Django request array or not

Question

How can I find out that incoming request is a array or not? For now I'm doing this approach

def create(self, request, *args, **kwargs):
    serializer = self.get_serializer(data=request.data)
    if isinstance(request.data, list):
        serializer = self.get_serializer(many=True, data=request.data)

What could be the best way?

One way to simplify this could this approach:

def create(self, request, *args, **kwargs):
    is_many = isinstance(request.data, list)
    serializer = self.get_serializer(many=is_many, data=request.data)

In this example, I'm assuming that by not passing many in the first function call, it defaults to False.

Since you will always run the test isinstance, might as well call it first and use that as the value for the many parameter.

This way you only ever call the self.get_serializer once.

Thank you. I did this serializer = self.get_serializer(many=isinstance(request.data, list), data=request.data)
