我有一个带有外键帐户的分支模型（分支的所有者）：

class Branch(SafeDeleteModel):
    _safedelete_policy = SOFT_DELETE_CASCADE
    name = models.CharField(max_length=100)
    account = models.ForeignKey(Account, null=True, on_delete=models.CASCADE)
    location = models.TextField()
    phone = models.CharField(max_length=20, blank=True,
                         null=True, default=None)
    create_at = models.DateTimeField(auto_now_add=True, null=True)
    update_at = models.DateTimeField(auto_now=True, null=True)

    def __str__(self):
        return self.name

    class Meta:
        unique_together = (('name','account'),)

    ...

我有一个带有用户外键的帐户模型（一对一字段）：

class Account(models.Model):
    _safedelete_policy = SOFT_DELETE_CASCADE
    name = models.CharField(max_length=100)
    user = models.OneToOneField(User)
    create_at = models.DateTimeField(auto_now_add=True)
    update_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name + ' - ' + self.create_at.strftime('%Y-%m-%d %H:%M:%S')

我为分支创建了ModelViewSet，它显示了登录用户拥有的分支：

class BranchViewSet(viewsets.ModelViewSet):
    serializer_class = BranchSerializer
    permission_classes = (permissions.IsAuthenticated,)
