Comment:
The `AttributeError` is not raised. This test fails as the
`assertRaisesMessage()` call:
{{{
class Tests(TestCase):
def test_attribute_error_stops_save(self):
my_model_args = { 'worthless_field' : '2019-02-07'}
myExceptionalModel = MyModel( **my_model_args)
msg = "'str' object has no attribute 'isoformat'"
with self.assertRaisesMessage(AttributeError, msg):
myExceptionalModel.save()
self.assertEqual(0, MyModel.objects.count())
}}}
Behaviour is as expected:
{{{
>>> myExceptionalModel.save()
>>> myExceptionalModel.refresh_from_db()
>>> myExceptionalModel.worthless_field
datetime.date(2019, 2, 7)
}}}
Sample app with model and test case attached.
