我正在尝试设置 django 信号，让某人在创建博客后受到关注

Question

但此代码不起作用...在 /blog/create/

保留类似“TypeError”的错误消息

这是我放在 blog/signals.py

的代码

@receiver(signals.post_save, sender=Post)
def send_mail(sender, instance, created, **kwargs):
    print('signal send')

    subject = "Thank you"
    message = Post.objects.get(??)
    send_mail(subject, 'message', '',
              ['info@*****.com.au'], fail_silently=False, )

??是这个问题...我放pk=pk,pk=id,不知道这里需要放什么参数...

Answer 1

您不需要显式获取 Post，您已经将其作为发送到信号的 instance 参数（根据 docs）：

instance
The actual instance being saved.
