1、Django auth用户认证

Django auth用户认证自带了一套用户认证模块：
from django.contrib import auth

2、Django auth用户模型

Django auth用户认证，必然少不了该模块的模型(models)：
该模块的模型(models) :
1.AbstractBaseUser --> 他是一个基类

class AbstractBaseUser(models.Model):password = models.CharField(_("password"), max_length=128)last_login = models.DateTimeField(_("last login"), blank=True, null=True)is_active = TrueREQUIRED_FIELDS = []_password = Noneclass Meta:abstract = True

2.AbstractUser --> 继承AbstractBaseUser 也是一个抽象类

class AbstractUser(AbstractBaseUser, PermissionsMixin):username_validator = UnicodeUsernameValidator()username = models.CharField(_("username"),max_length=150,....)first_name = models.CharField(_("first name"), max_length=150, blank=True)last_name = models.CharField(_("last name"), max_length=150, blank=True)email = models.EmailField(_("email address"), blank=True)is_staff = models.BooleanField(_("staff status"),default=False,.....)is_active = models.BooleanField(_("active"),default=True,....)date_joined = models.DateTimeField(_("date joined"), default=timezone.now)objects = UserManager()EMAIL_FIELD = "email"USERNAME_FIELD = "username"REQUIRED_FIELDS = ["email"]class Meta:verbose_name = _("user")verbose_name_plural = _("users")abstract = True

3.User–> 继承AbstractUser

class User(AbstractUser):class Meta(AbstractUser.Meta):swappable = "AUTH_USER_MODEL"

3、自定义auth用户模型

我们只要重定义User就可以了，但是必须继承AbstractUser 类
并且在配置文件中需要定义：AUTH_USER_MODEL = "users.UserDetail"
users：是app应用名
UserDetail：是定义的类名

# users应用中models.py重定义auth用户模型
from django.db import models
from django.contrib.auth.models import AbstractUser
class UserDetail(AbstractUser):age = models.DateField(null=True)desc = models.TextField(null=True)sex = models.CharField(max_length=4)school_status = models.CharField(max_length=4)grade = models.CharField(max_length=16)

4、数据迁移

自定义好模型，就是数据迁移
python manage.py makemigratation
python manage.py migrate

5、web开发一个应用

5.1 定义路由

1.一级路由

from django.contrib import admin
from django.urls import path
from django.urls import re_path
from django.urls import includeurlpatterns = [path('admin/', admin.site.urls),re_path('^user/', include("users.urls")),re_path('^user/', include("users.urls")),# re_path(r'^user/',include(('users.urls',"users"),namespace="user")) # 通过{% url 'user' %}访问
]

2.二级路由

from django.urls import re_path
from . import views
urlpatterns = [re_path('login/$', views.login, name='login'),re_path('register/$', views.register, name='register'),
]

5.2 定义视图函数

from django.shortcuts import render
from django.http import HttpResponseForbidden, JsonResponse
from django.contrib.auth import authenticate
from users.models import UserDetail
from utils.serializer import UserDetailSerializerdef login(request):if request.method == 'GET':return render(request, 'login.html')else:username = request.POST.get('username')password = request.POST.get('password')request_user = authenticate(request, username=username, password=password)if request_user is not None:return render(request, 'index.html', {'request_user': request_user})else:return render(request, 'login.html')def register(request):if request.method == 'GET':return render(request, 'register.html')else:data = {'username': request.POST.get('username'),'password': request.POST.get('password'),'age': request.POST.get('age'),'desc': request.POST.get('desc'),'sex': request.POST.get('sex'),'school_status': request.POST.get('school_status'),'grade': request.POST.get('grade'),}serializer = UserDetailSerializer(data=data)if serializer.is_valid():# 如果要使用authenticate()函数认证用户，必须要对password进行哈希加密处理，而create_user()创建用户，就对密码进行了哈希，最好使用create_user创建用户request_user = UserDetail.objects.create_user(**serializer.data)return render(request, 'index.html', {'request_user': request_user})else:return HttpResponseForbidden("注册失败")

5.3 定义模板

1、模板调用关系：login继承base，并包含form
2、模板调用关系：register继承base，并包含form

<!-- base.html -->
<!DOCTYPE html>
