Active Admin

Active Admin Documentation

Active Admin is a framework for creating administration style interfaces. It abstracts common business application patterns to make it simple for developers to implement beautiful and elegant interfaces with very little effort.

 # Gemfile in Rails >= 3.1
  gem 'activeadmin'
  gem 'sass-rails'
  gem "meta_search",    '>= 1.1.0.pre'

 $> rails generate active_admin:install

D:\work\haha>rails g active_admin:install
      invoke  devise
    generate    devise:install
      create    config/initializers/devise.rb
      create    config/locales/devise.en.yml
  ===============================================================================

Some setup you must do manually if you haven't yet:

  1. Ensure you have defined default url options in your environments files. Here
     is an example of default_url_options appropriate for a development environment
     in config/environments/development.rb:

       config.action_mailer.default_url_options = { :host => 'localhost:3000' }

     In production, :host should be set to the actual host of your application.

  2. Ensure you have defined root_url to *something* in your config/routes.rb.
     For example:

       root :to => "home#index"

  3. Ensure you have flash messages in app/views/layouts/application.html.erb.
     For example:

       <p class="notice"><%= notice %></p>
       <p class="alert"><%= alert %></p>

  4. If you are deploying Rails 3.1 on Heroku, you may want to set:

       config.assets.initialize_on_precompile = false

     On config/application.rb forcing your application to not access the DB
     or load models when precompiling your assets.
