如何在 Django 中两次在查询中使用过滤器

Question

我正在尝试使用此查询过滤一些数据，

get_members = PaymentDetails.objects.filter(participants_name=Participants.objects.filter(participants_name=Profile.objects.get(user=request.user)))

但我收到此错误精确查找的 QuerySet 值必须限制为使用切片的一个结果。我的模型看起来像这样

class Committee(models.Model):
    committee_creator = models.ForeignKey(Profile, on_delete=models.CASCADE)
    committee_name = models.CharField(max_length=100)

class Participants(models.Model):
    participants_name = models.ForeignKey(Profile, on_delete=models.CASCADE)
    participants_committee_name = models.ForeignKey(Committee, on_delete=models.CASCADE)
   
class PaymentDetails(models.Model):
    participants_name = models.ForeignKey(Participants, on_delete=models.CASCADE)
    participants_paid_status = models.BooleanField(default=False)
    participants_amount_paid = models.IntegerField()

Answer 1

试试这个我会假设你在User和Profile之间有OneToOne关系。

get_members = PaymentDetails.objects.filter(participants_name__participants_name_id = request.user.profile.pk)
