解决办法：

首先看到这个用户已经保存了

但是没有密码，因为没有设置password

现在设置：

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

https://www.django-rest-framework.org/api-guide/fields/

再试试：

先删除

密码是明文的，需要修改：

设置密文：

password = serializers.CharField(
    style={'input_type': 'password'}
)

效果有了：

密码不能明文返回：

write_only=True

看这里，又是明文：

再次删除记录

    def create(self, validated_data):
        user = super(UserRegSerializer, self).create(validated_data=validated_data)
        user.set_password(validated_data["password"])
        user.save()
        return user

返回对了

密码也加密了

=========================

下面说取代以下代码的更方便的方法：

    def create(self, validated_data):
        user = super(UserRegSerializer, self).create(validated_data=validated_data)
        user.set_password(validated_data["password"])
        user.save()
        return user

https://docs.djangoproject.com/en/1.10/ref/signals/

https://www.django-rest-framework.org/api-guide/authentication/

新建：

C:\Users\huang\PycharmProjects\MxShop\apps\users\signals.py

from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.auth import get_user_model

User = get_user_model()


@receiver(post_save, sender=User)
def create_auth_token(sender, instance=None, created=False, **kwargs):
    if created:
        password = instance.password
        instance.set_password(password)
        instance.save()

from django.apps import AppConfig


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

    def ready(self):
        import users.signals

下面：

makemigrations

migrate

下面看一下有没有效果：

一、后台添加
