Hello,
I'm trying to build a generic inlog service. Which uses the default DB_login_service if you are online but offline I want to check the SQLite db.
The problem is that in the example I have used: "http://docs.appery.io/tutorials/build...".
The DB_login_service returns an error and that is used to display a message.
I would like to do the same with my generic service (and any other service I'm going to build). But I cannot find any document/example/tutorial of how to generate/raise an error and how to fill that error with some information?
