def check_notification(request):
user = request.user
profile = Person.objects.get(profile=user)
notification = NotificationRecipient.objects.filter(profile=profile)
return JsonResponse(model_to_dict(notification))

Answer 1

You can make a model Serializers for models you want to pass as response. for more information read django rest framework tutorial about serializers an learn how to make json response. Or if you have a simple dictionary you can make json response with this code snippet at the end of your check_notification function. return HttpResponse(json.dumps(your dictionary))

Answer 2

I would recommend you use Django Rest Framework for returning Responses in JSON format as the Serialization of models can be don easily. You can start from here. There you will find something known as a ModelSerializer. Basically you create a serializer.py in your app folder with the following content:
from rest_framework import serializers
from .models import Person, NotificationRecipient
class PersonSerializers(serializers.ModelSerializer):
class Meta:
model = Person
fields = '__all__'
class NotificationRecipientSerializers(serializers.ModelSerializer):
class Meta:
model = NotificationRecipient
fields = '__all__'
The above code will serialize your models which means will be converted to json format.
Than in a file named as views_api.py, you can create a class that will be called using by the URL and will have your queryset defined. In your case the class will be defined as:
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import Person, NotificationRecipient
from .serializers import NotificationRecipientSerializers
class NotificationAPIView(APIView):
def get(self,request):
user = request.user
profile = Person.objects.get(profile=user)
notification = NotificationRecipient.objects.filter(profile=profile)
return Response(notification)
This will return the response in JSON format. In your urls.py file call the NotificationAPIView as follows:
from django.urls import path
from .import views_api
urlpatterns = [
path('check/notification/', views_api.NotificationAPIView.as_view(), name='notification'),
]
Hope you get a basic understanding of what is going on there. For better understanding go through Django Rest Framework docs.
