I've used multiple Rails Admin gems / engines and none of them quite work for me. This is a stab at a new one, taking inspiration from the others that works for me.

Add this line to your application's Gemfile:
gem 'tentacles'
And then execute:
$ bundle
Or install it yourself as:
$ gem install tentacles
