应用程序到插件 django cms 错误

Question

我想通过一个应用程序在网页上创建一个插件，但是，当将插件加载到页面时不会加载它的内容，而是在应用程序的页面上加载应用程序的内容.我认为问题可能出在插件定义的代码或模板中，我尝试了此链接中的建议http://docs.django-cms.org/en/latest/how_to/custom_plugins.html#handling-relations，但它不起作用只是运行错误。

应用程序是：https://github.com/tomwalker/django_quiz/tree/master/quiz

我一直在使用 python 3.4、django 1.8、djangoCMS 3.5

this is how the plugin content is displayed

This is how it should look, this is the content of the application

这是models.py的代码

from django.db import models
from cms.models import CMSPlugin
from quiz.models import Quiz, Question


class QuizPluginModel(CMSPlugin):
    quiz = models.ForeignKey(Quiz)

    def __unicode__(self):
        return self.quiz.question

这是cms_plugins.py的代码

from cms.plugin_base import CMSPluginBase
from cms.plugin_pool import plugin_pool
from quiz_cms_integration.models import QuizPluginModel, QuestionPluginModel
from django.utils.translation import gettext as _


@plugin_pool.register_plugin  # register the plugin
class QuizPluginPublisher(CMSPluginBase):
    model = QuizPluginModel  # model where plugin data are saved
    module = _("Quiz")
    name = _("Quiz Plugin")  # name of the plugin in the interface
    render_template = "quiz_cms_integrations/quiz_list.html"

    def render(self, context, instance, placeholder):
        context.update({'instance': instance})
        return context

这是一个模板 /quiz_list.html

{% extends 'base_q.html' %}
{% load i18n %}
{% block title %}{% trans "All Quizzes" %}{% endblock %}

{% block content %}
<h2>{% trans "List of quizzes" %}</h2>
    {% if quiz_list %}
        <table class="table table-bordered table-striped">

          <thead>
            <tr>
              <th>{% trans "Title" %}</th>
              <th>{% trans "Category" %}</th>
              <th>{% trans "Exam" %}</th>
              <th>{% trans "Single attempt" %}</th>
              <th></th>
            </tr>
          </thead>

          <tbody>

         {% for quiz in quiz_list %}

             <tr>
               <td>{{ quiz.title }}</td>
               <td>{{ quiz.category }}</td>
              <td>{{ quiz.exam_paper }}</td>
               <td>{{ quiz.single_attempt }}</td>
               <td>
                <a href="{% url 'quiz_start_page' slug=quiz.url %}">
                  {% trans "View details" %}
                </a>
            </tr>

        {% endfor %}
          </tbody>

        </table>

    {% else %}
        <p>{% trans "There are no available quizzes" %}.</p>
    {% endif %}
{% endblock %}

默认情况下，插件在上下文中以instance 的形式传递给您，您将在render 方法中看到它。但是我认为您会遇到问题，因为您的模板当前执行{% for quiz in quiz_list %}，但您的插件链接到单个测验。

基于此，您希望更新模板以检查实例；

{% extends 'base_q.html' %}
{% load i18n %}
{% block title %}{% trans "All Quizzes" %}{% endblock %}

{% block content %}
<h2>{% trans "List of quizzes" %}</h2>
    {% if instance %}
        <table class="table table-bordered table-striped">

          <thead>
            <tr>
              <th>{% trans "Title" %}</th>
              <th>{% trans "Category" %}</th>
              <th>{% trans "Exam" %}</th>
              <th>{% trans "Single attempt" %}</th>
              <th></th>
            </tr>
          </thead>

          <tbody>

             <tr>
               <td>{{ instance.quiz.title }}</td>
               <td>{{ instance.quiz.category }}</td>
               <td>{{ instance.quiz.exam_paper }}</td>
               <td>{{ instance.quiz.single_attempt }}</td>
               <td>
                <a href="{% url 'quiz_start_page' slug=instance.quiz.url %}">
                  {% trans "View details" %}
                </a>
            </tr>
          </tbody>

        </table>

    {% else %}
        <p>{% trans "There are no available quizzes" %}.</p>
    {% endif %}
{% endblock %}

如果您有一个显示所有测验的页面，您可能会更好地考虑使用应用挂钩开发您的应用程序，以便您可以将应用程序附加到 CMS 页面，那么您的应用程序将像任何应用程序一样运行常用的 django 应用程序。这方面的文档在这里； http://docs.django-cms.org/en/latest/how_to/apphooks.html
