Rails routes: resourcing from the root path “/”

问题

I have a Query resource that I want to route to the root of my domain. (So posting to "/" goes to the queries#create action, etc...).

My routes.rb:

root :to => "home#index"
resources :queries, :path => ''

rake routes:

           root        /                                           home#index
        queries GET    /                                           queries#index
                POST   /                                           queries#create

All seems fine, but when I try to post to "/", it is somehow getting routed to the 'root_path', even though I'm submitting it via POST. So instead of creating a new Query item, it just reloads the home page. I get this in the log:

Started POST "/" for 127.0.0.1 at 2012-04-16 20:34:58 -0400
Processing by HomeController#index as HTML

Any idea what I'm doing wrong?

Edit

When I move :root => to the very bottom of the controller, I get a redirect loop when I GET "/", which is why my ':root' definition isn't at the bottom.

Edit

It works when I replace the :root definition with get "/" => "home#index", :as => "root", but that feels too hackish to me. How do I specify what HTTP verbs to use on the root definition?

回答1:

This works:

get "/" => "home#index", :as => "root"

回答2:

Are you passing the :url => {:action = "create"} or the method in your form_for?
