As far as I could understand the SQLAlchemy docs (especially [1], some kind
of a centralised session handling is a must have, as the current habit of
defining a DBSession = scoped_session actually create separate session
factories, and only the session provided by each of these are the same.
That

I'm no SQLAlchemy expert but out of curiosity, why can't there be a

sqlahelpers tried to do exactly this; but this approach makes it
impossible to provide arguments for the construction of the

to supply my own base class.

In SQLAlchemy the metadata is the central object that binds tables
together and describes their relationships. It is not possible to describe
relationships between tables that are defined using different metadata
objects. As you know already, each Base creates its own shared metadata
object
On the other hand, I'm not doing anything in my custom cls passed to
declarative_base which could not be done in a mixin class [1].

I don't see a different solution in here. It is all just an extension of
the you must share something idea. I could've explicitly pointed out all
the possible ways to inject a common metadata into the declarative base,
etc but in the end you still have a common metadata that you import/inject.
Sorry to top-post, but this is one of the reasons I wrote mortar_rdb,
writing offline from memory, the url is:
http://packages.python.org/mortar_rdb.
Anyway, have a read of the docs, it solves the
Base-shared-across-packages problem as well as providing session and
transaction management.
Hi guys,
thanks for all the info.
My goal is to reuse existing apps that might define their own Base classes,
but I would like to have foreign key relationships into many directions.
Actually, for the moment, it seems to me that ForeignKey(MyClass.id)
instead of string based
