Mongoid has_and_belongs_to_many associations

Question

I trying to get mongoid to save associations, but I can only get one side to work. If I have the following test.

  test "should add a user as a follower when a user follows the group" do                                                                                                                                        
    @cali_group.followers = []                                                                                                                                                
    @user1.followed_groups << @cali_group                                                                                                                                                  
    assert_equal 1, @user1.followed_groups.count
    assert_equal 1, @cali_group.followers.count
  end

Which is failing, because @cali_group.followers is []. I've been working with this for awhile, tried @cali_group.reload. But it looks like the only way to do this in my code is to work both ends of the join, i.e. @cali_group.followers << @user1. I can do that in my code if I have to.
