Python django模板不存在execpt home url

我正在创建一个简单的网站。有一个奇怪的错误

模板没有在/about/

上显示，但是我的

主页

运行良好，没有临时错误。我将

home.html

和

about.html

放在同一个

目录中

并尝试了许多解决方案 实际的问题是一个URL正在工作，而另一个则不工作。请帮帮我，谢谢

Template-loader postmortem

Django tried loading these templates, in this order:

Using engine django:

    django.template.loaders.app_directories.Loader: /home/name/virtualenv/appname/3.5/lib/python3.5/site-packages/django/contrib/admin/templates/about.hmtl (Source does not exist)
    django.template.loaders.app_directories.Loader: /home/name/virtualenv/appname/3.5/lib/python3.5/site-packages/django/contrib/auth/templates/about.hmtl (Source does not exist)
    django.template.loaders.app_directories.Loader: /home/name/appname/mysite/templates/about.hmtl (Source does not exist)

您在“关于视图”中的

视图.py

文件中有一个输入错误。拼写

about.html

而不是

about.hmtl

。 就这样；）

您编写了about.hmtl而不是html…请更正：）

from django.shortcuts import render
from django.http import HttpResponse

    return render(request=request,template_name='home.html')

def about(request):
    return render(request=request,template_name='about.hmtl')
