This would probably be close to what I would write for my usecase:
class Database:
implements(IDatabase)
def __init__(self, *args, **kw):
self._args = args
self._kw = kw
def scopefunc(self):
return None # use default per-thread scoping
def session_factory(self):
return sessionmaker(*self._args, **self._kw)
I don't think you can use sessionmaker, as that creates a class and you
need to create an actual session in this place. You'd need
create_session. You'd also need to implement your scopefunc, otherwise
you get *no* scoping at all, not even per thread, so return
thread.get_ident().
Like this:
class Database:
implements(IDatabase)
def __init__(self, *args, **kw):
self._args = args
self._kw = kw
def scopefunc(self):
return thread.get_ident()
def session_factory(self):
return create_session(*self._args, **self._kw)
we're ignoring the details of what creates the engine, but if you pass
'bind' along when you create Database that should take care of it.
