django - 可以仅使用实例 ID 添加到 Django ManyToManyField

Question

当您只有 ID 列表而没有数据库命中来检索实例时，是否可以添加到 ManyToManyField(add_instances_but_with_db_hit 可以执行此操作，但需要命中)。

谢谢。

class WorkerCombinedPayment(AbstractReimbursement):
    charge_id = models.TextField(blank=True, null=True)
    paid = models.BooleanField(default=False)
    worker = models.ForeignKey(Worker)

class MassPayment(TimeStampedModel):
    list_payments = JSONField(blank=True, null=True)
    paypal_batch_id = models.TextField(blank=True, null=True)
    success = models.NullBooleanField()
    response_from_paypal = JSONField(blank=True, null=True)
    workercombinedpayments = models.ManyToManyField(WorkerCombinedPayment)

    def add_instances_but_with_db_hit(self, id_list):
        found = WorkerCombinedPayment.objects.filter(id__in=id_list)
        self.workercombinedpayments.add(found)

Answer 1

是的，您只需传递 ID 即可:

self.workercombinedpayments.add(*id_list)
