我正在学习 django，所以我打算做我的第一个 django 项目，所以我按照一些简单的默认步骤首先创建一个环境，然后简单地制作一个 "manage.py migrate" 命令。

我不知道我必须在 urls.py 文件的第 20 行中更改什么：

"""miWeb URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import include, re_path

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

Answer 1

path and re_path 都是 django.urls.

中的不同模块

您正在导入 re_path 并使用 path

将代码更改为

from django.contrib import admin
from django.urls import include, path

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

如果您想同时使用 path 和 re_path，请导入两者。

from django.urls import include, path, re_path
