Madmin

Madmin generates an admin interface from your Active Record models, then gets out of
the way when you want to change it.

What you get

• Generated index, show, new and edit screens per model
• Association handling, including nested resources
• Search and filtering
• Plain Rails views you can override file by file

Mounting it

# Gemfile
gem "madmin"

rails generate madmin:install
rails generate madmin:resource Engine

The installer adds mount Madmin::Engine, at: "/admin" to your routes.

The trade-off

Hosted admin panels are faster to a first screen and arrive with row-level
permissions and audit logs. Madmin gives you an admin that ships with your app, is
reviewed in your pull requests, and cannot lose access to your database because a
vendor had an outage.
