当我尝试渲染此视图时：

Reply:
<%= form_for :message, url: [:reply, conversation] do |f| %>
<%= f.text_area :body %>
<%= f.submit "Send Message", class: 'btn btn-primary' %>
<%= submit_tag 'Clear Reply Box', type: :reset, class: 'btn btn-danger' %>
<% end %>

我得到错误：undefined method 'reply_mailboxer_conversation_path'

路线：

 resources :messages do
  member do
      post :new
  end
end
resources :conversations do
  member do
      post :reply
      post :trash
      post :untrash
  end
  collection do
      get :trashbin
      post :empty_trash
  end
end

耙路线输出：

真的不知道我做错了什么。如果我遗漏了任何重要的代码，请告诉我。

您收到的错误是因为您定义form_for块的方式：

<%= form_for :message, url: [:reply, conversation] do |f| %>

从文档：

资源导向风格

在刚刚显示的示例中，虽然没有明确指出，但我们仍然需要使用 :url 选项来指定表单将被发送到哪里。但是，如果传递给 form_for 的记录是资源，则可以进一步简化，即它对应于一组 RESTful 路由，例如使用 config/routes.rb 中的资源方法定义。在这种情况下，Rails 将简单地从记录本身推断出适当的 URL。例如，

<%= form_for @post do |f| %>
  ...
<% end %>

然后相当于：

<%= form_for @post, as: :post, url: post_path(@post), method: :patch, html: { class: "edit_post", id: "edit_post_45" } do |f| %>
  ...
<% end %>

--

嵌套

当您使用数组作为 的resource一部分时form_for，您基本上是在告诉 railsconversation将继承自reply.

我们像这样使用它：

<%= form_for [:admin, @object] do |f| %>

这基本上是这样对待url属性的：

网址：reply_conversation_path

我不知道它是从哪里来mailboxer的，但无论哪种方式，问题都会由[:reply, conversation].

--

使固定

有两种方法可以解决此问题。

第一种是使用url:里面的属性form_for，像这样：

<%= form_for [:reply, @conversation], url: reply_conversation_path(conversation) do |f| %>

二是使用正确的格式：

<%= form_for @reply, url: reply_conversation_path(@conversation) do |f| %>
   ...
<% end %>

制作表格时必须牢记两件事

一个。您需要在您的控制器中初始化您的资源，在您的案例回复中。我假设您正在显示对话控制器的操作，因此您可以像这样初始化它：

@reply = Message.new   # assuming you dont have a reply model and you are using message model as reply

湾。创建资源的路径。如果您查看您的 rake 路线

reply_conversation POST /conversations/:id/reply(.:format) conversations#reply。您可以清楚地看到您需要进行对话才能在该对话中做出回复，因此您必须再次在对话控制器的显示操作中找到该对话，如下所示：

@conversation = Conversation.find(params[:id])

现在做一个表格比较简单

<% form_for @reply, url: reply_conversation_path(@conversation.id) do |f| %>
  <%= #your fields %>
<% end %>
