A simple decorator for Rails.
Installation
Add this line to your application's Gemfile:
gem 'trivial_decorator'
And then execute:
$ bundle
Or install it yourself as:
$ gem install trivial_decorator
Usage
Writing Decorators
Decorators inherit from TrivialDecorator::Base, live in your app/decorators directory, and are named for the model that they decorate:
# app/decorators/user_decorator.rb
class UserDecorator < TrivialDecorator::Base
def full_name
first_name + " " + last_name
end
end
Accessing helpers
# app/decorators/user_decorator.rb
class UserDecorator < TrivialDecorator::Base
def full_name
h.content_tag(:strong, first_name + " " + last_name)
end
end
Decorating Objects
# app/controllers/users_controller.rb
class UsersController < ApplicationController
def index
@users = decorate(User.all)
end
end
This will use UserDecorator, if you want to use other decorator, just pass his class name as second param to decorate.
# app/controllers/users_controller.rb
class UsersController < ApplicationController
def index
@users = decorate(User.all, OtherDecorator)
end
end
