我正在尝试使用 Django 创建一个 Web 应用程序，我遇到了无法调试的未知 500 错误

Question

这是发生的错误，当我从我的模板文件夹中请求一个 .html 文件时似乎会发生这种错误，但由于某些未知的原因，它无法显示并抛出我无法处理的这些错误弄清楚几天。

如果需要更多信息，我会提供给任何提供帮助的人

Views.py

from django.shortcuts import render

# Create your views here.
def index(request):
    return render(request, 'index.html')

def about(request):
    return render(request, 'about.html')

Directory Structure

Answer 1

您正确设置了目录结构（最佳实践），现在当 Django“设置”主模板文件夹时，它看起来像这样 templates/, templates/pages/index.html, templates/pages/about .html。 render() 将自动获取 templates/ 部分，因此您必须将其余部分交给它 - render(request, 'pages/index.html')

重要 记得在 settings.py 中将 pages 应用添加到 INSTALLED_APPS

INSTALLED_APPS = [
...
'pages',
...
]

否则 Django 不会将 pages 附加到您的模板文件夹中
