I doubt this is possible, but SqlAlchemy supports so many oddities it might be...
I have an association class/table which has a primary key on the serial column `id`, and a unique constraint on the columns `id_a` and `id_b` which acts as a secondary key. is there a sane way to use something like `.get()` against the `(id_a, id_b)` tuple, as if it were the primary key? i.e. return a matching record if it is in the session, otherwise perform a database fetch. I'm dealing with a path of logic in which this object might be loaded by the tuple 5 times, and would like to eliminate the redundant queries, as this happens on a highly trafficked view on a webapp. I've considered using a secondary class mapped to the same table, using the tuple as the primary key. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
