Draper-CanCan (DEPRECATED)¶ ↑

** Draper-cancan is no longer to recommended way, checkout draper-cancancan to get the benefit of draper and cancan(can) without having to use custom DSL **

Draper-CanCan adds a few simple methods to your decorators to make it easier to work with cancan

Add to your gemfile:

gem 'draper-cancan'

Inside your ApplicationDecorator.rb (or a specific decorator) just add

class ApplicationDecorator < Draper::Base
  include Draper::CanCan
end

And now you’ll have access to a few helpful methods like

user_decorator.able_to? :read  #=> calls can? :read, user_decorator.model
user_decorator.unable_to? :destroy  #=> calls cannot? :destory, user_decorator.model

also you get some quick methods like

user_decorator.creatable?
user_decorator.editable?
user_decorator.updatable?
user_decorator.readable?
user_decorator.managable?
user_decorator.deletable? #or user_decorator.destroyable?

This would be pointless without the awesome work done by:

• Jeff Casimir on Draper

• Ryan Bates on CanCan

You just need bundler >= 1.0

bundle install
bundle exec ruby spec/draper/cancan_spec.rb
