Cantango Demo

Welcome to the Cantango Rails 3 Demo application!

This demo app aims to demonstrate how to use CanTango in a Rails 3 application.

Integrations

Integrations to be included are:

• Devise – Authentication
• Troles – Roles and Rolegroups
• Active Admin – Admin UI
• CanTango editor – Web UI interface to manage permissions

Engines

The following CanTango engines will be demonstrated, working together:

• Permissions
• Permits
• User AC

Caching

The engines will be executed in the following cache configuration

• Permissions – Cache
• Permits – Cache and No Cache
• User AC – Cache

The No Cache mode for Permits, will allow inclusion of permit rules that can NOT be cached due to dynamic conditional logic surrounding them. Here a very simplistic example to illustrate such a scenario:

def permit_rules
  if the_sky_is_falling?
   can :reach, Sky
  else
   cannot :reach, Sky
  end
end
