Ckeditor integration

To use CKEDitor in Active Admin, you need to do two things:

1. Add Ckeditor to your Gemfile

gem 'ckeditor'

2. Add the ckeditor stylesheet to active admin (in config/initializers/active_admin.rb)

config.register_javascript 'ckeditor/ckeditor.js'

3. Change your form to a partial

ActiveAdmin.register User do
  form :partial => "user_form"

4. Add the ckeditor class to your input field in the partial (in _user_form.html.haml)

= f.input :description, :input_html => {:class => :ckeditor}

Presto! You're done :-)
