Ruby on rails 3 未找到Rails 3操作控制器记录

我正在将jQuery UI选项卡与Ajax一起使用，但出现了一个错误：

Failed to load resource: the server responded with a status of 404 (Not Found)

资源是

如果我在浏览器中转到，我将获得动作控制器：捕获异常：

messagescoontroller#show是针对单个消息的，但是我如何才能使它适用于我要做的事情呢？我是Rails和编程新手，如果这是一个显而易见的答案，我感到非常抱歉

Routes.rb:

  respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @messages }

rake路由：

def show
  @message = Message.find(params[:id])

profile\u messages控件中的messages方法：

def show
  @message = Message.find(params[:id])
  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @message }
    format.js {render :layout => false }

您正在尝试访问id=>profile\u消息的消息

您可能需要做的是：


例如：


在routes.rb中，您可能需要添加以下内容：

resources:messages
成员do
获取：配置文件\u消息
结束
结束

=======更新========

基于此,

profile_messages_messages GET    /messages/profile_messages(.:format)               {:action=>"profile_messages", :controller=>"messages"}

您能否向我们显示控制器消息中的方法配置文件消息

=======更新========

你应该改变你的路线

资源：用户
资源：概况
资源：会议
资源：会议
资源：消息可以吗
资源：答复
结束
资源：消息可以吗
收藏办
获取：配置文件\u消息
结束
结束

到

资源：用户
资源：概况
资源：会议
资源：会议
资源：消息可以吗
资源：答复
获取：profile_消息，：on=>：集合
结束

你也可以加上

match”/messages/profile_messages=>“messages#profile_messages”
您能告诉我们您的routes.rb吗？为什么您只有一个问题\u控制器而没有消息\u控制器？你能添加实际的文件而不是rake路由的输出吗？你比我快。我添加了文件和rake路由的
消息
端。在您的消息中，控制器是
@profile
是为行
@messages=User.find（@profile.User\u id）定义的。消息
否@profile在MessagesController中的任何位置都没有定义。我应该在
show
方法或
profile\u messages
方法中定义它吗？首先尝试更改路由，但您需要定义它，因为它是在profile\u messages方法中调用的，因此没有路由匹配，我无法找到ID=profile\u问题的问题。通过匹配（并将“messages#profile_messages”更改为“messages#profile_messages”），我在
messages\u controller.rb
中为nil:NilClass`获得
未定义的方法
user_id'。所以我需要在
profile\u messages
中的
messages\u controller.rb
中定义它。太好了，现在你需要在profile\u messages中定义你的
@profile
，这样它就可以访问用户id了。
