How do I create multiple model instances with Django Rest Framework?

I would like to save and update multiple instances using the Django Rest Framework with one API call. For example, let's say I have a "Classroom" model that can have multiple "Teachers". If I wanted to create multiple teachers and later update all of their classroom numbers how would I do that? Do I have to make an API call for each teacher?

I know currently we can't save nested models, but I would like to know if we can save it at the teacher level. Thanks!

I know this was asked a while ago now but I found it whilst trying to figure this out myself.

It turns out if you pass many=True when instantiating the serializer class for a model, it can then accept multiple objects.

This is mentioned here in the django rest framework docs

For my case, my view looked like this:

class ThingViewSet(viewsets.ModelViewSet):
    """This view provides list, detail, create, retrieve, update
    and destroy actions for Things."""
    model = Thing
    serializer_class = ThingSerializer

I didn't really want to go writing a load of boilerplate just to have direct control over the instantiation of the serializer and pass many=True, so in my serializer class I override the __init__ instead:

class ThingSerializer(serializers.ModelSerializer):
    def __init__(self, *args, **kwargs):
        many = kwargs.pop('many', True)
        super(ThingSerializer, self).__init__(many=many, *args, **kwargs)

    class Meta:
        model = Thing
        fields = ('loads', 'of', 'fields', )

Posting data to the list URL for this view in the format:

[
    {'loads':'foo','of':'bar','fields':'buzz'},
    {'loads':'fizz','of':'bazz','fields':'errrrm'}
]

Created two resources with those details. Which was nice.

I came to a similar conclusion as Daniel Albarral, but here's a more succinct solution:

class CreateListModelMixin(object):

    def get_serializer(self, *args, **kwargs):
        """ if an array is passed, set serializer to many """
        if isinstance(kwargs.get('data', {}), list):
            kwargs['many'] = True
        return super(CreateListModelMixin, self).get_serializer(*args, **kwargs)
