What am I doing wrong here? I am using cancan on Rails 3. In my
Ability class, I've got:
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user, for users who are not registered
or don't have an account yet
if user.role? :admin
can :manage, :all
elsif user.role? :artist
can :read, [Artist, Painting, Video]
can :manage, Video do |video|
video.try(:user) == user
end
else
can :create, [Artist]
can :read, :all
end
end
end
In VideosController#index, I have:
<% if can? :update, song %>
<div class="interaction clearfix">
<%= link_to 'edit', '#' %>
<%= link_to 'delete', '#', :class => 'last' %>
</div>
<% end %>
I get:
undefined method `user' for :index:Symbol
