Undefined method 'user_friendship' after creating #accept_mutual_friendship_test

I've followed Jason's directions in the Mutual Friendship video but I keep on getting the same error when running the user_friendship_test after creating the mutual_friendship tests:

1) Error: test: #accept_mutual_friendship! should accept the mutual friendship. (UserFriendshipTest): NoMethodError: undefined method user_friendship' for #<User:0x007fb13ecace88> /usr/local/rvm/gems/ruby-1.9.3-p448/gems/activemodel-3.2.12/lib/active_model/attribute_methods.rb:407:inmethod_missing' /usr/local/rvm/gems/ruby-1.9.3-p448/gems/activerecord-3.2.12/lib/active_record/attribute_methods.rb:149:in method_missing' test/unit/user_friendship_test.rb:59:inblock (2 levels) in <class:UserFriendshipTest>' /usr/local/rvm/gems/ruby-1.9.3-p448/gems/shoulda-context-1.1.6/lib/shoulda/context/context.rb:413:in instance_exec' /usr/local/rvm/gems/ruby-1.9.3-p448/gems/shoulda-context-1.1.6/lib/shoulda/context/context.rb:413:inblock in create_test_from_should_hash'

2) Error: test: #mutual_friendship! should correctly find the mutual friendship.

This is very odd to me since I am not calling the "user_friendship" method - I'm supposed to be calling the accept_mutual_friendship! and mutual_friendship methods.

user_friendship_test.rb and user_friendship.rb to follow

user_friendship.rb

def mutual_friendship
    self.class.where( { user_id: friend_id, friend_id: user_id} ).first
 end

def accept_mutual_friendship!
  # Grab the mutual_friendship and update the state without using
  # the state_machine as to not invoke callbacks.
  mutual_friendship.update_attribute(:state, 'accepted')
end

user_friendship_test.rb

context "#mutual_friendship!" do
    setup do
      UserFriendship.request users(:andrew), users(:bruce)
      friendship1 = users(:andrew).user_friendship.where(friend_id: users(:bruce).id).first
      friendship2 = users(:bruce).user_friendship.where(friend_id: users(:andrew).id).first
    end

    should "correctly find the mutual friendship" do
      assert_equal @friendship2, @friendship1.mutual_friendship
    end
  end

  context "#accept_mutual_friendship!" do
    setup do
     UserFriendship.request users(:andrew), users(:bruce)
    end

    should "accept the mutual friendship" do
      friendship1 = users(:andrew).user_friendship.where(friend_id: users(:bruce).id).first
      friendship2 = users(:bruce).user_friendship.where(friend_id: users(:andrew).id).first

      friendship1.accept_mutual_friendship!
      friendship2.reload
      assert_equal 'accepted', friendship2.state
    end
  end

Never mind - figured it out:

should be:

friendship1 = users(:andrew).user_friendships.where(friend_id: users(:bruce).id).first
friendship2 = users(:bruce).user_friendships.where(friend_id: users(:andrew).id).first

where user_friendships should replace user_friendship. I also found a few other syntax errors. Do not as I do!
