Django查询过滤器，如果attr delete为false则返回对象（即如果尚未删除）

Question

我有以下内容：

PHONE_CHOICES = (
    ('home', 'Home'),
    ('home2', 'Home 2'),
    ('mobi', 'Mobile'),
    ('mobi2', 'Mobile 2'),
    ('work', 'Work'),
    ('work2', 'Work 2'),
)

phones = []
for k, v in PHONE_CHOICES:
    try:
        phones.append(ClientPhone.objects.filter(client=clientKEY, phone_type=k).latest('id'))
    except ClientPhone.DoesNotExist:
        pass

我在ClientPhone中也有一个名为deleted的属性。如果phones为空，我只希望将最新电话附加到deleted列表。

告诉你的问题有点困难，但我想你想要这样的事情：

phones = []
for k, v in PHONE_CHOICES:
    try:
        current = ClientPhone.objects.filter(client=clientKEY, phone_type=k)
        if current.deleted is None:
            phones.append(current.latest('id'))
    except ClientPhone.DoesNotExist:
        pass
