I have an intermediate model which I am using to keep track of which labs
to include since individual labs can be removed.
So when you add a new intermediate model (AgendaModel) it automatically
adds all of the labs.
with
@event.listens_for(Agenda.modules, 'append')
But there is a UNIQUE
I have a Many-to-Many relationship that I would like to keep track of the
order. I am wondering if I can automatically populate the module_position
field based on the current number of AgendaModule's for an Agenda.
class AgendaModule(db.Model):
__tablename__ = 'agenda_modules'
