Django ManyToManyField排序使用through

我刚刚经历了这个。

class Profile(models.Model):         accounts = models.ManyToManyField('project.Account',     through='project.ProfileAccount')    def get_accounts(self):        return self.accounts.order_by('link_to_profile')class Account(models.Model):    name = models.CharField(max_length=32)class ProfileAccount(models.Model):    profile = models.ForeignKey('project.Profile')    account = models.ForeignKey('project.Account', related_name='link_to_profile')    number = models.PositiveIntegerField()    class meta:        ordering = ('number',)

我删除了除之外没有主题的字段

Account.name
