Rails 3表单用于自定义操作

Question

我在将表单路由到Rails 3中的自定义操作时遇到问题.以下是我的路由:

resources :photos do
    resources :comments
    collection do
        get 'update_states'
    end
    member do
        put 'upload'
    end
end

这是form_for:

form_for @photo, :remote => true, :url => { :action => upload_photo_path(@photo) }, :html => { :multipart => :true, :method => 'put' } do |f|

这是错误信息:

No route matches {:action=>"/photos/42/upload", :controller=>"photos"}

...这尤其令人沮丧,因为"photos /:id/upload" 正是此表单的正确操作.

我错过了什么？

编辑 - 以下是与照片相关的原始路线:

   photo_comments    GET    /photos/:photo_id/comments(.:format)          {:action=>"index", :controller=>"comments"}
                     POST   /photos/:photo_id/comments(.:format)          {:action=>"create", :controller=>"comments"}
   new_photo_comment GET    /photos/:photo_id/comments/new(.:format)      {:action=>"new", :controller=>"comments"}
  edit_photo_comment GET    /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}
       photo_comment GET    /photos/:photo_id/comments/:id(.:format)      {:action=>"show", :controller=>"comments"}
                     PUT    /photos/:photo_id/comments/:id(.:format)      {:action=>"update", :controller=>"comments"}
                     DELETE /photos/:photo_id/comments/:id(.:format)      {:action=>"destroy", :controller=>"comments"}
update_states_photos GET    /photos/update_states(.:format)               {:action=>"update_states", :controller=>"photos"}
        upload_photo PUT    /photos/:id/upload(.:format)                  {:action=>"upload", :controller=>"photos"}
              photos GET    /photos(.:format)                             {:action=>"index", :controller=>"photos"}
                     POST   /photos(.:format)                             {:action=>"create", :controller=>"photos"}
           new_photo GET    /photos/new(.:format)                         {:action=>"new", :controller=>"photos"}
          edit_photo GET    /photos/:id/edit(.:format)                    {:action=>"edit", :controller=>"photos"}
               photo GET    /photos/:id(.:format)                         {:action=>"show", :controller=>"photos"}
                     PUT    /photos/:id(.:format)                         {:action=>"update", :controller=>"photos"}
                     DELETE /photos/:id(.:format)                         {:action=>"destroy", :controller=>"photos"}

以下是我更改路线时的相关路线match 'upload':

 photo_comments GET    /photos/:photo_id/comments(.:format)          {:action=>"index", :controller=>"comments"}
                     POST   /photos/:photo_id/comments(.:format)          {:action=>"create", :controller=>"comments"}
}
   new_photo_comment GET    /photos/:photo_id/comments/new(.:format)      {:action=>"new", :controller=>"comments"}
  edit_photo_comment GET    /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}
       photo_comment GET    /photos/:photo_id/comments/:id(.:format)      {:action=>"show", :controller=>"comments"}
                     PUT    /photos/:photo_id/comments/:id(.:format)      {:action=>"update", :controller=>"comments"}
                     DELETE /photos/:photo_id/comments/:id(.:format)      {:action=>"destroy", :controller=>"comments"}
update_states_photos GET    /photos/update_states(.:format)               {:action=>"update_states", :controller=>"photos"}
        upload_photo        /photos/:id/upload(.:format)                  {:action=>"upload", :controller=>"photos"}
              photos GET    /photos(.:format)                             {:action=>"index", :controller=>"photos"}
                     POST   /photos(.:format)                             {:action=>"create", :controller=>"photos"}
           new_photo GET    /photos/new(.:format)                         {:action=>"new", :controller=>"photos"}
          edit_photo GET    /photos/:id/edit(.:format)                    {:action=>"edit", :controller=>"photos"}
               photo GET    /photos/:id(.:format)                         {:action=>"show", :controller=>"photos"}
                     PUT    /photos/:id(.:format)                         {:action=>"update", :controller=>"photos"}
                     DELETE /photos/:id(.:format)                         {:action=>"destroy", :controller=>"photos"}

不幸的是'匹配'没有任何效果......

只是为了确认另一个场景......在路线中有这个:

resources :photos do
    resources :comments
    collection do
        get 'update_states'
    end
    member do
        match 'upload'
    end
end

这在视图中:

form_for @photo, :remote => true, :url => { :action => 'upload' }, :html => { :multipart => :true, :id => 'photo_upload' } do |f|

我还是得到:

No route matches {:action=>"upload", :controller=>"photos"}

怎么样:url => upload_photo_path(@photo)？

你上传给会员似乎有点奇怪.这只是一种创建方法(在这种情况下你应该只是POST到收集路径)？
