Rails Routing Broken In Production - Caching of routes.rb suspected

Question

Update: Turns out that this problem was because half my mongrel did not restart. Thanks all for help!

Hi folks, i have an urgent problem. Essentially, my routing works on my localhost. But when i deployed this to production, the routes does not seem to work correctly.

For example, given a new route "/invites" - sometimes i will get a 404, and sometimes it will work correctly.

I suspect there is some caching going on somewhere, but i am not sure.

Logs: when a page is not found (when the routes are supposed to be accurate)

Answer 1

Did you make sure you restarted your server (like apache, ngix or passenger)? Also, sometimes a browser can cache urls, just close your browser and reopen it, see if that fixes it.

Also, once in a blue moon, I'll forget to push the code to GIT and therefore production server doesn't get the latest code. Just check that your server actually has the code there.

Answer 2

From the little you have posted, this definitely isn't a caching or routing problem.

It sounds like you are trying to generate a link to the previous page the person was on inside ApplicationController and you have a bug with it. You will have to post the relevant code from application_controller.rb.
