django信号don'；不要给我发通知

我有下一个带信号的型号：

class ParticipantModel(models.Model):
    TYPE_USER = (
        ('O', 'Онлайн трансляция'),
        ('P', 'Персональное присутствие'),
    )

    name = models.CharField( max_length=256, verbose_name='Имя')
    surname = models.CharField(max_length=50, verbose_name='Фамилия')
    position = models.CharField(max_length=50, verbose_name='Должность')
    company = models.CharField(max_length=50, verbose_name='Название компании')
    city = models.CharField(max_length=50, verbose_name='Город')
    email = models.EmailField(verbose_name='Электро почта')
    phone = models.CharField(max_length="50", verbose_name="Телефон")
    phonem = models.CharField(max_length="50", verbose_name="Мобильный телефон")
    www = models.URLField(verbose_name="Сайт")
    tuser = models.CharField(max_length='250', choices=TYPE_USER, verbose_name="Форма вашего участия")

    class Meta:
        verbose_name = ('Участник')
        verbose_name_plural = ('Участники')


def send_marketing(sender, instance, created, **kwargs):
    if created:
        message = "New participant"
        subject = "Updates"
        from_email = 'bakotech.events@gmail.com'
        recipient_list = ('sergey@avetisyan.com.ua')
        send_mail(subject, message, from_email, recipient_list)

    post_save.connect(send_marketing, sender=ParticipantModel)

我的电子邮件后端配置：

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'bakotech.events@gmail.com'
EMAIL_HOST_PASSWORD = '********'
EMAIL_PORT = 587

---

我希望在模型保存到数据库后，我必须收到关于它的通知的电子邮件

在调用post_save之前删除缩进-这需要在导入模块时调用，而不是在信号函数内调用！）

似乎您在

post\u save.connect…

Hi Andrey，感谢您的回复）之前添加了过多缩进，但我想我们可以谈谈俄语。缩进出现是因为我在复制/粘贴代码块时出错。谢谢，我删除了很多，但没有任何改变，我仍然犯了这个错误。当我更改收件人列表=（'sergey@avetisyan.com.ua“）收件人列表=（”sergey@avetisyan.com.ua这个错误我被这个家伙指了指
