage::BaseController
before_filter :find_post, :only => [:edit, :update, :destroy]
authorize_resource
...
end
Set context for controller directly:
class People::RelationshipsController < Account::BaseController
before_filter :find_followed
before_filter :build_relation, :only => [:create]
before_filter :find_relationship, :only => [:destroy]
authorize_resource :relationship, :context => :account
...
end
=== View
<% if can? :edit, post %>
<%= link_to 'Edit', edit_post_path(post) %>
<% end %>
<% if can? :edit, post, :context => :manage %>
<%= link_to 'Edit (admin)', edit_manage_post_path(post) %>
<% end %>
