I am trying to get Cancan to work with Devise on my Rails application. I tried to follow the directions here to set it up:
I am stuck as I am getting the following error:
ArgumentError in Users::RegistrationsController#new wrong number of arguments (2 for 1)
app/models/ability.rb:7:in initialize'
app/controllers/users/registrations_controller.rb:6:incheck_permissions'
My ability.rb reads as follows:
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user
if user.role? :super_admin
can :manage, :all
elsif user.role? :admin
can :manage, :all
elsif user.role? :user
can :read, :all
# manage products, assets he owns
can :manage, Product do |product|
product.try(:owner) == user
end
can :manage, Asset do |asset|
asset.assetable.try(:owner) == user
end
end
end
end
My registrations controller reads:
class Users::RegistrationsController < Devise::RegistrationsController
before_filter :check_permissions, :only => [:new, :create, :cancel]
skip_before_filter :require_no_authentication
def check_permissions
authorize! :create, resource
end
end
This only occurs on the signup page. All other pages within the app are working fine.
