     183      # Creates a form that will submit using XMLHttpRequest in the background  
     184      # instead of the regular reloading POST arrangement and a scope around a  
     185      # specific resource that is used as a base for questioning about 
     186      # values for the fields.   
     187      # 
     188      # === Resource  
     189      # 
     190      # Example: 
     191      #   <% remote_form_for(@post) do |f| %> 
     192      #     ... 
     193      #   <% end %>

     200      # 
     201      # === Nested Resource  
     202      # 
     203      # Example: 
     204      #   <% remote_form_for([@post, @comment]) do |f| %> 
     205      #     ... 
     206      #   <% end %>

     211      #     ... 
     212      #   <% end %> 
     213      # 
     214      # If you don't need to attach a form to a resource, then check out form_remote_tag. 
     215      # 
     216      # See FormHelper#form_for for additional semantics.
