Ruby on Rails：remote_form_for不同的控制器？

Question

如何編輯Media但是在Attachment控制器中？

<% remote_form_for(@media, :controller => :attachments, 
       :action => :add_from_disk, :proposal_id => @proposal, 
       :html => { :multipart => true, :id => 'new_media', :onsubmit=>'unsaved_changes = false' }) do |f| %> 

目前，它仍然要去媒體控制器的創建操作。我不想那樣。

Answer 1

<% remote_form_for(@media, :url => url_for(:controller => :attachments, :action => :add_from_disk, :proposal_id => @proposal), 
         :html => { :multipart => true, :id => 'new_media', :onsubmit=>'unsaved_changes = false' }) do |f| %>
