Update Dec 24, 2010

Embedded role:

Please join in the effort to implement and add these embedded strategies to the mix. They have so far been implemented successfully for Mongoid.

gem install roles_mongo_mapper

Insert in Gemfile:

gem 'roles_mongo_mapper'

Run $ bundle install from terminal

Alternatively install using Cream

Example: role_string strategy

class User
  include MongoMapper::Document  
  include Roles::MongoMapper 

  strategy :one_role
  valid_roles_are :admin, :guest, :user
end

Example: one_role strategy

class User
  include MongoMapper::Document  
  include Roles::MongoMapper 

  strategy :one_role
  valid_roles_are :admin, :guest, :user
end

The library comes with a Rails 3 generator that lets you populate a user model with a role strategy of your choice.

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

$ rails g mongo_mapper:roles User --strategy admin_flag

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

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

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
