in my model class, i have a synthetic property that doesn't map
directly to a table field, and it is initialized in the constructor:
class User(BaseModel):
def __init__(self):
self._pwd = ''
def get_pwd(self):
return self._pwd
def set_pwd(self, pwd):
self._pwd = pwd
self.hashed_password = User.hash_pwd(pwd)
password = property(get_pwd, set_pwd)
@classmethod
def hash_pwd(cls, pwd):
salt = r'somerandomcharacters'
return md5.new(pwd + salt).hexdigest()
so calling user.password will return the non-hashed password. this
works fine for new instances, but when i retrieve from the database
e.g.
user = session.query(User).get_by(id=1)
accessing user.password results in:
Traceback (most recent call last):
File "<console>", line 1, in ?
File "C:\home\jeffe\python\tg\claimsqa\claimsqa\model.py", line 255,
in get_pwd
return self._pwd
AttributeError: 'User' object has no attribute '_pwd'
is SA not calling __init__ or am i doing something wrong?
thanks,
jeff
