I've been cracking through the Treebook videos and I've now hit a wall. I am on the "Building Social Features in Ruby on Rails" section, on the 5th Video - "Creating the Friendship" and the tests are failing with 5 errors which indicate an AssociationTypeMismatch.
I have updated my code on github and would REALLY appreciate somebody to have a look through and see if where I am going wrong as I am using this tutorial as part of a larger project and would hate to have to start all over again.
(My project is called Clonyn - not Treebook, ignore anything thats not related to Treebook :) )

Below are the test errors as copied from my terminal.

33,049 PointsHi there,
In my experience, most of the errors related to AssociationTypeMismatch has something to do with how the params are being called in the controller or the test . It might be because of line 18 of your user friendship controller. Your code has :
@friend = User.where(profile_name: params[:user_friendship][:friend_id].first)
when I believe it should be:
@friend = User.where(profile_name: params[:user_friendship][:friend_id]).first
I hope that helps!
