我正在尝试向我的帖子>索引页面添加一个链接，该页面允许人们向帖子的创建者发送直接消息（使用简单私人消息）。

目前我有一个指向 /messages/new 的链接来执行此操作，但这不起作用 - 当我尝试访问 /messages/new 时，我的应用程序中出现以下错误。

我想用更好的东西替换 /messages/new 的链接（在下面的 POSTS>INDEX 文件中）。如果您有任何想法，请告诉我！！

**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 %>

附加信息：应用程序本身就像 Gumtree.com，用户来这里创建帖子（例如卖我的车），人们会回复我向他们发送消息（通过 Simple Pvt Messages 插件）。

谢谢！

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

如果你想要嵌套的宁静路线，你需要类似的东西

resources :users do
  resources :messages
end

只需使用

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