我有一个简单的删除链接:

I have simple delete link:

给我错误:No route matches [DELETE] "/messages.316"

该如何解决?

我有ruby 1.9.3p0 Rails 3.1.1

I have ruby 1.9.3p0 Rails 3.1.1

我的路线.rb

  resources :messages do
    collection do
      get :outbox
    end
  end

当我将其更改为message_path时，我会收到wrong number of arguments (0 for 1)-> full_trace: https://gist. github.com/1967988
->所有文件: https://gist.github.com/1967994

when i change this to message_path i recieve wrong number of arguments (0 for 1) -> full_trace: https://gist.github.com/1967988
-> all files: https://gist.github.com/1967994

   outbox_messages GET    /messages/outbox(.:format)          {:action=>"outbox", :controller=>"messages"}
           messages GET    /messages(.:format)                 {:action=>"index", :controller=>"messages"}
                    POST   /messages(.:format)                 {:action=>"create", :controller=>"messages"}
        new_message GET    /messages/new(.:format)             {:action=>"new", :controller=>"messages"}
       edit_message GET    /messages/:id/edit(.:format)        {:action=>"edit", :controller=>"messages"}
            message GET    /messages/:id(.:format)             {:action=>"show", :controller=>"messages"}
                    PUT    /messages/:id(.:format)             {:action=>"update", :controller=>"messages"}
                    DELETE /messages/:id(.:format)             {:action=>"destroy", :controller=>"messages"}

推荐答案

您需要说message_path(单数)，因为它是单消息的路径:

You need to say message_path (singular) since it is the path for a single message:

link_to "Delete", message_path(message.id), :method => :delete
