想要follow()
在 UserProfile 中调用函数时使用信号。我已经编写了可与其他模型一起使用的信号(保存时)。
class UserProfile(UserenaBaseProfile):
user = models.OneToOneField(User,unique=True,verbose_name=_('user'))
location = models.CharField(_('Location'), max_length=255, blank=True, default='')
following = models.ManyToManyField(User, verbose_name=_('following'), related_name='followers', blank=True, null=True)
def follow(self, user):
self.following.add(user)
def unfollow(self, user):
self.following.remove(user)
信号
def follow_action(sender, instance, created, action_object=None, **kwargs):
action.send(instance.user, verb='follows', target=instance.content_object)
post_save.connect(follow_action, sender=UserProfile)
此信号在UserProfile
模型保存时有效。我想在follow()
函数执行时调用信号。你能帮忙吗?任何的想法?多谢
更新:
def follows_action(sender, instance, created, action_object=None, **kwargs):
action.send(instance.user, verb='follows', target=instance.content_object)
m2m_changed.connect(follows_action, sender=UserProfile.following.through)
这没用。我错过了什么吗?
