Heroku + Rails 3.1: asset_path undefined?

问题

i try to deploy a rails 3.1.3 app to heroku but keep getting the following error when browsing the pages:

ActionView::Template::Error (undefined method `asset_path' for #<#<Class:0x00000002ecd630>:0x00000002e52480>):

i use the "cedar" stack as recommended by heroku. any idea why i get this issue? do i have to make some more configuration?

thanks in advance!

EDIT: works again. i forgot to add "require 'sprockets/railtie'" in the application.rb...
