django-allauth：如何正确使用email_confirmed信号将用户设置为活动状态

在另一篇文章中，我提到我试图使用allauth的email_confirmed信号将已确认用户的is_active字段更改为true。但是，以下代码给了我一个例外：“用户匹配查询不存在”。

from allauth.account.signals import email_confirmed
from django.dispatch import receiver
from django.contrib.auth.models import User

@receiver(email_confirmed)
def email_confirmed_(request, email_address, **kwargs):

    user = User.objects.get(email=email_address)
    user.is_active = True

    user.save()

我尝试对此进行重新处理，但仍然遇到类似的异常，“不存在匹配查询的电子邮件地址”。

from allauth.account.signals import email_confirmed
from django.dispatch import receiver
from django.contrib.auth.models import User
from allauth.account.models import EmailAddress

@receiver(email_confirmed)
def email_confirmed_(request, email_address, **kwargs):

    new_email_address = EmailAddress.objects.get(email=email_address)
    user = User.objects.get(new_email_address.user)
    user.is_active = True

    user.save()

这让我感到困惑，因为我可以同时检查用户表和数据库中“电子邮件地址”表中的电子邮件地址字段，而且它们似乎都具有匹配的电子邮件地址。帮助将不胜感激！
