Question

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 %>

我收到错误：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

rake路线输出：

真的不确定我做错了什么。如果我遗漏了任何重要代码，请告诉我们。

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| %>

来自docs：

以资源为导向的风格

在刚刚显示的示例中，虽然未明确指出，但我们   仍然需要使用：url选项以指定表单的位置   将要发送。但是，如果可以进一步简化   传递给form_for的记录是一种资源，即它对应于a   一组RESTful路由，例如使用资源方法定义   配置/ routes.rb中。在这种情况下，Rails将简单地推断出合适的   记录本身的URL。例如，

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

等同于：

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

-

<强>嵌套

当您为resource的{{1}}部分使用数组时，您基本上会告诉form_for将继承conversation。

我们这样使用它：

reply

这基本上对待<%= form_for [:admin, @object] do |f| %>属性，如下所示：

url：reply_conversation_path

我不知道它来自哪里url，但无论哪种方式，问题都会由mailboxer的声明引起。

-

<强>修正

有两种方法可以解决这个问题。

第一种是使用[:reply, conversation]内的url:属性，如下所示：

form_for

第二种是使用正确的格式：

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

Answer 2

每当你制作表格时，你必须记住两件事

一个。在案例回复中，您需要在控制器中初始化您的资源。我假设你正在使用会话控制器的show动作，所以你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

湾您创建资源的路径。如果你看看你的佣金路线

reply_conversation POST /conversations/:id/reply(.:format）对话#recovery 。您可以清楚地看到，您需要进行对话才能在该对话中进行回复，因此您必须在对话控制器的show动作中找到该对话，如下所示：

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

现在制作表格相对简单

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

未定义的方法`reply_mailboxer_conversation_path＆＃39;
