my model has field should change if it's within date range. it this: class election(models.model) start_date = models.datetimefield(verbose_name = 'start date') end_date = models.datetimefield(verbose_name = 'end date') active = models.booleanfield(default=false) def updateactive(self): = timezone.now() if self.start_date < , self.end_date > now: self.active=true else: self.active=false self.save() right now, every time query model, call updateactive() views.py . so, question is: there way call updateactive() every time fetch election object? or keeping constant updated? any idea welcome. the best method not have active field @ in model. main reason when value can generated simple calculation, should not stored in database. second reason booleanfield cannot indexed , queries involving field slow. therefore not lose doing calculation instead of doing field. best
