我通过接口创建用户之后，数据库中的密码还是明文的，用户也登录不上，是信号量没有起作用吗，为什么呢？

settings  INSTALLED_APPS = ['user']

修改成

settings  INSTALLED_APPS = ['user.apps.UserConfig']

这样才会加载 def ready(self): 函数   信号量才会生效

AppConfig中没有加载singal?

• 提问者 fbb123456 #1

  加了啊，你是说这里吧：
  class UsersConfig(AppConfig):
      name = 'users'
      verbose_name = "用户管理"
  
      def ready(self):
          import users.signals

  你贴一下你的signal代码以及你的view里面的添加用户的代码逻辑

• 提问者 fbb123456 回复 bobby #3

  signal:
  from django.db.models.signals import post_save
  from django.dispatch import receiver
  from rest_framework.authtoken.models import Token
  from django.contrib.auth import get_user_model
  
  User = get_user_model()
  
  @receiver(post_save, sender=User)
  def create_user(sender, instance=None, created=False, **kwargs):
      if created:
          password = instance.password
          instance.set_password(password)
          instance.save()
