Django-urls (routing)

The Django routing entry is the urlpatterns parameter of the urls.py .
Distribute requests to individual view functions or classes by locating the corresponding relationships in urlpatterns .

First, distribute the request to the function
1. You should define the processing function in the views.py of the corresponding app, such as:

1 def business_new (Request): 2     return HttpResponse ("Django")

2, import the corresponding module in the urls.py

1  from Import views

3, in the Urlpatterns to join the corresponding relationship

1 path ('app1/', views.business_new) #fbv function Base View

Ii. distribution of requests to classes
1. You should define the processing class in the views.py of the corresponding app, such as:

1  fromDjango.viewsImportView2 classBlog (View):#should inherit view3     defDispatch (self, request, *args, * *Kwargs):4         Print("before")5result = Super (blog,self). Dispatch (Request, *args, **kwargs)#distributed on request6         Print(" After")7         returnresult8 9     defGet (self,request):Ten         returnHttpResponse ("BLOG") One  A     defPost (self,request): -         Pass

2, import the corresponding module in the urls.py

1  from Import views

3, in the Urlpatterns to join the corresponding relationship

1 path ('blog/', views. Blog.as_view ()),     #CBV    class Base View

Third, the special wording of the route
1, the use of regular, such as:

1 re_path ('article-(\d+)-(\d+)/', views.article)2 Re_path ('article-(? p<article_type_id>\d+)-(? p<category_id>\d+)/', views.article) # Group

can be accessed in the same way as the address/article-1-2:
Method Two will pass 1 to article_type_id,2 to category_id

The Re_path method should be imported when using regular

1  from Import Path,re_path

2. The name attribute, such as

1 re_path ('article-(? p<article_type_id>\d+)-(? p<category_id>\d+)/', views.article,name='article')

After you set this property, you can reverse-generate the URL by using the reverse method, such as:

1 file:views.py 2  from Import Reverse 3 def article (request,**Kwargs):4     ... 5     url = reverse ('article', kwargs=Kwargs)6         Print  (URL)7...     

3, distribute to the app's URLs, such as:

 1  from  django.urls import  path,include #   import include  2  3  urlpatterns = [ 4  path ("  admin/ "  , Admin.site.urls ),  5  path ( '  app1/ " , include ( " app1.url   " ))  6 ] 

When you visit a URL that looks like address/app1/xxx, it goes into App1-url.py to find Urlpatterns
