Undefined method 'imdb_star_rating_for'

I am getting this error when I try to use ratyrate. I have been following the tutorial. The weird thing is when I ender the same information from the live shell, I dont get an error. You can see in the screen shot below. Any ideas? I figure it has something to do with the fact that I am using single table inheritance and I have a User model and two models, client and guide that inherit from it. Any help would be extremely useful!

Thanks, Macgill
