Q:

How to create a django User using DRF's ModelSerializer

In django, creating a User has a different and unique flow from the usual Model instance creation. You need to call create_user() which is a method of BaseUserManager.
Since django REST framework's flow is to do restore_object() and then save_object(), it's not possible to simply create Users using a ModelSerializer in a generic create API endpoint, without hacking you way through.
What would be a clean way to solve this? or at least get it working using django's built-in piping?
Edit:
Important to note that what's specifically not working is that once you try to authenticate the created user instance using django.contrib.auth.authenticate it fails if the instance was simply created using User.objects.create() and not .create_user().

A:

Eventually I've overridden the serializer's restore_object method and made sure that the password being sent is then processes using instance.set_password(password), like so:
def restore_object(self, attrs, instance=None):
    if not instance:
        instance = super(RegisterationSerializer, self).restore_object(attrs, instance)
    instance.set_password(attrs.get('password'))
    return instance

Thanks everyone for help!
