python - Django 类型错误 : url() takes from 2 to 4 positional arguments but 16 were given

Question

我对 Django 非常陌生，并且遇到了另一个绊脚石。我正在将一个单独的第三方拍卖应用程序集成到我自己的项目中，在集成到我自己的项目中之前，我在应用程序中遇到错误。我似乎收到每个网址的网址错误。

Answer 1

urlpatterns 应该是模式的列表。你有，

urlpatterns = url('',
    path('admin/', admin.site.urls),
)

这是导致错误的原因。它看起来与 Django 1.8 中已弃用的语法 urlpatterns =patterns('', 类似。

应该是这样的:

from django.urls import path
from django.conf.urls import url

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^home/$', home), 
    url(r'^createuser/$', register),
    ...
]

请注意，您不能使用像 (r'^home/$', home), 这样的元组。您必须将 url() 或 re_path 与正则表达式一起使用，例如url(r'^home/$', home),，或使用新的 path() 语法。
