Official support has started, subscribe to activeadmin#2714 for updates!


For the reason above I'm no longer actively maintaining the projec. I will still accept any pull request for recent rails/mongoid/activeadmin and adding new specs.


Build Status Gem Version

ActiveAdmin hacks to support Mongoid. Some ActiveAdmin features are disabled or not working properly:

  • comments are disabled by default
  • filters are somehow broken

For more on Mongoid support in ActiveAdmin see this issue.


Some Gems

Add the following gems to your application's Gemfile:

gem 'activeadmin-mongoid'

You can safely remove the following lines, since are already activeadmin-mongoid dependencies:

gem 'activeadmin'
gem 'meta_search', '>= 1.1.0.pre'
gem 'sass-rails',  ['~> 3.1', '>= 3.1.4']

Remove Application Dependencies

In your config/application.rb, replace :

require 'rails/all'

with :

require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"

rails/all includes elements requiring ActiveRecord::Connection ...

Bundle & Crank


$ bundle
$ rails g devise:install
$ rails g active_admin:install

Check that the generated initializers/devise.rb file requires mongoid orm. You may find a line like this :

require 'devise/orm/mongoid'

Then create the admin user:

$ rails console
>> AdminUser.create :email => '', :password => 'password', :password_confirmation => 'password'

And that's pretty much it !
