I am trying to make a javascripts controller work. The only resource I can find on this is here : [#88 Dynamic Select Menus - RailsCasts](http://railscasts.com/episodes/88) I have tried everything in the tutorial and the comments including May 22 08 comment by “pi\_p master” for respond\_to do format etc. and here is my predicament; my application works on my development machine just fine; when I transport the application to my production environment it does not call the javascripts controller; I have the following error : 1 2 3404 Not Found 4 5 # Not Found 6 The requested URL /javascripts/dynamic\_units.js was not found on this server. 7 Now I have even tried putting in explicitly map.connect ':controller/:action.:format' as well as : map.js '/javascripts/ dynamic\_units.js' , :controller=\>'javascripts', :action =\>'dynamic\_units' and whatever permutation I could fathom but to no avail. I know the dynamic\_units method in javascripts\_controller is not called because the logger never outputs any lines. ---

I had to comment out a line in its httpd ssl conf file that was causing apache to serve a javascript directory statically and bypassing the appserver (mongrel). ---

I’m trying to do this now as well. Even in my development machine it says that the js file doesn’t exist. Ryan B. said in the podcast though that if it doesn’t find the static file, it will then go to the controller. So, it shouldn’t have been because of the apache config right?

So, it shouldn’t have been because of the apache config > right? Nope. What Ryan meant was that the Rails Application server will serve the static file if it exists, and if not, go to the controller. This decision is done by Rails, so it has to be done on the acutal app server like mongrel. If you let apache serve the static files, and proxy all other requests to mongrel, the call for this URL will never reach your mongrel as apache sees it as a requests to a static file. Long story cut short: If you would run on mongrel directly, it should work. if you have a frontend server that serves static content, it won’t. You can easily circumvent it by not naming the controller JavascriptsController, but something else e.g. DynjavascriptsController. That way, apache can still serve the real static js files, while the dynamic js files are handled by rails. ---

I see. It’s working now in development environment, i had to add a route for it! I must’ve missed that his in screencast. Thanks for the clarification! You’re suggestion sounds right, and I’ll change the name of my controller so I won’t run into problems while in production.

Who is saying the file doesn’t exist (apache, mongrel, something else?) what is your development setup Fred
