模板扩展无法正常工作- Django

Question

我有3个文件，Base.html，Navbar.html和dashboard.html。我正在尝试扩展base.html并在仪表板中包含navbar.html。它正在扩展，但问题是仪表板的内容数据是不可见的。如果我删除navbar.html，它可以工作，但没有导航栏。以下是请检查并帮助解决的文件。

Navbar.html

{% load static %}

<!-- Navbar -->

Answer 1

你可以把你的导航栏放在你的base.html中，就像我在这里做的https://github.com/YashMarmat/Blog-App-django-v3/blob/master/templates/base.html一样

在此之后，将下面的代码放在这些模板的顶部，其中您希望包含导航栏

{% extends "base.html" %}

现在，将其他模板的代码放在这两个代码之间。

{% block content %}

{% endblock content %}

例如，home.html (其他模板应如下所示)

{% extends "base.html" %}

{% block content %}

<h1>Hello World !</h1>

{% endblock content %}

就这样。
