7.models

这次的模型继承AbstractUser类，里面自带了一些属性，再新建下边的属性：

from django.db import models
from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.


class UserProfile(AbstractUser):
    nickname = models.CharField(max_length=50,verbose_name="昵称",default='')
    birday = models.DateField(verbose_name = "生日",null=True,blank=True)
    gender = models.CharField(choices=(("male","男"), ("female","女")), max_length=5, default="female")
    address = models.CharField(max_length=100,default="")
    mobile = models.CharField(max_length=11,null=True,blank=True)
    image = models.ImageField(upload_to="image/%Y/%m",default="image/default.png")

    class Meta:
        verbose_name = "用户信息"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

其中ImageField功能需要pillow包，安装到虚拟环境里。settings里把users放到installed_apps里，再加上个

AUTH_USER_MODEL = "users.UserProfile"

其中users为app名，UserProfile为模型类名
然后数据迁移makemigration和migrate。

本项目需要3个主要应用，包括users、organisations、courses。要避免这三个应用循环引用，可以再创建一个应用叫operations，用于处理这三个应用的交互。另外有些功能用的比较少，随便找个地方放就行，我们就决定放在users里了。包括验证邮箱发验证码和轮播图。都放在users的models.py里了。

from django.db import models
from datetime import datetime
from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.


class UserProfile(AbstractUser):
    nickname = models.CharField(max_length=50,verbose_name="昵称",default='')
    birday = models.DateField(verbose_name = "生日",null=True,blank=True)
    gender = models.CharField(choices=(("male","男"), ("female","女")), max_length=5, default="female")
    address = models.CharField(max_length=100,default="")
    mobile = models.CharField(max_length=11,null=True,blank=True)
    image = models.ImageField(upload_to="image/%Y/%m",default="image/default.png")

    class Meta:
        verbose_name = "用户信息"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

class EmailVerifyRecord(models.Model):
    code = models.CharField(max_length=20, verbose_name="验证码")
    email = models.EmailField(max_length=50,verbose_name="邮箱")
    send_type = models.CharField(choices=(("register","注册"),("forget","忘记密码")),max_length=10)
    send_time =  models.DateTimeField(default=datetime.now)

    class Meta:
        verbose_name = "邮箱验证码"
        verbose_name_plural = verbose_name

class Banner(models.Model):
    title = models.CharField(max_length=100, verbose_name="标题")
    image= models.ImageField(upload_to="banner/%Y/%m", verbose_name="轮播图",max_length=100)
    url = models.URLField(max_length=200,verbose_name="访问地址")
    index = models.IntegerField(default=100, verbose_name="顺序")
    add_time = models.DateTimeField(default=datetime.now,verbose_name="添加时间")

    class Meta:
        verbose_name = "轮播图"
        verbose_name_plural = verbose_name

其中验证码类里的send_time用于记录发验证码的时间，已设置超时过期。default=datetime.now中如果写now()则会返回创建项目的时间。datetime功能需要import。轮播图的url用于记录每个图片的超链接地址，index用于记录轮播图的序号（顺序）。
