基於 django 自帶的用戶認證進行用戶認證

django admin 默認已經存在了一個用戶認證，這個時候能夠偷個小懶，直接用 django 自帶的，就不須要本身寫用戶認證了css

一、目錄結構：html

二、代碼 python

在 settings.py 中添加一行

# 若是不添加該行，則在未登陸狀態打開頁面的時候驗證是否登陸的裝飾器跳轉到 /accounts/login/ 下面
# 第一種解決方法就是修改 settings.py 中的 LOGIN_URL
# 第二種解決方法是在 url 中匹配該 url
LOGIN_URL = "/login/"

CRM/app01/models.py

from django.db import models
from django.contrib.auth.models import User

class UserProfile(models.Model):
    """帳戶信息表"""
    user = models.OneToOneField(User)   # 跟 django 的 User 表作一個一對一
    name = models.CharField(max_length=32)
    roles = models.ManyToManyField("Role", blank=True, null=True)
