Rails 3.2.11
Ruby 2
Hi,
I am building my first rails app and decided to use Devise(2.2.4) and
Cancan(1.6.10) for auth and role management. The auth part works nicely
but
I haven’t been able to get cancan working correctly. I have one role
setup(admin). But when I try view the users index page it redirects me
to
the homepage even though I’m an admin. ANy advice on where I may be
going
wrong is most welcomed.
Here is my code:
app/models/ability.rb
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user (not logged in)
if user.role? :admin
can :manage, :all
else
can :read, :all
end
end
end
app/controllers/users_controller.rb
class UsersController < ApplicationController
load_and_authorize_resource
before_filter :authenticate_user!
def index
@users = User.all
authorize! :manage, @users
respond_to do |format|
format.html
format.json { render :json => @users }
end
end
end
app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery
def after_sign_in_path_for(resource)
root_url
end
rescue_from CanCan::AccessDenied do |exception|
redirect_to root_url, :alert => exception.message
end
def current_ability
@current_ability ||= Ability.new(current_user)
end
#load the permissions for the current user so that UI can be
manipulated
def load_permissions
@current_permissions = current_user.role.permissions.collect{|i|
[i.subject_class, i.action]}
end
end
