Rails使用destroy动作进行路由

Question

在我的应用程序中,评论属于照片,我正在尝试添加一种方法来销毁评论.

的routes.rb

resources :photos do        
  resources :comments
end

CommentsController

def destroy
  @comment = Comment.find(params[:id])
  @comment.destroy
end

照片/ show.html.erb

<% @photo.comments.each do |comment| %>
  <%= comment.body %></p>
  <p><%= link_to 'Remove comment', comment, :confirm => 'Are you sure you want to remove this comment? This cannot be undone.', :method => :delete %></p>
<% end %>

我得到的错误是undefined method 'comment' for #<Photo:0x10ace9270>.

我想我可能没有正确设置我的路线,因为当我检查路线时,comment我得到:

rake routes | grep comment
              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"}

有人想过我错在哪里吗？谢谢.

<% @photo.comments.each do |comment| %>
  <%= comment.body %></p>
  <p><%= link_to 'Remove comment', [@photo, comment], :confirm => 'Are you sure you want to remove this comment? This cannot be undone.', :method => :delete %></p>
<% end %>
