Rails 3表单，用于自定义操作 [英] Rails 3 Form For Custom Action

问题描述

我无法在Rails 3中将表单路由到自定义操作。

I'm having trouble routing a form to a custom action in Rails 3. Here are my routes:

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

以下是form_for：

Here's the form_for:

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

这是错误消息：

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

...这尤其令人沮丧，因为 photos /：id / upload正是此表格的正确动作。

... this is especially frustrating because "photos/:id/upload" is exactly the correct action for this form.

我想念什么？

编辑-这是与照片相关的原始路线：

EDITS - Here are the original Photo-related routes:

   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"}

当我将路线更改为 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，匹配效果不佳...

Unfortunately 'match' didn't work any better...

-编辑-

仅在此处确认另一种情况...在路线中使用此方案：

Just to confirm another scenario here... with this in the routes:

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

，然后在视图中显示：

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

我仍然得到：

没有路线匹配{：action => upload，：controller => photos}

推荐答案

如果您只是：url =>怎么办？ upload_photo_path（@photo）？

虽然您上载给成员似乎有些奇怪。这只是一种创建方法（在这种情况下，您应该只发布到收集路径）？

It seems a little strange that you'd be uploading to a member though. Is this just a creation method (in which case you should just POST to the collection path)?
