raises an interesting issue and proposes an interesting solution that works on GAE. Executive summary: In GAE you can define computed fields that are computed now when data is extracted but when data is stored and the computed fields are stored too. Why? Because you can use them to perform operation that would otherwise not be supported on GAE. It would be trivial to support this in web2py and make it cross-db. Basically all we need is a new field attribute that points to a function that computes the value of a field based on the values of the other fields. We already have this db.table.field.update and it can be a function. I think the new DAL should support this.
