Class Method Details

.register_ability(ability) ⇒ Object

Allows us to go beyond the standard cancan initialize method which makes it difficult for engines to modify the default Ability of an application. The ability argument must be a class that includes the CanCan::Ability module. The registered ability should behave properly as a stand-alone class and therefore should be easy to test in isolation.
