class Thread(db.Model):
members = db.StringListProperty()
def user_is_member(self, user):
return str(user) in self.members
and
thread = Thread.get(db.Key.from_path('Thread', int(id)))
is_member = thread.user_is_member(user)
but the error is :
Traceback (most recent call last):
File "D:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 511, in __call__

is_member = thread.user_is_member(user)
AttributeError: 'NoneType' object has no attribute 'user_is_member'
why ?
