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

Example: _onerole strategy

end  

h2. Rails generators

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

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.

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

$ rails g mongoid:roles User --strategy admin_flag

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

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

h2. Note on Patches/Pull Requests

• 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.
