I’m hoping someone can advise me on how to debug this routing error.

My routes.rb includes:  
resources :prospects, :only =\> [“create”]

rake routes shows:  
prospects POST /prospects(.:format)  
{:controller=\>“prospects”, :action=\>“create”}

However when I try to post a form I get:

Started POST “/prospects” for 127.0.0.1 at 2010-03-20 01:44:29

ActionController::RoutingError (No route matches “/prospects”):

Rendered /Users/ryan/.rvm/gems/ruby-1.9.1-p378/gems/  
actionpack-3.0.0.beta/lib/action\_dispatch/middleware/templates/rescues/  
routing\_error.erb within /Users/ryan/.rvm/gems/ruby-1.9.1-p378/gems/  
actionpack-3.0.0.beta/lib/action\_dispatch/middleware/templates/rescues/  
layout.erb (0.9ms)

Any ideas?

I use:

\<% form\_for @prospect do |f| %\>

which generates:

Turns out this was caused because my controller was singular  
(ProspectController) instead of plural (ProspectsController).
