我在 Rails 3 中将表单路由到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|
这是错误消息：
No route matches {:action=>"/photos/42/upload", :controller=>"photos"}
...这尤其令人沮丧，因为“photos/:id/upload”是exactly此表格的正确操作。
我缺少什么？
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"}
这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”并没有更好的效果......

只是为了确认这里的另一种情况......在路线中：
resources :photos do
resources :comments
collection do
get 'update_states'
end
member do
match 'upload'
end
end
在视图中：
form_for @photo, :remote => true, :url => { :action => 'upload' }, :html => { :multipart => :true, :id => 'photo_upload' } do |f|
我仍然得到：
No route matches {:action=>"upload", :controller=>"photos"}
