Hello, list! Hello, Ramsey!
I want to implement ERCAuditTrail from Ponder (ERCoreBL framework, not
ERCoreBusinessLogic) in a new app.
Searching through the archives, I’ve found this:

I have some questions:
1. Is this the way to do it? Has something changed from 2012?
2. Dieter says “[r]un migrations or add the relevant tables to DB”. If my app
migrates automatically on startup, do I still need to do this?
3. Does the UserEntity have to be a subclass of ERUser?
Cheers,
Flavio
