Here’s one of these things that can have you go huh?
So, here’s what happened. I created new rails app from scratch
rails ajax-test
script/generate ajax_scaffold Widget Widget
script/server
=> no page worked, only error was:
Controllers::RailsInfoController: missing default helper path
rails_info_helper when trying to access environment link
Thanks to John Martin in this post for the solution.
The solution indeed was to remove all /tmp/ruby_sess* files and restart WEBrick
I got the same problem with other generator.
Clear the session variables with the rake cmd- rake tmp:clear .
This might solve your problem
Thanks for the tip. This can be especially helpful if you don’t have shell access and can only do things via capistrano.
