Django Rest Framework not creating model tables in test DB?

Question

Django

Wrote a test for adding and getting a model.

class PatientTests(APITestCase):

    def test_create_patient(self):
        url = reverse('patient-list')
        data = {'firstname': 'ivan', 'lastname': 'ivanov'}
        response = self.client.post(url, data)
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(Patient.objects.count(), 1)
        self.assertEqual(Patient.objects.get().firstname, 'ivan')

    def test_get_patient(self):
        url = reverse('patient-detail', args=[1])
        response = self.client.get(url)
        self.assertEqual(response.data, {'firstname': 'ivan'})

I launch, as a result:
In the console, the creation of a test database passes, then the error django.db.utils.ProgrammingError: relation "patient" does not exist falls. How to overcome this problem? I so understand in a test DB which in storage the given table is not created?
