resource routing isn't working

Hello,

ActionController::Routing::Routes.draw do |map|
  map.resources :fs_store_entries
end

uri = make_uri
uri.path = "/fs_store_entries/#{id}"
response = Net::HTTP.post_form(uri, :_method => 'delete')

Does not get routed to FsStoreEntriesController#destroy. Why not?
Thanks for the help.

Hrm, it seems to be working now that I changed :_method to '_method'.
