Testing MPTT models¶
Using testing generators¶
Using testing generators such as
model_bakery is causing random tree fields values, which can cause unexpected behavior.
To prevent that the
django-mptt.MPTTModel will throw an Exception if made through model_mommy/model_bakery in test environment unless
MPTT_ALLOW_TESTING_GENERATORS setting is set to True.
You can set the
MPTT_ALLOW_TESTING_GENERATORS setting to True in your Django testing settings.py file or by the
@override_settings decorator for particular test.
You would probably also have to use recipe and explicitly set the appropriate fields for the model.
from django.test import override_settings from baker.recipe import Recipe @override_settings(MPTT_ALLOW_TESTING_GENERATORS=True) def test_mptt_allow_testing_generators(self): my_model_recipe = Recipe(MyMPTTModel, lft=None, rght=None) test_model_instance = my_model_recipe.make()
