Question

我正在浏览railstutorial.org书，在app / controllers / pages_controller.rb中添加了一个微博实例变量后，我的应用程序的主页无法呈现，而是在浏览器上给出了以下错误：< / p>

ActionView::MissingTemplate in Pages#home

Showing /app/views/pages/home.html.erb where line #9 raised:

这是我的home.html.erb文件：

<% if signed_in? %>
  <table class="front" summary="For signed-in users">
    <tr>
      <td class="main">
        <h1 class="micropost">What's up?</h1>
        <%= render 'shared/micropost_form' %>
      </td>
      <td class="sidebar round">
        <%= render 'shared/user_info' %>
      </td>
    </tr>
  </table>
<% else %>
  <h1>Sample App</h1>

  <p>
    This is the home page for the
    <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
    sample application.
  </p>

  <%= link_to "Sign up now!", signup_path, :class => "signup_button round" %>
<% end %>

这是我的_user_info.html.erb文件：

<div class="user_info">
  <a href="<%= user_path(current_user) %>">
    <%= gravatar_for current_user, :size => 30 %>
    <span class="user_name">
      <%= current_user.name %>
    </span>
    <span class="microposts">
      <%= pluralize(current_user.microposts.count, "micropost") %>
    </span>
  </a>
</div>

我不认为我在遵循教程时犯了错误。我甚至看过类似的线程stackoverflow.com线程，但无济于事：

有没有人有任何想法？

Answer 1

您需要添加视图app/views/shared/_user_info.html.erb。我猜你的路径错了。

Answer 2

看起来你没有通过步骤如代码清单11.30所示：

def home
  @title = "Home"
  @micropost = Micropost.new if signed_in?
end

但我不知道为什么它反映在渲染user_info partial：（

Answer 3

在app / views / shared / _user_info.html.erb

中缺少以下代码

<div class="user_info">
    <a href="<%= user_path(current_user) %>">
    <%= gravatar_for current_user, :size => 30 %>
    <span class="user_name">
        <%= current_user.name %>
    </span>
    <span class="microposts">
        <%= pluralize(current_user.microposts.count, "micropost") %>
    </span>
    </a>
</div>
