Hi all, Say I have this simple model:
DayTimesheet date: a Date entries: a list of TimeEntry TimeEntry: day: a DayTimesheet in: a time (HH:MM) out: a time (HH:MM) DayTimesheet is the parent of TimeEntry in a one-to-many relationship. What would be the best way of ensuring the following: 1. Creating DayTimesheet on demand, i.e. DayTimesheet.get_by(date=nonexistentdate) would create a new instance if needed (inserted on the next flush()) and 2. Automatically removing childless DayTimesheet instances - that is, when the last TimeEntry is deleted from a DayTimesheet, delete the DayTimesheet too?
