URLS:

from django.contrib import admin
from django.urls import path
from cmbd import views


urlpatterns = [
    path('admin/', admin.site.urls),
    path('home/', views.Home.as_view()),
]

VIEWS:

from django.shortcuts import render,redirect
from django.shortcuts import HttpResponse
# Create your views here.
from django.views import View
class Home(View):
    def dispatch(self, request, *args, **kwargs):
        print('before')
        result = super(Home,self).dispatch(request,*args,**kwargs)
        print('after')
        return result
    def get(self,request):
        print('in get')
        return render(request,'home.html')
    def post(self,request):
        print('in post')
        return render(request,'home.html')

TEMPLATES下home.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div>
        <form action="/home/" method="post">
            <input type="text" name="user" />
            <input type="submit" value="submit" />
        </form>
    </div>
</body>
</html>
