Hi guys I'm revisiting this issue. I really don't like the work around I suggested above. Also, I'm having to revisit some live code which will be a real headache to refactor the m2m logic into o2m + m2o.
A new work around I'm thinking of is as follows: 1. Add customer methods for getters and setters for the extra columns I need to access. 2. Add a decorator with a configure() method which queries the DB with the Id of the current object and gets the extra column values in the m2m table. 3. Within the configure() call each customer setter. Is it a bad idea due to have SQL query in a decorator configure method? I assume it will only be called once per object. I know the columns won't be saved when I call the save() method however various triggers on the database populate these fields anyway.
