Hi there,  
I’m trying to use RESTful routes with an application that has 2  
possible URL roots (e.g):

[www.example.com/yournamehere/](http://www.example.com/yournamehere/)  
and

> **[Your Name Here - Domain Name Concierge Services, Coming Soon.](http://www.yournamehere.com/)**
>
> Professional Full Service Concierge for Secure Domain Name Transactions - Leasing, Acquisitions, Co-Branding and Revshares.

(for people who wish to use their own domain name for the app)

with the same application being run for both on a mongrel cluster  
behind apache.

Ideally I wouldn’t have 2 seperate deployments, but currently I can’t  
work out how else to create a routes file that works for both such  
that I can use url\_for throught my app. I have tried adding a  
conditional to the routes file:

if request.env[‘SERVER\_NAME’].include(“[example.com](http://example.com)”)  
prefix = ‘/:artistname’  
else  
prefix = ‘’  
end

and adding the “prefix” variable to the affected routes eg:

map.artist\_cv prefix+‘/cv/:action’, :controller =\>  
‘cv\_items’, :action =\> ‘index’  
map.resources :artworks, :path\_prefix =\> prefix

Unsurprisingly nothing has worked so far! I’m not even sure if it’s  
possible to use a variable like that in a route and I can’t access  
request.env either as it hasn’t been initialised yet.

Can anyone tell me if I’m totally barking up the wrong tree, and if  
they have any better suggestions…  
thanks  
dorian

Yes you are wrong 😛

Try add this to your routes.rb when you deploy inside your document  
root.

ActionController::AbstractRequest.relative\_url\_root = ‘/username’
