Module: Allowy::Context

Extended by:
ActiveSupport::Concern
Defined in:
lib/allowy/context.rb

Overview

This module provides the default and common context for checking the permissions. It is mixed into controllers in Rails by default and provides an easy way to reuse it in other parts of the application (RSpec, Cucumber or standalone). For example, you can use this code in your Cucumber features:

@example
class CucumberContext
  include Allowy::Context
  attr_accessor :current_user

  def initialize(user)
    @current_user = user
  end

And then you can easily check the permissions like so:

@example
CucumberContext.new(that_user).can?(:create, Blog)
CucumberContext.new(that_user).should be_able_to :create, Blog
