** 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:
You just need bundler >= 1.0
bundle install bundle exec ruby spec/draper/cancan_spec.rb
