Ckeditor integration

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

1. Add Ckeditor to your Gemfile

gem 'ckeditor'

for rails 3.2 use this

gem "ckeditor", "3.7.0.rc3"

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 admin/users/_user_form.html.haml) (HAML style code)

= semantic_form_for [:admin, @user] do |f|
  = f.input :description, :input_html => {:class => :ckeditor}
  = f.submit

a) If you don't want to use haml-syntax, you could also do this (in admin/users/_user_form.html.erb)

<%= semantic_form_for [:admin, @user] do |f| %>
  <%= f.input :description, :input_html => {:class => :ckeditor} %>
  <%= f.submit %>
<% end %>

Presto! You're done :-)

Or you can do in your ActiveAdmin model

ActiveAdmin.register Product do

form do |f|
  f.inputs "Details", :multipart => true do
    f.input :title

  f.inputs "Content" do
    f.input :description, :input_html => { :class => "ckeditor" }
  end
  f.buttons
end

end
