Getting Started

Active Admin is released as a Ruby Gem. The gem is to be installed within a Ruby on Rails 3 application. To install, simply add the following to your Gemfile:

gem 'activeadmin'

After updating your bundle, run the installer

$> rails generate active_admin:install

The installer creates an initializer used for configuring defaults used by Active Admin as well as a new folder at app/admin to put all your admin configurations.

Migrate your db and start the server:

$> rake db:migrate
$> rails server

Visit localhost:3000/admin and log in using:

  • User:

  • Password: password

Voila! You're on your brand new Active Admin dashboard.

To register your first model, run:

$> rails generate active_admin:resource [MyModelName]

This creates a file at app/admin/my_model_names.rb for configuring the resource. Refresh your web browser to see the interface.


When upgrading to a new version of ActiveAdmin you may need to run

$> rails generate active_admin:assets

If you get:

uninitialized constant Admin::DashboardController

when trying to view the dashboard (at /admin), ensure app/admin/dashboards.rb looks like the current default.

Tools Being Used

We believe strongly in not writing code unless we have to, so Active Admin is built using many other open source projects:


Inherited Resources speeds up development by making your controllers inherit all restful actions so you just have to focus on what is important.


A DSL for semantically building amazing forms.


User authentication is done using Devise


Pagination for rails apps
