未定义的方法“网友留言道” 3项目

Question

我试图将链接添加到我的帖子>索引页，它可以让人们直接发送消息（使用简单的私人信息），以邮政的创造者。

目前我有一个链接到/ messages/new来做到这一点，但这不起作用 - 当我尝试访问/消息/新时，请在我的应用程序中收到以下错误：

我想将链接替换为/ messages/new（在POSTS> INDEX文件中）下面有一些更好的东西。请告诉我，如果您有任何想法!!

**NoMethodError in Messages#new** 

Showing /Users/fkhalid2008/loand/app/views/messages/new.html.erb where line #1 raised: 

undefined method `user_messages_path' for #<#<Class:0x12a77f198>:0x12a76dce0> 

Extracted source (around line #1): 

1: <% form_for @message, :url => user_messages_path(@user) do |f| %> 
2: <p> 
3:  To:<br /> 
4:  <%= f.text_field :to %> 

其他信息：应用程序本身就像Gumtree.com，用户可以通过它来创建帖子（例如，销售我的车），并且人们回复我的消息（通过Simple Pvt Messages插件）。

谢谢！

消息模型

class Message < ActiveRecord::Base 

is_private_message 

attr_accessor :to 

end 

的routes.rb

Mysalary::Application.routes.draw do 

resources :messages do 
    collection do 
    post :delete_selected 
    end 
    end 

resources :users 
resources :profiles 
resources :pages 
resources :posts 

get "pages/home" 
get "pages/about" 
get "pages/legal" 
get "pages/feedback"

Answer 1

你的routes.rb没有定义路径user_messages_path，它很简单:)

如果您想要嵌套的宁静路线，你需要像

resources :users do 
    resources :messages 
end 

Answer 2

只需使用

<% form_for @message do |f| %> 
<% end %>
