Yes, that was I wanted. This case like I know you, but you don't know me.

related_name_set object, so I can write code like this.
def all_group(user):
groups = []
for group in user.group_set.all():
if not group in group

Alex, thank you very much.
I find if g1 belong g2, g2 will belong g1 automatically, but that is not right.

groups = models.ManyToManyField('self', symmetrical=False)

class user(models.Model):

class group(models.Model):
groupname = models.CharField(max_length=50)
users = models.ManyToManyField(user)
groups = models.ManyToManyField('self')

I have no idea to get a complete group li

I want design a group that can contain other groups, and one group can
belong many groups.

class Group(models.Model):
groups = models.ManyToManyField(Group)
any suggestion?
or how to design such a group.
thanks.
