When i'm trying to do simple get() it raises error: Traceback (most recent call last): File "/base/python_lib/versions/1/google/appengine/ext/webapp/ __init__.py", line 501, in __call__ handler.get(*groups) File "/base/data/home/apps/musicvideobuger/1.332849534198860778/ video_crawler.py", line 233, in get videos = Video.all().fetch(100) File "/base/python_lib/versions/1/google/appengine/ext/db/ __init__.py", line 1391, in fetch return map(self._model_class.from_entity, raw) File "/base/python_lib/versions/1/google/appengine/ext/db/ __init__.py", line 997, in from_entity instance = cls(None, _from_entity=True, **entity_values) File "/base/python_lib/versions/1/google/appengine/ext/db/ __init__.py", line 596, in __init__ prop.__set__(self, value) File "/base/python_lib/versions/1/google/appengine/ext/db/ __init__.py", line 2581, in __set__ value = self.validate(value) File "/base/python_lib/versions/1/google/appengine/ext/db/ __init__.py", line 2611, in validate if value is not None and not value.has_key(): AttributeError: 'unicode' object has no attribute 'has_key'
It happened after i changed some of properties in model, and i can't make migration. Also why get() function checking required option of property? I had some old data with None values in properties, witch in new version had been checked as required. When i'm trying to access objects with such properties with Null values i get error that this property required, by i'm just trying to get, not put! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
