In Django, two request processing methods are available: fbv and CBV.
I. fbv
Fbv (function base views)Is to use functions in the view to process requests.
Check the Code:
URLs. py
| 12345678 | from django.conf.urls import url, include# from django.contrib import adminfrom mytest import views urlpatterns = [ # url(r‘^admin/‘, admin.site.urls), url(r‘^index/‘, views.index),] |
Views. py
| 123456789 | from django.shortcuts import renderdef index(req): if req.method == ‘POST‘: print(‘method is :‘ + req.method) elif req.method == ‘GET‘: print(‘method is :‘ + req.method) return render(req, ‘index.html‘) |
Note that the function [DEF index (req):] is defined here ):]
Index.html
| 12345678910111213 | <!DOCTYPE html> |
The above is the use of fbv.
Ii. CBVCBV (class base views)The class is used to process requests in the view.
Modify URLs. py in the above Code as follows:
| 123456 | from mytest import views urlpatterns = [ # url(r‘^index/‘, views.index), url(r‘^index/‘, views.Index.as_view()),] |
Note: URL (R' ^ index/', views. Index. as_view () is a fixed usage.
Modify views. py in the above Code as follows:
| 1234567891011 | from django.views import Viewclass Index(View): def get(self, req): print(‘method is :‘ + req.method) return render(req, ‘index.html‘) def post(self, req): print(‘method is :‘ + req.method) return render(req, ‘index.html‘) |
Note: To Inherit the view, the number of letters in the class must be in lower case.
You can use either of the two methods.
