Characterize

Make your models behave in special ways.

Usage

class UsersController < ApplicationController
  characterize :user

  def show
  end
end
# the above sets a helper_method of 'user' and loads UserCharacter

class UsersController < ApplicationController
  def show
    characterize(user, display_module)
  end

  def display_module
    current_user.can_edit?(user) ? AdministratedUser : StandardUser
  end
end

# use a standard interface in your views but change the character of the object

module AdministratedUser
  def edit_link
    view.link_to('Edit', admin_user_path)
  end
end

module StandardUser
  def edit_link
    ""
  end
end

Installation

Add this line to your application's Gemfile:
