I am using Django REST framework for API and Angular SPA with Restangular to communicate with the API. Sometimes, I have to add more than one object using the API and I thin

If you want to post a list you have to pass in JSON encoded data.

headers = {"Token": "35754sr7cvd7ryh454"}

recipients = [{'name': 'Ut est sed sed ipsa', 
               'email': 'dogoka@mailinator.com', 
               'group': 'signers'},
              {'name': 'Development Ltda.', 
               'email': 'test@test.com',
               'group': 'signers'}
             ]

requests.post(url, json=recipients, headers=headers)

requests.post(url, json=recipients, headers=headers)

Use json keyword argument (not data) so the data is encoded to JSON and the Content-Type header is set to application/json.

By default, Django Rest Framework assumes you are passing it a single object. To serialize a queryset or list of objects instead of a single object instance, you should pass the many=True flag when instantiating the serializer. You can then pass a queryset or list of objects to be serialized.

To do it, you'll have to override the .create() method of your view:

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

    serializer = self.get_serializer(data=request.data, many=many)
    serializer.is_valid(raise_exception=True)
    self.perform_create(serializer)
    headers = self.get_success_headers(serializer.data)
    return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)
