Question

Is it possible to map a subdomain to a resource? I have a company model. Currently, using subdomain_fu, my routing file contains:

map.company_root  '', :controller => 'companies', :action => 'show',
                      :conditions => { :subdomain => /.+/ }

My Company model contains a “subdomain” column.

Whilst this works as intended, it’s a named route and isn’t restful. Essentially, I need to map “name.domain.com” to the show action for the companies controller. Is a named route the way to go, or can I use a resource route?

I don’t know of a way to do this with map.resources. It does accept a :conditions option but I’m not sure how to remove the /companies/ portion of the URL. However, map.resources is primarily a convenient way to generate a bunch of named routes, which you can do manually. Something like this.

map.company '', :controller => 'companies', :action => 'show', :conditions => { :subdomain => /.+/, :method => :get }
map.new_company 'new', :controller => 'companies', :action => 'new', :conditions => { :subdomain => /.+/, :method => :get }
map.edit_company 'edit', :controller => 'companies', :action => 'edit', :conditions => { :subdomain => /.+/, :method => :get }
map.connect '', :controller => 'companies', :action => 'create', :conditions => { :subdomain => /.+/, :method => :post }
map.connect '', :controller => 'companies', :action => 'update', :conditions => { :subdomain => /.+/, :method => :put }
map.connect '', :controller => 'companies', :action => 'destroy', :conditions => { :subdomain => /.+/, :method => :delete }

Untested, but it should get you close.
