Django drf使用Django自带的用户系统的注册功能

# 验证电话号码是否有误
import re
from django.core.exceptions import ValidationError
# 对手机格式进行验证
class UnicodMobileValidator:
    def __call__(self, value):
        if not re.match(r"^1[3-9]\d{9}$", value):
             raise ValidationError("对不起,手机格式有误!")
# 对邮箱格式进行验证
class UnicodEmailValidator:
    def __call__(self, value):
        if not re.match(r"^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*\.[a-zA-Z0-9]{2,6}$", value):
             raise ValidationError("对不起,邮箱格式有误!")

from datetime import timezone
from django.contrib.auth.validators import UnicodeUsernameValidator
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, AbstractUser
from qianxingtong_main.utils.validator import UnicodMobileValidator, UnicodEmailValidator
class User(AbstractUser):
    username_validator = UnicodeUsernameValidator()
    username = models.CharField(
        ("username"),
        max_length=150,
        unique=True,
        help_text=(
            "Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only."
        validators=[username_validator],
        error_messages={
            "unique": ("该用户名已经存在"),
    email = models.EmailField(("email address"), unique=True, validators=[UnicodEmailValidator()],error_messages={"unique": ("邮箱已经存在"),})
    mobile = models.CharField(max_length=15, unique=True, validators=[UnicodMobileValidator()],
                              error_messages={"unique": ("电话号码已经存在")}, verbose_name="手机号码")
    class Meta:
        db_table = "drf_user"
        verbose_name = "用户信息"
        verbose_name_plural = verbose_name
这里在迁移数据的时候可能会出现错误,其中错误的解决方法参考我写的笔记:https://www.jb51.net/article/275133.htm 的第三步
3.创建序列化类
user\serializers代码:
from django.contrib.auth.hashers import make_password
from rest_framework import serializers
from user.models import User
class UserSerializer(serializers.ModelSerializer):
    rpassword = serializers.CharField(required=True, write_only=True, help_text="确认密码")
    token = serializers.CharField(max_length=1024, read_only=True, help_text="token认证字符串")
    class Meta:
        model = User
        fields = ["id", "username", "email", "mobile", "password", "token", "rpassword"]
        # write_only:只写入数据库,
        extra_kwargs = {
            "mobile": {
                "write_only": True,
            "email": {
                "write_only": True,
            "id": {
                "read_only": True,
    def validate(self, attrs):
        """校验信息"""
        password = attrs.get("password")
        rpassword = attrs.get("rpassword")
        if password != rpassword:
            # 验证手机号码是否已经被注册
            raise serializers.ValidationError("对不起,确认密码与密码不一致!")
        return attrs
    def create(self, validated_data):
        """保存用户信息"""
        mobile = validated_data.get("mobile")
        username = validated_data.get("username")
        email = validated_data.get("email")
        validated_data.pop("rpassword")  # 移除不需要的数据
        # 对密码进行加密
        raw_password = validated_data.get("password")
        hash_password = make_password(raw_password)
        # 调用序列化器提供的create方法
        user = User.objects.create(
            mobile=mobile,
            username=username,
            password=hash_password,
            email=email
        return user
这个代码就是我与其他的博主不同的地方,我看网上的up主就是把验证的代码写在validate中,但是这里存在的一个问题就是所有的错误都是统一一起打包返回,无法在前端中做对应字段的错误提示.
4.创建views类
user\views代码:
from rest_framework.generics import CreateAPIView
from user.models import User
from user.serializers import UserSerializer
# Create your views here.
class UserViewSets(CreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer
