Hi there, I’m getting the error: No route matches { :controller =\> “user/agentsubdomains”, :action =\> “destroy\_double”, :subdomain\_id =\> 7, :agent\_id =\> 11 } Is it not possible to put as many “whatever\_ids” as I want in the params to use them in the controller? What would I have to do where? The link looks like this: \<%= link\_to\_remote h(name), :url =\> { :controller =\> ‘user/agentsubdomains’, :action =\> ‘destroy\_double’, :subdomain\_id =\> 7, :agent\_id =\> 11 }, :method =\> ‘delete’ %\> Thanks a lot for helping me out!

What exactly are you trying to do? And what does the relevant part of your routes file look like?

I just need to assign values to - params[:subdomain\_id] and - params[:agent\_id] which are in this case - 7 and - 11 …so I can access these values in the controller using the params. And here’s the excerpt from routes.rb: ActionController::Routing::Routes.draw do |map| map.namespace :user do |user| user.resources :agentsubdomains, :member =\> { :destroy\_double =\> :delete } […] end map.resource :session […] map.root :controller =\> “root”, :action =\> “index” map.connect ‘\*path’ , :controller =\> ‘four\_oh\_fours’ end ---

Either your controller name is invalid, or you need a user\_id. I’m not sure which, but between the routing docs and your tests, you should be able to figure it out. > map.resource :session > […] > > map.root :controller =\> “root”, :action =\> “index” > > map.connect ‘\*path’ , :controller =\> ‘four\_oh\_fours’ > end Best, – Marnen Laibow-Koser [http://www.marnen.org](http://www.marnen.org) removed\_email\_address@domain.invalid ---

Thanks! (Yes, it was the user\_id that it needed…) ---

PS: Actually _any_ id does the trick (even a constant ‘dummy’ integer). It won’t be used, but the routing format apparently needs an id for the path to be composed completely. ---

That’s usually the way nested resources work by default. If it’s not accurate for your use case, change your routes (perhaps you want namespaced controllers instead).
