Overview

singleton

Singletons are usually used in associations which are related through has_one and belongs_to. You declare those associations like this:

class ManagersController < InheritedResources::Base
  belongs_to :project, :singleton => true
end

But in some cases, like an AccountsController, you have a singleton object that is not necessarily associated with another:

class AccountsController < InheritedResources::Base
  defaults :singleton => true
end

Besides that, you should overwrite the methods :resource and :build_resource to make it work properly:

class AccountsController < InheritedResources::Base
  defaults :singleton => true

  protected
    def resource
      @current_user.account
    end

    def build_resource(attributes = {})
      Account.new(attributes)
    end
end

When you have a singleton controller, the action index is removed.
