RAILS_ADMIN

D:\work\ra>rails g rails_admin:install
           -  Hello, RailsAdmin installer will help you sets things up!
           -  I need to work with Devise, let's look at a few things first:
           -  Checking for a current installation of devise...
           -  Adding devise gem to your Gemfile:
      append  Gemfile
     gemfile  devise
           -  Looks like you don't have devise installed! We'll install it for you:
    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.
