Hi All,
If I have an unmapped object which has had some attributes set on it, what
would be the best way to use that object to load a mapped object?
I didn't noticed a session.lookup(myobj) method ;-)
what is it looking up ? what's a "myobj" ?
An unmapped instance of the mapped class.
Here's a unit test I'd like to have pass, although in this example
lookup is implemented as a method on the mapped class:
class LookupTests(TestCase):
def setUp(self):
Base = declarative_base()
class Model(Common, Base):
id = Column(Integer, primary_key=True)
value1 = Column(Integer, nullable=False)
value2 = Column(Integer, default=42)
self.Model = Model
registerSession(metadata=Base.metadata)
def test_simple(self):
session = getSession()
model1 = session.add(self.Model(id=1, value1=2, value2=3))
model2 = Model(value1=2).lookup(session)
self.assertTrue(model2 is model1)
cheers,
Chris
