Question

Anyone get Rails 3.1 RC5 running on Heroku, Cedar stack? Everything seems to work so far, except that asset images (such as logo, icons, main_bg, etc.) are not being displayed.

I’m not sure if it is related to this issue.

Would like to hear from anyone who was able to fix this problem.

Answer 1

Tweaking this setting should no longer be necessary in Rails 3.1, but if you’re upgrading from earlier versions of 3.1 RC, either comment out the x_sendfile_header setting, or set it to nil in your production.rb file:

config.action_dispatch.x_sendfile_header = nil

This is the setting recommended in the Heroku docs.
