RailsAdmin is a Rails engine that provides an easy-to-use interface for managing your data.

It started as a port of MerbAdmin to Rails 3 and was implemented as a Ruby Summer of Code project by Bogdan Gaza with mentors Erik Michaels-Ober, Yehuda Katz, Luke van der Hoeven, and Rein Henrichs.

Dependency Status

Dependency Status


In your Gemfile, add the following dependencies:

gem 'fastercsv' # Only required on Ruby 1.8 and below
gem 'rails_admin', :git => 'git://'


$ bundle install

And then run:

$ rails g rails_admin:install

This generator will install RailsAdmin and Devise if you don't already have it installed. Devise is strongly recommended to protect your data from anonymous users. It will modify your config/routes.rb, adding:

mount RailsAdmin::Engine => '/admin', :as => 'rails_admin'

And add an intializer that will help you getting started. (head for config/initializers/rails_admin.rb)


Start the server:

$ rails server

You should now be able to administer your site at http://localhost:3000/admin.

Submitting an Issue

We use the GitHub issue tracker to track bugs and features. Before submitting a bug report or feature request, check to make sure it hasn't already been submitted. You can indicate support for an existing issue by voting it up. When submitting a bug report, please include a Gist that includes a stack trace and any details that may be necessary to reproduce the bug, including your gem version, Ruby version, and operating system. Ideally, a bug report should include a pull request with failing specs.

Submitting a Pull Request

  1. Fork the project.
  2. Create a topic branch.
  3. Implement your feature or bug fix. NOTE - there's a small test app located in the spec/dummy_app directory that you can use to experiment with rails_admin.
  4. Add documentation for your feature or bug fix.
  5. Run bundle exec rake doc:yard. If your changes are not 100% documented, go back to step 4.
  6. Add specs for your feature or bug fix.
  7. Run bundle exec rake spec. If your changes are not 100% covered, go back to step 6.
  8. Commit and push your changes.
