For some columns I want to process it a bit before getting or setting it.
For example, I have a column Status, but have to call it _Status to avoid
name conflict with its property.
class Task(Base):
_Status = Column('Status')
@property
def Status(self):
return f(self._Status)
@Status.setter
def Status(self, value):
self._Status = value
Now whenever I write a query involving Status I must remember to use
_Status. If I accidentally use Status in a query, it adds WHERE 0 = 1, thus
returning nothing, so it fails and I don't know why.
I'm converting from SQLObject where you can call the column Status and
define getter and setter by defining functions _get_Status and _set_Status.
When I access Status in a query SQLObject knows to use the Column and
outside a query it uses _get_Status.
How can I get this behaviour with SQLObject?
