This might be a good opportunity to make an explicit contract on default fields with respect to migration and backward compatibility, namely that default fields are subject to change, so if it's important that a field not be subject to change, the developer must make it explicit, and not assume that the default is forever. A second condition might be that any change will be safely migratable (for example, a field's default length will never be shortented). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "web2py-users" group.
