I’m using subdomain\_fu successfully and generating subdomain routes  
like this:

rotues.rb:  
map.city\_root ‘’,:controller =\> ‘cities’, :action =\>  
‘index’, :conditions =\> { :subdomain =\> /.+/ }

using it in a view:  
\<%= link\_to city.name, city\_root\_path(:subdomain =\> city.subdomain)%\>

that works well, now I can’t figure out how to generate a nested route  
with subdomain,  
i.e. [miami.site.com/users/1](http://miami.site.com/users/1)

trying any combination of the form user\_path(@user,:subdomain =\>  
city.subdomain) does nothing excepnt append a parameter at the end of  
the url like this:

[site.com/users/1?subdomain=miami](http://site.com/users/1?subdomain=miami)

help is greatly appreciated guys!

Found the fix, it is a bug with the subdomain\_fu plugin.

In addition to the fix you found, you may also want to check out this  
patch.

[http://rails.lighthouseapp.com/projects/8994/tickets/1115-path-to-extend-named-routes-support-for-an-objects-to\_params-method](http://rails.lighthouseapp.com/projects/8994/tickets/1115-path-to-extend-named-routes-support-for-an-objects-to_params-method)

I wrote that because of a recent site I built with 18 subdomains and  
not wanting to write out all those links by hand.

In your case above you could define a to\_params method on User to  
return the hash (including the subdomain) and then just do  
user\_path(@user) and it will do the right thing.

Anyway, see the ticket for more info.
