If you get an exception, the “except” clause will drop down into the “return” statement, and classification_serializer will be referenced before it’s assigned to. (Because it never was assigned to.) John > On Apr 22, 2015, at 2:36 PM, Cristian Javier Martinez >

You can survey technologies you don’t use in your daily work. You can explore alternative technologies for your current job. You can learn new details about technologies you know, in intermediate or advanced tutorials. You can learn in-depth, because you’re in a session for 3 hours, vs. 45

When we run the development server locally, we often start with an already-existing database. We don't re-initialize the db unless we have to, because there's been a schema change or a change in the value stored in a table's field. So we'd need SECRET_KEY to not change most of the time! John

Implementing User login expiration

I have a Profile table that's 1:1 with the User table. Each Profile row has an account_expiration field. I want to invalidate users when their accounts expire. By "invalidate", I mean: They can't log in, and they can't use the system any more. The closer I look, the more complicated it seems.
