python - django的代码，昨晚上还好好的，今天早上进不去管理界面了，怎么回事？谢谢。

Question

主url

就是连登陆界面都没有了，http://127.0.0.1:8001/admin/显示的是主页，也就是空的那个url指向的html页面。

Answer 1

When Django matches URLs, it matches them from top to bottom in the URL list
'' can match anything''能匹配任何东西
所以admin就无法访问了
在使用''So the admin cannot access

When using '' When matching a wide range of URL regular expressions, it is recommended to put it at the end of the URL list🎜

Answer 2

In addition to the matching problem mentioned above
There is also a misunderstanding in the way you write the URL
Like your matchingindex的时候最好使用r'^$'
Generally, the more complex the URL, the higher it is placed
