I am having one issue .....

I want to save multiple object in a single post request ....

Here is my view

class MovieTicketCreateView (CreateAPIView):

    queryset = models.Ticket.objects.order_by('id').all()
    serializer_class = TicketSerializer

    def perform_create(self, serializer):
        details = self.request.data.get('details')
        movie_id = self.kwargs.get('movie_id')
        query = get_object_or_404(Movie, object_id=movie_id)
        for each in details:
            if each['seat']:
                seats = Seat.objects.get(id = each['seat'])
            serializer.save(movie=query, question= seats ,start_time = each['start_time])

In this view if I am creating ticket for one person its saving successfully.... But if I am creating ticket for more than one person only last details is saving ....How to save multiple object in this case

You're overriding the wrong method. You should override the create method as most of the create actions are done there while the perform_create saves the object in DB. You can do something like this:

def create(self, request, *args, **kwargs):
    movie = get_object_or_404(Movie.objects.all(), object_id=self.kwargs['movie_id'])
    for row in request.data['details']:
        row['movie'] = movie
        serializer = self.get_serializer(data=row)
        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)

Of course, you will need to adapt this solution to your input data structure as I don't know how exactly it is structured.
