Hello everyone!
I am continuing with the migration from SqlAlchemy 0.6.8 to 0.7.4, and
I've seen a little difference in behavior.
I have a class Product (more or less) like:
class Product(declarativeBase):
_id = Column("id", Integer, primary_key=True)
_model = Column("model", Unicode(128))
@hybrid_property
def model(self):
return self._model
@model.setter
def setModel(self, model):
if model:
self._model = unicode(model)
else:
self._model = None
#id hybrid property as well
Both id and model are hybrid_properties now (they were Synonyms in 0.6.8)
When I query only some values:
query = session.query(Product.Product).filter(Product.Product.id ==
25).values(Product.Product.model)
for element in query:
print "%s\n" % vars(element)
The query works perfectly, but I get this:
{'_model': u'myAifon', '_labels': ('_model',)}
The "hidden" (or masked... I don't know how to call it) attribute (the
"private" one, starting with a "_") so if I try something like
for element in query:
print "The 'model' is: %s\n" % element.model
I get a "Kaboom!!" (I''ve heard it's the Swahili for AttributeError
exception). Is there a workaround this? I am trying to migrate all my
Synonyms to hybrid_properties, specially since I read "synonym() is
superseded as of 0.7 by the hybrid extension."
(http://www.sqlalchemy.org/docs/orm/mapper_config.html). That was
enough to make me obsessed with getting rid of the synonyms :-)
Thank you in advance!
