You can overwrite save() method in your model to return a model instance after saving an object, for example:
class YourModel(models.Model):
name = models.CharField(max_length=20)
def save(self, *args, **kwargs):
super(YourModel, self).save(*args, **kwargs)
return self
your_model_saved_instance = YourModel(name='example').save()
Then you will receive an instance from the user class instead of the form class
user = user.save()
