我已经设置好模块,当我去运行class supplies(models.Model): ... @property def quantity(self): data = self.kitsupplies_set.aggregate(Sum('quantity')) return data['quantity__sum'] 时,出现以下错误:(verify 'citizen)
class supplies(models.Model): ... @property def quantity(self): data = self.kitsupplies_set.aggregate(Sum('quantity')) return data['quantity__sum']
(verify 'citizen)
这是什么意思?
