Django implements addition, deletion, modification and query based on class view

Step 1: Import View

from django.views import View

Step 2: Create this base class

class CLS_executer(View):
    db = DB_executer

    def get(self, request):
        executer_list = list(self.db.objects.all().values())
        return HttpResponse(json.dumps(executer_list), content_type='application/json')

    def post(self, request):
        data = json.loads(request.body)
        self.db.objects.create(**data)
        return self.get(request)

    def put(self, request):
        data = json.loads(request.body)
        self.db.objects.filter(id=int(data['id'])).update(**data)
        return self.get(request)

    def delete(self, request):
        id = request.GET['id']
        self.db.objects.filter(id=int(id)).delete()
        return self.get(request)

Step 3: Set up the class view mapping in urls.py

urlpatterns = [
    path('executer/', CLS_executer.as_view())
]

Step 4: Verification

The get method directly requests the browser: {server ip: port number}/executer. Post, put, and delete can be verified with postman.
