Django REST framework post array of objects

Question

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 think I can send them together in an array and do this in one request.

I receive wrong input error when I'm trying to add more than one object from the REST framework web interface. I am passing objects or array of objects like below:

// this { "text": "gdhg", },{ "text": "gdhg", },{ "text": "gdhg", }
// or this [{ "text": "gdhg", },{ "text": "gdhg", },{ "text": "gdhg", }]

But I receive ParseError. Where I am wrong and what do I have to change to fix this?

Another example that supports posting an array as well as posting a single object. Might be useful for anyone else looking for such an example.

class BookViewSet(mixins.CreateModelMixin, mixins.ListModelMixin, viewsets.GenericViewSet):
    """
    ViewSet create and list books

    Usage single : POST
    {
        "name":"Killing Floor: A Jack Reacher Novel", 
        "author":"Lee Child"
    }

    Usage array : POST
    [{  
        "name":"Mr. Mercedes: A Novel (The Bill Hodges Trilogy)",
        "author":"Stephen King"
    },{
        "name":"Killing Floor: A Jack Reacher Novel", 
        "author":"Lee Child"
    }]
    """
    queryset = Book.objects.all()
    serializer_class = BookSerializer
    search_fields = ('name','author')

    def create(self, request, *args, **kwargs):
        """
        #checks if post request data is an array initializes serializer with many=True
        else executes default CreateModelMixin.create function 
        """
        is_many = isinstance(request.data, list)
        if not is_many:
            return super(BookViewSet, self).create(request, *args, **kwargs)
        else:
            serializer = self.get_serializer(data=request.data, many=True)
            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)
