没有名为 django.conf.urls.defaults 的模块

Question

我在按照此处的指南构建 django 应用程序时遇到了一些问题：https://code.djangoproject.com/wiki/searchengine

硬件/软件：

Django 版本 2.1.4 Python 3.7 版 Windows 10 联想 Yoga 720

输入以下代码时：

from django.conf.urls.defaults import *

urlpatterns = patterns('',
(r'^/?$', 'google.searchengine.views.search'),
)

进入urls.py，命令行返回：

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x03D341E0>

    from django.conf.urls.defaults import *
ModuleNotFoundError: No module named 'django.conf.urls.defaults'

从多轮故障排除、搜索和测试看来，某些模块要么丢失，要么在较新版本的 django 中被更改。对于此事的任何帮助将不胜感激。

更新

已降级到 Python 2.7.10 和 Django 1.11.17。

Answer 1

django.conf.urls.defaults 已在 Django 中删除。如果问题出在您自己的代码中，您可以通过将导入更改为来修复它

from django.urls import include, path


urlpatterns = path('', 'google.searchengine.views.search'),

)

Answer 2

试试：

from google.searchengine.views import search
from django.urls import path

urlpatterns = [
    path('', search)
]

编辑： 如果您按照指南进行操作，我认为它实际上是：

from searchengine.views import search
from django.urls import path

urlpatterns = [
    path('', search)
]

Answer 3

django url dispatcher 自 django 2.0 以来发生了变化

from django.urls import path

from . import views

urlpatterns = [
    path('articles/2003/', views.special_case_2003),
    path('articles/<int:year>/', views.year_archive),
    path('articles/<int:year>/<int:month>/', views.month_archive),
    path('articles/<int:year>/<int:month>/<slug:slug>/', views.article_detail),
]

编辑... 在你的情况下：

from django.urls import path

urlpatterns = [
    path('/', google.searchengine.views.search),
]

但是你需要导入对应的视图，因为你的urls.py中没有google.searchengine.views.search导入

https://docs.djangoproject.com/en/2.1/topics/http/urls/

Answer 4

模块 from django.conf.urls.defaults import * 已从 Django 中删除。

你可以这样做：

from django.urls import path

urlpatterns = path('',
    (r'^/?$', google.searchengine.views.search),
)

Answer 5

我猜你有一个名为 google 的项目和一个名为 searchengine 的应用程序，（根据教程） 这样做，

from django.urls import path
from . import views

urlpatterns = [
    path('', views.search, name='search'),
]
