[SOLVED] Django REST serializer: create object without saving

Django REST serializer: create object without saving

I have started to play with the Django REST framework. What I am trying to do is to POST a request with some JSON, create a Django Model object out of it, and use the object without saving it. My Django model is called SearchRequest. What I have is:

@api_view(['POST'])
def post_calculation(request):
    if request.method == 'POST':
        #JSON to serializer object
        serializer = SearchRequestSerializer(data=request.data)
        if (serializer.is_valid() == False):
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
        mySearchRequestObject = serializer.save()

This does create a SearchRequest object, however saves it into the database right away. I would need it without saving.

Solution

Add this method to your SearchRequestSerializer class:

def create(self):
    return SearchRequest(**self.validated_data)

And call it in function post_calculation instead of save, like so:

mySearchRequestObject = serializer.create()
