Django - 如何查询与"列表"对象关联的所有用户

Question

我的模型看起来像这样:

• CustomUser与"Listing"对象有很多关系

• 每个Listing对象都有一个"author"字段

  author = models.ForeignKey(CustomUser)
  

• 从本质上讲,列表包含作者(CustomUser)和需要确认的自定义用户.

我正在尝试获取所有需要确认作者发布的所有列表的自定义用户.

我不确定查询的正确方法是什么.

Listing.objects.filter(author=author).needsConfirmation_set.all()

模特

class CustomUser(models.Model):
    user = models.OneToOneField(User)
    location = models.CharField(max_length=50)
    rating = models.FloatField(null=True)
    level = models.CharField(max_length=50)
    followers = models.ManyToManyField("self", related_name="followers")
    following = models.ManyToManyField("self", related_name="following")
    interested = models.ManyToManyField('Listing', related_name = 'interested', default=None)
    needsConfirmation = models.ManyToManyField('Listing', related_name = 'needsConfirmation', default=None)
    confirmed = models.ManyToManyField('Listing', related_name = 'confirmed', default=None)

class Listing(models.Model): 
    subject = models.CharField(max_length=42)
    location = models.CharField(max_length=50, default="N/A")
    description = models.CharField(max_length=500)
    author = models.ForeignKey(CustomUser)
    date = models.DateTimeField(default=timezone.now)

Answer 1

我认为这很简单:

CustomUser.objects.filter(needsconfirmation__author=author)
