CanCanCan-BabySqueel

This is an adapter for the CanCanCan authorisation library to automatically generate SQL queries from ability rules.

This differs from the default ActiveRecord implementation in that it uses baby_squeel to generate SQL queries. This no longer uses

• includes (which incurs eager loading overhead)
• WHERE fragments, joined lexically using OR or AND or NOT.

As a side effect of using squeel, this allows self-joins in rule definitions.

Usage

In your Gemfile, insert the following line:

gem 'cancancan-baby_squeel'

after you included cancancan.
