[Zope3-Users] Plugin postgres storage replacement for ZODB

[andrew]

Hi All,

This might be a long shot, but it's worth a try :-) I'm looking to build
a zope3 application that requires standard user management,
authentication, etc., but I want to store all persistent data in a
Postgres database rather than the ZODB. The reason is that I want to be
able to do ad-hoc indexed queries on a given set of attributes across
all, e.g., user objects in the database, and (AFAIK) an object database
just won't cut it.

However, I don't want to have to rewrite a whole lot of ORM code so is
there something out there that will take a given collection of objects
and automatically map them to a relational database table ? I'm thinking
of something on the level of a plugin replacement for ZODB and using a
framework like Grok or z3ext, because I just want to prototype this
relatively quickly.

Does that sound doable ? Anyone done this before ?

Cheers, Andrew.
