我有一个具有相同要求的 django 应用程序。这是我对其建模的方式（当然没有“正确”的方式，这取决于您的应用程序的需求）：

class User(models.Model):
    number = models.CharField(max_length=24)
    name = models.CharField(max_length=128, blank=True, null=True)
    email = models.CharField(max_length=64, blank=True, null=True)
    ...

class Group(models.Model):
    name = models.CharField(max_length=128)
    owner = models.ForeignKey(User)   
    members = models.ManyToManyField(User, through='Membership', related_name='members', blank=True, null=True)
    ...

class Membership(models.Model):
    # You can add other statuses depending on your application's needs
    STATUS_SUBSCRIBED = 0
    STATUS_UNSUBSCRIBED = 1
    STATUS_REQUESTED = 2

    STATUS = (
    (STATUS_SUBSCRIBED, 'Joined'),
    (STATUS_UNSUBSCRIBED, 'Unsubscribed'),
    (STATUS_REQUESTED, 'Requested'),
    )

    user = models.ForeignKey(User)
    group = models.ForeignKey(Group)
    status = models.IntegerField(choices=STATUS)

    added = models.DateTimeField(auto_now_add=True)
    last_updated = models.DateTimeField(auto_now=True)
