Hi. In my environment.rb, I have:

ActionController::AbstractRequest.relative\_url\_root = “/foobar”

In my layout, I have:

\<%= javascript\_include\_tag :defaults %\>

Question 1:

I am getting an error:  
ActionController::RoutingError (no route found to match  
“/javascripts/prototype.js” with {:method=\>:get}):

When I remove the relative\_url\_root, everything works great. What  
gives?

Question 2:  
What is the javascript file I want to use ajax, but no visual effects?  
Can I load just one?

Thanks in advance.

Is anybody able to use javascript\_include\_tag with  
ActionController:AbstractRequest.relative\_url\_root?!

I have the same problem, I’ve tried a zillion combinations of  
configuration, and I still can’t figure out any way to solve it.

When I use the asset tag helpers with :all, :cache=\>true and  
relative\_url\_root, asset loading behavior becomes completely erratic.  
Sometimes they load, sometimes they cache, and sometimes it’s a 404.

The first time I run this in production mode, I get an error like the  
one you posted, saying the files could not be found. Rails is looking in  
a directory structure that repeats the relative\_url\_root AFTER the asset  
directory ([some.host.com/foo/public/foo/javascripts/bar.js](http://some.host.com/foo/public/foo/javascripts/bar.js)).

A resulting concatenated all.js file is created which is empty.

I’d be ok with moving my javascripts to the extra directory, but in  
development mode (without caching), they are invisible and I get the  
same same error in reverse. Furthermore in development mode, the  
timestamp is not appended to the javascript files.

I can’t tell what’s breaking what… relative\_url\_root?  
javascript\_include\_tag? :cache=\>true?

Any help would be greatly appreciated…

thanks

Bill
