python+django 更改了urls.py 之后runserver报错的解决办法

Posted 2020-08-11

新手学python+django时，更改了urls.py 为：

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns(‘‘,
    # Examples:
    # url(r‘^$‘, ‘mysite.views.home‘, name=‘home‘),
    # url(r‘^blog/‘, include(‘blog.urls‘)),

    url(r‘^admin/‘, admin.site.urls),
    url(r‘^$‘, ‘mysite.views.first_page‘),
)

 

进入mysite，启动服务器：

  python manage.py runserver 8000

却报错：ImportError: cannot import name patterns

这是因为：从1.10后django后patterns被移除了，已经没有这个模块了。

第一步，我先将

from django.conf.urls import patterns, include, url

改成

from django.conf.urls import include, url

再运行试试看，还是会报错：TypeError: view must be a callable or a list/tuple in the case of include() 

第二步，既然报这个错，那我就加上include()呗，于是将

 

url(r‘^admin/‘, admin.site.urls),

 

 

url(r‘^$‘, ‘mysite.views.first_page‘),

改成

url(r‘^admin/‘, include(admin.site.urls)),

url(r‘^$‘, include(‘mysite.views.first_page‘)),

再次运行试试看，又报错了：ImportError:Not module names‘mysite.views.first_page‘;‘mysite.views‘is not package

咋办勒？

第三步，只能去FQgoogle了，最好的解决办法是这样的，删除include包并导入mysite.views包：

 

from django.conf.urls import url
from django.contrib import admin
from mysite import views

urlpatterns = [
url(r‘^admin/‘, admin.site.urls),
url(r‘^$‘,views.first_page)
]
