A Data Mapper implementation of roles generic

The following role strategies from Roles Generic are currently supported

roles_mask
role_string

See roles_active_record and roles generic for more info on using the API.

Roles Generator

The library comes with a Rails 3 generator that lets you populate a user model with a given role strategy The following role strategies are included by default. Add your own by adding extra files inside the strategy folder, one file for each role strategy is recommended.

admin_flag
many_roles
one_role
roles_mask
role_string

Update Oct 10.

Bugfix: Added dependencies to Rakefile for role generator so they should work out-of-the-box after gem is installed ;)

Usage examples

Apply :admin_flag Role strategy to User model using default roles :admin and :guest (default)

$ rails g data_mapper:roles User --strategy admin_flag

Apply :admin_flag Role strategy to User model using default roles and extra role :author

$ rails g data_mapper:roles_migration User --strategy admin_flag --roles author

Apply :one_role Role strategy to User model without default roles, only with roles :user, :special and :editor

$ rails g data_mapper:roles_migration User --strategy one_role --roles user special editor --no-default-roles
