更改用户密码后在 Django 模型中发送邮件的最佳方式?
Best way to send a mail in Django Model when a user's password has been changed?
我是 python 和 django 今年的新手,我只是在努力弄清楚如何在更新密码后通过 send_mail
向用户发送一封简单的邮件?
我已经通过 pre_save
的 Signals 对此进行了管理,但是我不想让用户等到邮件已发送(据我所知我无法解决)。使用post_save
,无法查询到之前的状态。
如果我给出以下用户模型,这里最好的方法是什么?
class User(AbstractBaseUser):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
email = models.EmailField(verbose_name="email address", max_length=255, unique=True)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
USERNAME_FIELD = "email"
REQUIRED_FIELDS = []
# Tells Django that the UserManager class defined above should manage
# objects of this type
objects = UserManager()
def __str__(self):
return self.email
class Meta:
db_table = "login"
我用 pre_save 信号设置了它,但由于延迟,这对我来说不是解决方案:
@receiver(pre_save, sender=User)
def on_change(sender, instance: User, **kwargs):
if instance.id is None:
pass
else:
previous = User.objects.get(id=instance.id)
if previous.password != instance.password:
send_mail(
"Your password has changed",
"......",
"info@examplpe.com",
[previous.email],
fail_silently=False,
)
提前致谢
如果您使用的是自定义模型,您可能可以通过对 set_password()
的调用来在实例上设置标志,然后检测其在信号中的存在。
试试这个例子:
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin
from django.db.models.signals import post_save
class User(AbstractBaseUser, PermissionsMixin):
...
def set_password(self, password):
super(User, self).set_password(password)
self._set_password = True
@classmethod
def user_changed(cls, sender, instance, **kwargs):
if getattr(instance, '_set_password', False):
# Send your mail
post_save.connect(User.user_changed, sender=User)
您可以覆盖用户模型的保存方法。这是来自 docs alongside a check for changed values from SO:
的示例
class User(AbstractBaseUser):
...
__original_password = None
def __init__(self, *args, **kwargs):
super(User, self).__init__(*args, **kwargs)
self.__password = self.password
def save(self, *args, **kwargs):
if self.password != self.__original_password:
notify_user_of_password_change()
super().save(*args, **kwargs) # Call the "real" save() method.
