谁生成django欢迎页面的默认页面? [英] Who generates the default page of django welcome page?

问题描述

我刚刚设置了django环境，正如教程所说.我输入了 python manager.py runserver，它告诉我打开 127.0.0.1:8000.当我打开它时，它与正确的欢迎页面一起工作.

I just set up the django environment and as the tutorial said. I typed python manager.py runserver and it told me to open 127.0.0.1:8000. When I open it, it worked with the correct welcome page.

但这是我的问题:谁生成了这个默认的欢迎页面?由于没有 views.py 并且 urls.py 页面是空的.

But here is my question: who generates this default welcome page? Since there is no views.py and the urls.py page is empty.

推荐答案

看一看 django/core/handlers/base.py 和 django/views/debug.py.简而言之，如果 django 得到 404，如果你没有设置任何路由，那么在 base.py

Take a look at django/core/handlers/base.py and django/views/debug.py. In a nutshell, if django gets a 404, which it will if you don't have any routes set up, then in base.py

if settings.DEBUG:
    from django.views import debug
    response = debug.technical_404_response(request, e)

在 debug.py 中查看 technical_404_response 和 empty_urlconf

And in debug.py look at technical_404_response and empty_urlconf
