On Mongoid 3.1.2 with bson & bson-ext version 1.8.4 , I am unable to create or save a new model object in the rails console or in the web application. Any insight on how to fix this would be appreciated. Here is a snippet that shows my errors from both attempts.

// ODM - Details of Classes and their Document
I have some simple classes as shown below:

class Game
  include Mongoid::Document
  include Mongoid::Timestamps

  embeds_many :questions
  embeds_many :players

  field :creator, :type => :String
  field :status_id, :type => :Integer
end

class Question
  include Mongoid::Document

  #embeds_many :choices
  embedded_in :game

  field :question, :type => :String
  field :answer, :type => :String
  field :choices, :type => Array
end

class Player
  include Mongoid::Document

  embedded_in :game

  field :name, :type => :String
  field :facebook_id, :type => :String
end

If I use mongoid 2.4.0, I'm able to get farther along but would rather gain the benefits of the 3.x versions. I've spent a good amount of time debugging and feel like I'm badly missing something.

-Thanks for reading through this.
