Django 使用信号发送电子邮件

Question

我正在测试 django 信号以发送电子邮件，但出现以下错误。

'list' 对象没有属性'splitlines'

@receiver(post_save, sender=Booking)

def new_booking(sender, instance, **kwargs):
if instance.firstname:
    firstname = [instance.firstname]
    # lastname = [instance.lastname]
    email = [instance.email]
    # phone = [instance.phone]
    subject = [instance.service]
    # date = [instance.date]
    # time = [instance.time]
    # fullname = [firstname + lastname]
    # details = [service]
    send_mail(firstname, subject, email,
              ['cmadiam@abc.com'], fail_silently=False)

我错过了什么吗？

再次感谢！

得到这个工作...如果有人需要它...这是代码...

from .models import Booking

@receiver(post_save, sender=Booking)
def new_booking(sender, instance, **kwargs):
if instance.firstname:
    firstname = (instance.firstname)
    email = (instance.email)
    subject = (instance.service)
    send_mail(firstname, subject, email,
              ['cmadiam@abc.com'], fail_silently=False)
