The example "Prefetching for model properties and methods" does not work

[Jakuje]

When I want to define hints for the @property on a model class, the model is not yet defined so Python (tested with 3.8) complains:

NameError: name 'Person' is not defined

django-virtual-models/docs/tutorial.md

Lines 571 to 590 in 2eda0c0

	from django_virtual_models import hints
	class Person(models.Model):
	name = models.CharField(max_length=255)
	@property # <--- property must come before
	@hints.no_deferred_fields()
	def name_title_case(self):
	return self.name.title()
	# method w/o params, DRF supports that too:
	def has_won_any_award(self: Annotated[Person, hints.Virtual("awards")]):
	return len(person.awards) > 0
	class PersonSerializer(v.VirtualModelSerializer):
	class Meta:
	model = Person
	virtual_model = VirtualPerson
	fields = ["name_title_case", "has_won_any_award"] # <--- this works
