When i'm trying simply get some objects from db i getting error: 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 made some changes in my model properties, and just trying to migrate data to new schema. And why Get() method checks required option of property? If i had old objects with such property with Null value, before i set require option, i can no get this object after update, because i'll have error required field error. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
