html - 意外的keyword_ensure，期待输入结束

Question

我是 Ruby on Rails 的新手，我正在尝试创建一个具有组的网站，组有帖子，帖子有评论，每当我尝试运行我的代码时，它都会显示以下错误:

语法错误，意外的keyword_ensure，期望输入结束 在评论 View 中指向这部分代码:

    <h2>Add a comment:</h2>
    <%= render'comments/form' %>

谁能告诉我我的代码有什么问题吗？

这是我的代码:

群组显示 View :

    <p>
      <strong>Name:</strong>

您没有关闭 posts/_form.html.erb 中的第一个 form_for block 。

<%= form_for(@post) do |f| %>
  <% if @post.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>

      <ul>
      <% @post.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
<% end %>   <---- you're missing this tag
