嗨，伙计，我是 Django 的新手。什么可能导致这个例外？请帮帮我。

模型.py

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)

表格.py

class ParticipantForm(forms.ModelForm):

class Meta(object):
    model = ParticipantModel

视图.py

class CreateParticipant(CreateView):
    form_class = ParticipantForm
    template_name = 'registraition.html'
    success_url = '/'


    def form_valid(self, form):
        VendorModel.objects.create(**form.cleaned_data)
        return redirect(self.get_success_url())

这个错误是在我将信号建模后出现的。我不知道该怎么做才能在 django 学习中前进以及在哪里挖掘答案。在我改变观点之后

def form_invalid(self, form):
    VendorModel.objects.create(**form.cleaned_data)
    return redirect(self.get_success_url())

我发现了另一个错误而不是这个：

改变

recipient_list = ('sergey@avetisyan.com.ua')

至

recipient_list = ('sergey@avetisyan.com.ua', )

或者

recipient_list = ['sergey@avetisyan.com.ua']

('sergey@avetisyan.com.ua')仍然是一根()缠绕着它的绳子。对于 python 将其解释为元组，您需要,, 作为requires a或 a 的to参数send_mailtuplelist
