Question

这是路线的相关部分：

resources :photos, :path => '', :only => [:show, :new, :create, :destroy, :edit] do
  ...
end

我在视图中添加了删除照片的链接：

  <%= button_to 'Delete', @photo, :method => :delete, :confirm => 'Are you sure?' %>

但是这个视图会返回错误：

undefined method `photo_path' for #<#<Class:0x007faef8172060>:0x007faef87a7908>

destroy 方法是scaffold生成的方法。我有什么不对？

编辑： rake routes输出：

                root           /                                      photos#index
              search GET       /search(.:format)                      photos#search
      voteup_user_photo GET    /:user_id/:id/voteup(.:format)         photos#voteup
    votedown_user_photo GET    /:user_id/:id/votedown(.:format)       photos#votedown
            user_photos POST   /:user_id(.:format)                    photos#create
         new_user_photo GET    /:user_id/new(.:format)                photos#new
        edit_user_photo GET    /:user_id/:id/edit(.:format)           photos#edit
             user_photo GET    /:user_id/:id(.:format)                photos#show
                     DELETE    /:user_id/:id(.:format)                photos#destroy

您似乎有一个嵌套路线（路径需要:user_id和:id）。尝试显式传递路径参数：

button_to 'Delete', { :user_id => @user.id, :id => @photo.id }, :method => :delete, :confirm => 'Are you sure?'

如果这不起作用，您可能还需要在选项哈希中包含:action。

删除项的链接返回undefined方法
