Rails升级到3.2 ActionNotFound奇怪的路由错误

Question

I have a rather bizarre error happening on upgrading from Rails 3.1.12 to 3.2.17.

Basically, I can load a page once, but as soon as I hit refresh, I get a

AbstractController::ActionNotFound 

I'll say that again incase you missed it. I CAN load the page, ONCE. So I know the routes are fine, but if I refresh the exact same page, I get this action not found.

This happens on every single page. I can view it once, but on refresh I can't view it again.

Ways to fix it, are to either bounce the rails server or make a change to the routes file and save it.

The routes file is way to big to post, so i'll just use a single page for an example here.
The page is found at /dashboard

The route is:

match '/dashboard', :to => 'pages#dashboard'

I hit that page, it loads fine, I hit it again, it fails with

AbstractController::ActionNotFound at /dashboard
The action 'dashboard_pages' could not be found for PagesController

The action is called "dashboard" on the pages controller.

Iv been googling this for a while now, and its the whole "1 view" thing that has be baffled. I cant find anyone else who has this problem.

Any help would be appreciated.

Heres the stack trace:

Answer 1

I found the problem.

There was a piece of code that was printing action_name << controller_name in the view. In Rails 3.1 , this just concatenated the strings and printed it. In 3.2 is alters the request parameters.
