回答1:
You've updated this app from an older, 2.x version of Rails. You have a line in your config/initializers/new_rails_defaults.rb that uses the ActionController::Routing constant, that constant no longer exists in Rails 4.2.
So, basically, the fix here is to upgrade your app to 4.2 properly. I could tell you to remove the ActionController::Routing line from your file, but probably that's just one of many other issues you haven't fixed here.
The weird thing here is that you haven't mentioned having the same problems in dev, which suggests you're not actually using the version of Rails in dev that you think you are.
Good luck.
