an route error about prefix path if rails 2.2 rc

rubyonrails-core
1

I upgrade an app to rails 2.2 rc and deploy it to phusion passenger. However, it fails. The error msg is " ActionController::RoutingError (No route matches "/msp/projects/new" with {:method=>:get})", in which the "msp" is the prefix path. The app works well if it is start with the command "ruby script/ server" or "mongrel_rails start".

Then, I use the command "mongrel_rails start --prefix /msp ", getting the same result as above.

more error msg is below:

Could you open a ticket for this in lighthouse?

The behaviour of the relative_url_root setting changed slightly in 2.2, and we probably broke something that mongrel or passenger is expecting to be there.

The change in relative_url_root behavior was necessary for thread- safety. Passenger needs to be updated.

In the mean time, you can do it yourself by manually setting relative_url_root in your environment.rb.

I create a [ticket](http://rails.lighthouseapp.com/projects/8994/ tickets/1314-an-routingerror-of-prefix-path#ticket-1314-1) yesterday.

After I put ENV['RAILS_RELATIVE_URL_ROOT']="/msp" in the environment.rb, the app works with phusion passenger as before.
