 From the code you've shown us, it looks as though you need to spec  
the view, since I presume that's where the params[:album] which may or  
may not contain this user_id is built. The controller is just passing  
these params directly to the model's constructor, so it doesn't really  
seem to have much of a part to play as regards this specific field.

This might be a case where you'll get more value from a full-stack  
Cucumber acceptance test.
