Question

我有一个User对象和一个Connection对象来管理用户之间的连接。

class User:
    username = models.CharField(max_length=100,)

和

class Connection:
    user = models.ForeignKey(User)
    friend = models.ManyToManyField('self', related_name="_friends", symmetrical=True)
    followers = models.ManyToManyField('self', related_name="_followers", symmetrical=False)
    following = models.ManyToManyField('self', related_name="_following", symmetrical=False)

我不确定如何在此建模中添加朋友。

user.connection_set._friends.add(target) -> does this work?

有人可以帮我吗？

使用OneToOne（我想您的用户只有一个与多个关注者，朋友等的连接？）

如果您使用FK或m2m字段，则需要再一步找到要使用的连接（例如User.objects.get（XXXX）.connection.get（XXXX）

class User:
    username = models.CharField(max_length=100,)

class Connection:
    user = models.OneToOneField(User)
    friend = models.ManyToManyField('self', related_name="_friends", symmetrical=True)
    followers = models.ManyToManyField('self', related_name="_followers", symmetrical=False)
    following = models.ManyToManyField('self', related_name="_following", symmetrical=False)


user = User.objects.last()
user_to_add = User.objects.first()
user.connection.followers.add(user_to_add)

在Django中建模用户到用户的连接
