I was working on overriding boiler plate 404 Rails page in RAIlS_ROOT/public. This is Rails 3.1.1 hosted on Pasenger. I noticed that paths in the html document loose context on routes inside a controller resource path in a production environment. This is probably something basic, but wanted to put it out there.

I have

/public /public/404.html
/public/error_stylesheet/styles.css
/public/error_images/image.jpg

404.html has references to the resources 

<link href="error_stylesheets/styles.css" rel="stylesheet" type="text/css" />  
<img src="error_images/errorpageheader.jpg">

For example, If I request http://app/wrongurlname My 404.html loads with resources err_stylesheets and err_images folders are seen and retrieved.

If I request http://app/controller/wrong or //app/wrong/wrong The 404 page loads, but can't see the resources.

I was probably not interested in overriding behavior of ApplicationController or routing which seems like it would be necessary to serve erb pages. I'm not sure if serving

Maybe, you should try this kind of paths:

<link href="/error_stylesheets/styles.css" rel="stylesheet" type="text/css" />  
<img src="/error_images/errorpageheader.jpg">

Without first slash you have relative paths, but with slash you've got an absolute path you need.

  • Thanks, I tried that. Perhaps surprisingly, that doesn't work. But does work. This actually makes sense because it seems like in a 404 or 500 condition, Rails has given up on the request to the HTTP server. – radlab Nov 11 '11 at 21:43
  • And what's happen when you links to `http://yourhost.com/error_stylesheets/styles.css`? – Oleksandr Skrypnyk Nov 11 '11 at 21:46
  • That works. I should say I have this app as sub-site on domain. So I have routes like http://domain/app/route and app is symlinked public folder of a Rails app. – radlab Nov 11 '11 at 21:50
