Heroku routing error rails css/javascript not loading

Question

I am fairly new with rails and ruby and heroku, and am trying to deploy an app. The deployment works, but when i try to visit the site, none of the css, or JavaScript is loading. In the log it says:

ActionController::RoutingError (No route matches [GET] 

I have tried adding gem 'rails_12factor', group: :production to my gemfile, doing assets:precompile, and a lot else, but yet the images and css still won't load. Any help would be greatly appreciated.

ruby 2.0.0
rails 4.0.0

Sounds like an asset pipeline issue. Have a look at the Heroku information for the rails asset pipeline:

https://devcenter.heroku.com/articles/rails-asset-pipeline

More than likely you'll have to precompile assets locally.

 RAILS_ENV=production bundle exec rake assets:precompile

Then just push to git and Heroku.
