Tutorial :Access CanCan's `can?` method from a model

You can get the current_user's permissions from a view or controller using can? in this fashion:

  <% if can? :update, @article %>      <%= link_to "Edit", edit_article_path(@article) %>    <% end %>

How can I access this functionality from a model using this syntax:

user.can?(:update, @article)

You need to change your User model like this:

class User < ActiveRecord::Base    def ability      @ability ||= Ability.new(self)    end    delegate :can?, :cannot?, :to => :ability  end

Then you can check abilities like this:

user.can?(:update,@article)
