http://192.168.137.3:8000/articles/2005/Page not found (404)Request Method: GETRequest URL: http://192.168.137.3:8000/articles/2005/Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:    ^admin/    ^blog/$The current path, articles/2005/, didn't match any of these.You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.默认是去找 mysite下的urls.py文件node2:/django/mysite/mysite#cat urls.py"""mysite URL ConfigurationThe `urlpatterns` list routes URLs to views.
