      Using validates_uniqueness_of on a Date field results in an undefined method 'bson_dump' error. This worked fine in Mongoid 2.4, but after upgrading to Mongoid 3.1.3, raises an error. A test case is outlined below.

      Minimal working model:

      class TestModel
	include Mongoid::Document

	field :date, type: Date
end

      Create one in a rails console:

      > t = TestModel.new
=> #<TestModel _id: 5195692f4364202f03000001, date: nil>
> t.date = Date.today
=> Thu, 16 May 2013
> t.save
=> true

      Add in a validation on the date field:

      class TestModel
	include Mongoid::Document

	field :date, type: Date

	validates_uniqueness_of :date
end

      Same test in rails console now fails to save:

      > t = TestModel.new
=> #<TestModel _id: 5195692f4364202f03000001, date: nil>
> t.date = Date.today
=> Thu, 16 May 2013
> t.save
