一、设计models

1.1 用户表设计：users/models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
from datetime import datetime


# Create your models here.

class UserProfile(AbstractUser):
    """
    用户表，新增字段如下
    """
    GENDER_CHOICE = (
        ('male', '男'),

    # 用户注册时，我们要新建User_Profile 但是我们只有手机号
    name = models.CharField(max_length=30, null=True, blank=True, verbose_name='姓名')
    # 保存出生日期，年龄通过出生日期推算

    class Meta:

        verbose_name_plural = verbose_name

    def __str__(self):

三、表模型设计说明

1、创建用户

~/Desktop/pythonsyscode/Higoleme/Higolemebackend(master*) » python manage.py createsuperuser  
Username: admin
邮箱: code4fs@gmail.com
Password: 
Password (again): 
Superuser created successfully.
