This is strange. We do this:
DBSession = scoped_session(sessionmaker(
autoflush=True,
autocommit=False,
))
And we use it directly as this:
def test_documents(self):
immutable = db.Immutable(uid=random_uid(), mime_type="LiveSet",
size=100000)
imm_child = db.Immutable(uid=random_uid(), mime_type="FLAC",
size=100000)
immutable.children.append(imm_child)
DBSession.flush() #...@undefinedvariable
I can't tell you why the direct use doesn't work. But what for sure is
wrong is to instantiate the session in __init__ - because that creates
*one session to rule them all* - which won't work. You don't want only
one global transaction for the whole lifetime of your program...
Try then instantiating the session on demand - e.g. in controllers.
