這次的模型繼承AbstractUser類，里面自帶了一些屬性，再新建下邊的屬性：

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="昵稱",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 = "用戶信息"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

其中ImageField功能需要pillow包，安裝到虛擬環境里。settings里把users放到installed_apps里，再加上個

AUTH_USER_MODEL = "users.UserProfile"

其中users為app名，UserProfile為模型類名
然后數據遷移makemigration和migrate。

本項目需要3個主要應用，包括users、organisations、courses。要避免這三個應用循環引用，可以再創建一個應用叫operations，用于處理這三個應用的交互。另外有些功能用的比較少，隨便找個地方放就行，我們就決定放在users里了。包括驗證郵箱發驗證碼和輪播圖。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="昵稱",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 = "用戶信息"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

class EmailVerifyRecord(models.Model):
    code = models.CharField(max_length=20, verbose_name="驗證碼")
    email = models.EmailField(max_length=50,verbose_name="郵箱")
    send_type = models.CharField(choices=(("register","注冊"),("forget","忘記密碼")),max_length=10)
    send_time =  models.DateTimeField(default=datetime.now)

    class Meta:
        verbose_name = "郵箱驗證碼"
        verbose_name_plural = verbose_name

class Banner(models.Model):
    title = models.CharField(max_length=100, verbose_name="標題")
    image= models.ImageField(upload_to="banner/%Y/%m", verbose_name="輪播圖",max_length=100)
    url = models.URLField(max_length=200,verbose_name="訪問地址")
    index = models.IntegerField(default=100, verbose_name="順序")
    add_time = models.DateTimeField(default=datetime.now,verbose_name="添加時間")

    class Meta:
        verbose_name = "輪播圖"
        verbose_name_plural = verbose_name

其中驗證碼類里的send_time用于記錄發驗證碼的時間，已設置超時過期。default=datetime.now中如果寫now()則會返回創建項目的時間。datetime功能需要import。輪播圖的url用于記錄每個圖片的超鏈接地址，index用于記錄輪播圖的序號（順序）。
