Django信号量实现用户密码修改

一、完善用户注册

添加一条用户短信验证码数据之后进行验证。

user/views.py

class UserViewset(CreateModelMixin,viewsets.GenericViewSet):
    '''
    用户
    '''
    serializer_class = UserRegSerializer
    queryset = User.objects.all()

user/serializer.py添加

fields = ('username','code','mobile','password')

(2)password不能明文显示和加密保存

需要重载Create方法

#输入密码的时候不显示明文
    password = serializers.CharField(
        style={'input_type': 'password'},label=True,write_only=True
    )

    #密码加密保存
    def create(self, validated_data):
        user = super(UserRegSerializer, self).create(validated_data=validated_data)
        user.set_password(validated_data["password"])
        user.save()
        return user

这是重载Create方法,下面介绍如何用信号量来实现

信号量

(1)users下面创建signals.py

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()


# post_save:接收信号的方式
#sender: 接收信号的model
@receiver(post_save, sender=User)
def create_user(sender, instance=None, created=False, **kwargs):
    # 是否新建,因为update的时候也会进行post_save
    if created:
        password = instance.password
        #instance相当于user
        instance.set_password(password)
        instance.save()

(2)还需要重载配置

users/apps.py

from django.apps import AppConfig

class UsersConfig(AppConfig):
    name = 'users'
    verbose_name = "用户管理"

    def ready(self):
        import users.signals

AppConfig自定义的函数,会在django启动时被运行

现在添加用户的时候,密码就会自动加密存储了
