1. Static routing

1.1 Static route matching

stay urls.py In the file urlpatterns Configure routing .

urlpatterns Properties of

As long as the path is the same , Whether it's GET,POST, All fall into one category of requests

path and re_path

    path('index/',views.IndexView.as_view()),   # Normal routing 
    re_path(r'^[a-z]{5}/$',views.IndexView.as_view()),  # Regular expressions , As long as the conditions are met, you can get the page 

Static routing

from django.http import HttpResponse
def MyView(request):
    return HttpResponse(' View !')  
  
from django.urls import path,re_path
from myapp import views
urlpatterns = [
    path('',views.MyView),
    re_path(r"^",views.MyView),
]

2. Dynamic routing

2.1 Dynamic route parameter transmission and dynamic route converter

# Create class view 
class IndexView2(View):
    def get(self,request,id):
        return HttpResponse(f" Match to id by {id}")
# Distribution route 
from django.urls import path,re_path
from myapp import views
urlpatterns = [
    #  Dynamic routing      Specify the type 
    path('index2/<int:id>/',views.IndexView2.as_view()),
]

Regular grouping

# Create class view 
class IndexView3(View):
    def get(self,request,x,y):
        return HttpResponse(f" Match to x by {x},y by {y}")
   # Configure the routing 
from django.urls import path,re_path
from myapp import views
urlpatterns = [
# Regular grouping 
    re_path(r'^(?P<x>\d+)/(?P<y>[a-z,A-Z]+)/$',views.IndexView3.as_view())
]

Two commonly used data types

str： string matching , By default
int： integer , The matching numbers also include 0

2.2 Dynamic routing participation GET The similarities and differences of Chuan Shen

Dynamic routing parameter transmission ： Parameters participate in route matching , Get parameters in the route
GET The ginseng ： Parameters do not participate in route matching , Get parameters in view

3. Routing distribution

3.1 The concept of routing distribution

There are too many routes that need to be configured for the main route , Just distribute the route to the sub application , Let sub applications manage their own routes

3.2 Implementation of routing distribution

Create a new one under the folder of the sub application urls.py Folder , Import the module of the main route .
Import in the main route include.

# Configuration of main route 
from django.contrib import admin
from django.urls import path,include
from myapp import urls
urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include(urls)),
]
# Routing configuration in sub applications 
from django.urls import path,re_path
from myapp import views

urlpatterns = [
    path('register/',views.RegisterView.as_view()),
    path('login/',views.LoginView.as_view()),
    path('index/',views.IndexView.as_view()),
]

summary

After defining the class view in the view layer , Remember to configure the route ！！！
