编辑：添加我的基本和子模板的完整版本。
我正在使用Django 1.5.8并且有一个基本模板（在模板根目录中）和子模板的子文件夹，它们扩展了基础。
当我扩展base.html时，基本模板的所有内容都显示在子模板的主体中。这种情况发生在除索引之外的所有子页面上。是否有一些我不知道的Django模板继承规则？
这是我的完整基础：

以下是我渲染该页面的方法（但我对其他模板使用“render_to_response”并获得相同的结果：
url(r'^about-us/', TemplateView.as_view(template_name="about-us.html"), name='about-us'),
提前感谢您的帮助。

您确定要编辑正确的＆＃34; base.html＆＃34;文件？您可能正在编辑具有相同名称但位于不同位置的文件。另外，您使用Javascript或其他东西来填充<navigation> </navigation>吗？渲染结果与您的base.html不匹配。如果您使用Javascript生成此导航部分，这可能是您的罪魁祸首。如果为了便于阅读而对其进行了编辑，那么我会搜索＆＃34; base.html＆＃34;的另一个实例。或＆＃34; about-us.html＆＃34;在您的项目文件夹中。您可能会发现您正在编辑错误的文件。你能发布完整的文件＆＃34; base.html＆＃34;和＆＃34; about-us.html＆＃34;和整个回应？
编辑：我认为问题可能出在你的＆＃34; othermeta＆＃34;块。您可以看到以下行正确呈现：
<meta charset="utf-8">
<!--<meta http-equiv="X-UA-Compatible" content="IE=edge">-->
<meta name="viewport" content="width=device-width, initial-scale=1">
这是你的结果变得混乱的一点。当您致电{% block othermeta %}时，这也是您的基地。你有内容的块有没有理由？我不确定它是否正确接受{％endblock％}。如果您希望块othermeta是动态的，则必须将其置于自己的othermeta.html中，该base.html也会扩展{% block othermeta %} {% endblock %}
。然后，您可以将代码更改为：
othermeta我认为错误可能是您尝试在扩展模板中定义此块的内容。我和你一样对此感到陌生，所以我可能完全错了，但是现在尝试完全删除{{1}}块，看看它是否有帮助。
希望这有帮助！

在2019年出现同样的问题之后，正如Majid Mobini所说，这是由于Visual Studio对源文件进行了编码。由于VS 2019不再具有“高级保存”选项，因此我的解决方案是从VS Marketplace安装“修复文件编码”扩展并重新保存我的文件-然后将元数据按预期放置在HEAD中。
