When adding/removing an item from a relation the {relation_name}_ids_was property does not reflect the previous state

      Given two classes

      class Item
  include Mongoid::Document

  has_and_belongs_to_many :tags
end

class Tag
  include Mongoid::Document
end

      If a tag is added to the item.tags collection. item.tag_ids_was returns the current list of ids, rather than the previous list of ids. The same holds true if a tag is removed.

      These tests demonstrate the failure

      describe "Mongoid relations" do
  let(:item){ Item.create() }
  let(:tag){ Tag.create() }

  context "when a tag is added" do
    it "reports tag_ids_was == []" do
      item.tags << tag
      item.tag_ids_was.should be_empty
    end
  end

  context "when a tag is removed" do
    before(:each){ item.tags.push(tag); item.save! }
    it "reports tag_ids_was == [tag.id]" do
      item.tags.delete tag
      item.tag_ids_was.should include(tag.id)
    end
  end
end
