标记未向inclusion_tag注册

Question

我不会收到错误，但是，我不能让标签显示它的内容。表格的内容应该是“废话”，

文件设置是，

​

​

crudapp_tags.py

from django import template
register = template.Library()

@register.inclusion_tag("forum.html")
def results(poll):
    form = 'blah'
    return {'form': form}

模板/forum.html

{% extends 'index.html' %}
{% load crudapp_tags %}
{% results poll %}
<p>aaa</p>
{% block homepage %}
<p>bbb</p> <!-- Only this displays -->
{% if form %}
<p>Form exists</p>
{% endif %}
{% for item in form %}
<p>This is {{ item }}</p>
{% endfor %}
    <div>
      <p>{% if user.is_authenticated %}Add a New Topic: <a href="{% url 'topic_form' %}"><span class="glyphicon glyphicon-plus"></span></a>{% endif %}</p>
    </div>
    <div>
      <p>{{ totalposts.count }} posts, {{ totaltopics.count }} topics, {{ totalusers.count }} users, {{ totalviews.numviews}} views</p>
    </div>
    <div class="post">
      {% if pModel %}
      <div class="table-responsive">
        <table class='table table-striped table-hover'>
          <thead>
            <tr>
              <th>Topic</th>
              <th>Topic Started By</th>
              <th>Last Active</th>
              <th class="table-cell-center">Views</th>
              <th class="table-cell-center">Posts</th>
            </tr>
          </thead>
          <tbody>
            {% for item in pModel %}
            <tr>
              <td><a href="{% url 'thread' item.topic_id %}">{{ item.topic.topic }}</a></td>
              <td><a href="{% url 'profile' item.topic.author_id %}">{{ item.topic.topicAuthor }}</a></td>
              <td class="icon-nowrap">{{ item.pub_date|timesince:current_time}}</td>
              <td class="table-cell-center">{{ item.topic.views }}</td>
              <td class="table-cell-center">{{ item.freq }}</td>
            </tr>
            {% endfor %}
          </tbody>
        </table>
        {% endif %}
      </div>
    </div>
    {% endblock %}

crudProject/setings.py确实包含INSTALLED_APPS中的应用程序

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'bootstrapform',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'allauth.socialaccount.providers.facebook',
    'tinymce',
    'crudapp',
]

设置似乎与这个线程中的答案Django - Simple custom template tag example相同。

为什么forum.html中没有显示“blah”？

最初，这个问题是标签没有注册。这个问题现在已经用正确的装饰符号解决了。现在的问题是标签的内容没有显示。因此，我在tag contents not displaying上提出了一个新问题

谢谢

看起来这里缺少装饰符号：register.inclusion_tag("forum.html")应该是@register.inclusion_tag("forum.html")
