I tried something like:
@hybrid_property
def time(self):
return self._time or self.event.time
@time.expression
def time(cls):
return case([(cls._time != None, cls

Hi at all,
I haven't found something by googling, but I'm also not sure about the
right search terms, so I hope some can help me here.
I have a model like this:
class Parent(DeclarativeBase):
id = Column(Integer, primary_key=True)
time = Column(Float)
another_id = Column(Integer)
cl
