I am trying to deploy my first rails app to Heroku and seem to be having a problem. After git push heroku master I get an error saying that relation "tags does not exist. I understand that without knowledge of my application it will be hard to help but I am wondering if someone can point me in the right direction. I have checked the schema.rb file and also been over all my migrations and there doesn't seem to be a problem there. The error message lead me to believe that I left something out of my routes.rb file but can't seem to find anything there either. Perhaps just some help deciphering this message.

Also, here is my routes.rb file if that helps at all.
