Question

当新用户注册后，我有以下信号可用于创建个人资料，然后向管理员发送电子邮件，通知他们新用户

@receiver(post_save, sender=User)
def create_user_profile(sender, **kwargs):
    '''Create a profile for a new user'''
    if kwargs['created']:
        Profile.objects.create(user=kwargs['instance'])


@receiver(post_save, sender=User)
def notify_admin(sender, instance, created, **kwargs):
    '''Notify the administrator that a new user has been added.'''
    if created:
        subject = 'New Registration created'
        message = 'A new candidate  %s has registered with the site' % instance.email
        from_addr = 'no-reply@example.com'
        recipient_list = ('admin@example.com', )
        send_mail(subject, message, from_addr, recipient_list)

我希望在配置文件更新时也通知管理员，但仍在努力提出解决方案。

有什么想法吗？

Answer 1

方法-1
正如@Ralf所说，对 Profile 模型使用不同的信号并检查created标志

@receiver(post_save, sender=Profile)
def profile_update_signal(sender, instance, created, **kwargs):
    # Profile update signal
    if not created:
        # do something here <<<<<<
        send_mail()

方法-2 覆盖 save() 模型的 Profile 方法

class Profile(models.Model):
    # your fields
    def save(self, *args, **kwargs):
        if self.pk:  # not a new object
            # do something here <<<<<<
            send_mail()
        super(Profile, self).save(*args, **kwargs)

现有个人资料上的Django个人资料更新
