ruby-on-rails - Rails 不呈现部分

Question

我无法让我的页面呈现部分。当我在服务器上运行它时，它根本不呈现部分，而只是跳过它。没有错误信息。

# edit.html.erb    
<%= link_to("<< Back to List", {:action => 'list'}, :class => 'back=link')%>

<div class="subject edit">
    <h2>Edit Subject</h2>
    
    <%= form_for(:subject, :url => {:action => 'update', :id=>@subject.id}) do |f| %>
    
        <% render :partial => 'form', :locals => {:f => f} %>
    
        <div class="form-buttons">
            <%= submit_tag("Update Subject")%>
        </div>
    
    <% end %>
</div>

这是 _form.html.erb

<table summary="Subject form fields">
    <tr>
        <th>Name</th>
        <td><%= f.text_field(:name) %></td>
    </tr>
    <tr>
        <th>Position</th>
        <td><%= f.text_field(:position) %></td>
    </tr>
    <tr>
        <th>Visible</th>
        <td><%= f.text_field(:visible) %></td>
    </tr>
</table>

Answer 1

您需要 =标志:

<%= render :partial => 'form', :locals => {:f => f} %>

(你有 <% render ....)
