Aliased field names with moped

[wielgosm]

I have a Car document which has a field with a symbol of :b, aliased as :year.

class Car 
  include Mongoid::Document

  field :a, :as => :name, :type => String
  field :b, :as => :year, :type => Integer

  belongs_to              :manufacturer
  has_and_belongs_to_many :customers

  validates :name,         :presence => true
  validates :year,         :presence => true
  validates :manufacturer, :presence => true, :uniqueness => { :scope => [:name,:year,:manufacturer] }
end

Using aliased field name with distinct does not work:

# Does not work - returns an empty array
manufacturer.cars.distinct(:year)

Using non-aliased field name works:

# It's all good!
manufacturer.cars.distinct(:b)

I was't sure if this issue should have been placed here or in the mongoid/mongoid project.

Thanks!

This should be in Mongoid, since Moped should know nothing about Mongoid... I'll move it over there.

I've fixed in Mongoid, as per the referenced commits.
