django 1.x版本与2.x版本 区别

django 1.x版本与2.x版本

URL区别

在django 1.x中的方式

导入的模块是'from django.conf.urls import url'，urlpatterns中url对应的是正则表达式，如下：

from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/$', admin.site.urls),
    url(r'^crm/$', include('app01.urls',namespace='app01')),
]

# 在app01.urls中
urlpatterns = [
    url(r'^login/', views.login,name='login'),
    url(r'^reg/', views.reg,name='reg'),
    url(r'^index/', views.index,name='index'),
    # url(r'^detialinfo/', views.detialinfo,name='detialinfo'),
    url(r'^customer_list/', views.CustomerList.as_view(),name='customer_list'),
    url(r'^mine_customer/', views.CustomerList.as_view(),name='mine_customer'),
    url(r'^customer_add/', views.customer_operate,name='customer_add'),
    url(r'^customer_edit/(\d+)/', views.customer_operate,name='customer_edit'),

在django 2.x中的方式

导入的模块是from django.urls import re_path,path，re_path对应的是1.x版本中的url是匹配正则表达式的，而path并不匹配正则表达式

from django.urls import re_path,path
from . import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('students.urls')),
    path('ser/', include('ser.urls')),

]

# 在ser.urls中
urlpatterns = [
    path("students/", views.StudentAPIView.as_view() ),
    path("students1/", views.StudentGenericAPIView.as_view() ),
    path("students2/", views.Student2GenericAPIView.as_view() ),
    re_path(r"^students3/(?P<pk>\d+)/$", views.Student3GenericAPIView.as_view() ),
]
