Rails 3未找到操作控制器记录 [英] Rails 3 Action Controller Record Not Found

问题描述

我使用jQuery UI Tabs与Ajax，我得到一个错误：

I'm using jQuery UI Tabs with Ajax and I am getting an error:

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

资源：3000 / messages / profile_messages

如果我转到 http：// localhost：3000 / messages / profile_messages 在我的浏览器中我获取行动控制器：异常捕获：

If I go to http://localhost:3000/messages/profile_messages in my browser I get Action Controller: Exception caught:

ActiveRecord::RecordNotFound in MessagesController#show

Couldn't find Message with ID=profile_messages

Rails.root: /Users/me/Desktop/myapp

app/controllers/messages_controller.rb:18:in `show'

Parameters:

{"id"=>"profile_messages"}

c> MessagesController＃show ：

In my MessagesController#show:

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 }
  end
end

MessagesController＃show用于单个消息，但我怎么能使它工作的我想要做什么？

The MessagesController#show is for individual messages, but how can I make it work for what I'm trying to do? I'm new to Rails and programming so sorry if this is an obvious answer.

Routes.rb ：

resources :users
resources :profiles
resources :session
resources :sessions
resources :messages do
  resources :responses
end
resource :messages do
  collection do
    get :profile_messages
  end
end

耙路线：

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"}
profile_messages_messages GET    /messages/profile_messages(.:format)               {:action=>"profile_messages", :controller=>"messages"}
         POST   /messages(.:format)  {:action=>"create", :controller=>"messages"}
new_messages GET    /messages/new(.:format)  {:action=>"new", :controller=>"messages"}
edit_messages GET    /messages/edit(.:format)  {:action=>"edit", :controller=>"messages"}
         GET    /messages(.:format)  {:action=>"show", :controller=>"messages"}
         PUT    /messages(.:format)  {:action=>"update", :controller=>"messages"}
         DELETE /messages(.:format)  {:action=>"destroy", :controller=>"messages"}

$ b < ：

def profile_messages
  @messages = User.find(@profile.user_id).messages
  respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @messages }
  end
end

推荐答案

使用 http：// localhost：3000 / messages / profile_messages 尝试访问邮件时， id => profile_messages

With http://localhost:3000/messages/profile_messages you are trying to access to the message with the id => profile_messages

您可能需要做的是：

http：// localhost：3000 / messages /：id / profile_messages

例如：

http：// localhost ：3000 / messages / 1 / profile_messages

在您的routes.rb中，您可能需要添加：

In your routes.rb, you might need to add something like:

resources :messages do
  member do
    get :profile_messages
  end
end

基于此行

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

我们使用您的控制器消息中的方法profile_messages？

Can you show us the method profile_messages from your controller messages ?

您应该更改您的路线

resources :users
resources :profiles
resources :session
resources :sessions
resources :messages do
  resources :responses
end
resource :messages do
  collection do
    get :profile_messages
  end
end

p>

to

resources :users
resources :profiles
resources :session
resources :sessions
resources :messages do
  resources :responses
  get :profile_messages, :on => :collection
end

您也可以添加

match "/messages/profile_messages" => "messages#profile_message"
