CanTango Roles

Roles and Role groups extension for CanTango

Status: Dec 9, 2011

Most specs except those for Permits have been completed and demonstrates that the functionality works as it should.

Ability helper

Ability::Helper
- Role
- RoleGroup

These modules are typically included into an Ability in order to access the roles of the ability subject, typically a user (or in rare cases an account).

The Role module has a #roles method which returns the role list of the subject. The RoleGroup module has a #role_groups method which returns the role group list of the subject.
