CanCanCan-Squeel

[] (https://codeclimate.com/github/lowjoel/cancancan-squeel)

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 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.

In your Gemfile, insert the following line:

gem 'cancancan-squeel'

after you included cancancan.
