the following has been happening, so started to dig into the implementation of find methods:

confirm data in mongo:

> db.users.find()
{"_id" :  ObjectId( "f3df7a4a0388833cde000000")  , "created_at" : "Thu Aug 06 2009 09:51:47 GMT-0400 (EDT)" , "updated_at" : "Thu Aug 06 2009 09:51:47 GMT-0400 (EDT)" , "email" : "blah"}
{"_id" :  ObjectId( "98e17a4ab87e084b55000000")  , "created_at" : "Thu Aug 06 2009 09:58:48 GMT-0400 (EDT)" , "updated_at" : "Thu Aug 06 2009 09:58:48 GMT-0400 (EDT)" , "email" : "blah"}
{"_id" :  ObjectId( "05e77a4a2b4c347d84000000")  , "created_at" : "Thu Aug 06 2009 10:21:57 GMT-0400 (EDT)" , "updated_at" : "Thu Aug 06 2009 10:21:57 GMT-0400 (EDT)"}
{"_id" :  ObjectId( "71f27a4a66b0febbc7000000")  , "created_at" : "Thu Aug 06 2009 11:10:41 GMT-0400 (EDT)" , "updated_at" : "Thu Aug 06 2009 11:10:41 GMT-0400 (EDT)" , "email" : "test@test.com"}
{"_id" :  ObjectId( "4ff87a4a62f037844a000000")  , "created_at" : "Thu Aug 06 2009 11:35:43 GMT-0400 (EDT)" , "updated_at" : "Thu Aug 06 2009 11:35:43 GMT-0400 (EDT)" , "email" : "f@this.com"}

Class def for User(scaled back from implementation for debugging)

class User
  include MongoMapper::Document
  
  def initialize
  end
  
  def to_json --not relevant for this case, but there so i thought id leave it. 
    j = Hash.new
    j['id'] = @_id.to_s
    j['activity'] = { 'joinedAt' => @created_at.to_i, 'stats' => {}, 'likes' => {}}
    j.to_json
  end
  
  key :email, String

end

here is the code from document.rb:162
      def find_every(options)
        criteria, options = FinderOptions.new(options).to_a        
162>>   collection.find(criteria, options).to_a.map { |doc| new(doc) }
      end


if i run the following, it works, as you can see.

>> cursor = User.collection.find({},{:fields=>nil, :offset=>0, :limit=>1, :sort=>{:$natural=>1}})
=> #<XGen::Mongo::Driver::Cursor:0x25bea80 @query=#<XGen::Mongo::Driver::Query:0x25bea94 @hint=nil, @order_by={:$natural=>1}, @number_to_return=1, @number_to_skip=0, @explain=nil, @selector={}, @fields=nil>, @collection=#<XGen::Mongo::Driver::Collection:0x74b030 @name="users", @db=#<XGen::Mongo::Driver::DB:0x2515f20 @nodes=[["localhost", 27017]], @name="hotpotato_development", @strict=nil, @pk_factory=nil, @slave_ok=nil, @auto_reconnect=nil, @semaphore=#<Object:0x2515ef8 @_mutex=#<Mutex:0x2515aac>>, @socket=#<TCPSocket:0x2515a84>, @port=27017, @host="localhost">, @hint=nil>, @db=#<XGen::Mongo::Driver::DB:0x2515f20 @nodes=[["localhost", 27017]], @name="hotpotato_development", @strict=nil, @pk_factory=nil, @slave_ok=nil, @auto_reconnect=nil, @semaphore=#<Object:0x2515ef8 @_mutex=#<Mutex:0x2515aac>>, @socket=#<TCPSocket:0x2515a84>, @port=27017, @host="localhost">, @num_to_return=1, @cache=[], @closed=false, @can_call_to_a=true, @query_run=false, @rows=nil>

this is whats getting passed into that block as doc
>> User.collection.find({},{:fields=>nil, :offset=>0, :limit=>1, :sort=>{:$natural=>1}}).to_a.map
=> #<Enumerator:0x3daba8>
