relative_url_root error while upgrading rails

Question

I'm upgrading a rails app 2.1 to 2.3.5.

After upgrading i got the error in the views

undefined method `relative_url_root' for #<ActionController>

any suggestions??

Answer 1

It does for Rails 2.1 and earlier, sort of. Under Rails 2.1 and earlier, you could set the relative_url_root via an HTTP header and Passenger did this (or seemed to). Under Rails 2.2, support for the HTTP header was removed for some reason. ( Rails commit: http://github.com/rails/rails/commit/a87462afcb6c642e59bfcd2e11e3351e... ) There's an open issue for this now:
