Papeel

Setup

rails generate papeel:initializer
rails generate papeel:migration
rake db:migrate

In config/initializer/papeel.rb, whitelist your roles (needed to validate a role):

Papeel.configure do |config|
  config.roles = [:super_admin, :admin]
end

class User < ActiveRecord::Base
  include Papeel::ActsAsPapeelUser
  acts_as_papeel_user
end

class Forum < ActiveRecord::Base
  include Papeel::ActsAsPapeelResource
  acts_as_papeel_resource
end

What it does ?

acts_as_papeel_user

instance methods

It adds a relation has_many :roles to the User class.

It adds a method named has_role? which work as follow:

user = User.find(1)
Papeel::Role.create user: user, name: :admin
user.has_role? :admin
=> true

user.has_role? :admin, any: true
=> false

# =======================================
user = User.find(2)
forum = Forum.find(1)
Papeel::Role.create user: user, name: :admin, resource: forum
user.has_role? :admin
=> false

user.has_role? :admin, any: true
=> true

user.has_role? :admin, on: forum
=> true

user.has_role? :admin, on_type: "Forum"
=> true

user.has_role? :admin, on_type: "Forum", on_id: forum.id
=> true

it generates methods based on roles specified in papeel configuration, example:

# config/initialize
Papeel.configure do |config|
  config.roles = [:super_admin, :admin]
end

# generates the following methods
user = User.find(1)
forum = Forum.find(1)

user.is_super_admin?
user.is_admin?
user.is_admin? on: forum

Those methods accept the same arguments as the has_role? method.

class methods

it adds scopes based on papeel configuration, example:

User.super_admin 
# return users who are super_admin with AND without resource,
# chain a where clause if you want to be more specific

User.admin
# same but for admin role

acts_as_papeel_resource

instance methods

It adds a polymorphic relation has_many :roles_as_resource to the resource class.
