How do I add a function to a model that doesn't require a model instance?

Question

So I've been trying to add a model function in Django that takes arguments and then inserts X number of new records into the database.

Why isn't it possible to do MyModel.MyFunction()? Do I need to make an instance of it first?

If so, is there a better way of achieving the result I desire?

Answer 1

You can certainly do this, you just need to make it a classmethod:

class MyModel(models.Model):
    @classmethod
    def my_function(cls):
        new_instance = cls(...)
        new_instance.save()
        # etc...
