Django:尝试从两个视图中获取数据以显示在一个索引页上

Question

我正在尝试在我的索引页上显示来自两个不同应用程序的内容，其中有两个不同的视图。你知道吗

我做了一个视图.py为了让我的项目处理索引页，我正在尝试将我的两个应用程序中的模型实例连接到它。我没有得到任何错误，但我不能得到任何东西显示以外的东西在我的电脑基本.html. 你知道吗

下面是代码和图片，显示正在发生的事情和我正在尝试做的事情。你知道吗

def home(request, template='index.html'):
    context = {

        'color_set': Widget.objects.all(),
        }
    return render(request, template, context)

Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include

这就是我想发生的事情索引.html:

以下是实际发生的情况：

Answer 1

首先视图.py分配错误的上下文名称，只需交换它们。你知道吗

其次，如何构建模板存在问题：

那个索引.html包括widget_list（不带“.html”！）此代码定义block content的内容。已在块内容中调用。你知道吗

在我看来，您应该创建一个widget_list_inner.html，其中只包含希望在应用程序的其他部分重用的代码。你知道吗

新的widget_list.html

{% extends "base.html" %}

{% block content %}

<div class="container">
    <div class="content">
        {% include "adminpanel/widget_list_inner.html" %}
        <a class="#" href="{% url 'adminpanel:create-widget' %}">New Widget</a>
    </div>
</div>

{% endblock %}

小工具列表_内部.html你知道吗

  <div class="widgets-list">
    {% for widget in widget_list %}
        <h3>{{ widget.name }}</h3>
        <h3>{{ widget.widget_order }}</h3>
        <div>
           <p>{{ widget.body }}</p>
        </div>
    {% endfor %}
  </div>

现在你可以在你的索引.html世界上任何地方的widget_list_inner索引.html你知道吗

把同样的东西涂在颜色上_设置.html. 是的，将代码从index.html中移出。看看include的文档：https://docs.djangoproject.com/en/1.11/ref/templates/builtins/#include

如您所见，您可以将上下文值传递给include，这有助于在应用程序的任何地方重用*_inner.html模板。你知道吗
