利用django在前端页面上完成注册登陆功能
注意：数据库表格要先创建，不管是注册和登录，这个表必须先存在。

# 在终端输入，注意，在项目所在文件夹下。
python3 manage.py makemigrations
python3 manage.py migrate

views.py :

from django.shortcuts import render,HttpResponse,redirect

# Create your views here.

def register(request):
    if request.method == 'POST':
        from app02 import models

        name = request.POST.get('user')
        password = request.POST.get('password')
        re_password = request.POST.get('re_password')
        user = models.User_data.objects.filter(name=name)
        if not user:
            if name and password and password == re_password:
                models.User_data.objects.create(name=name,password=password)
                return HttpResponse('注册成功')
            return HttpResponse('注册失败')
        else:
            return HttpResponse('用户已经注册了！')
    return render(request,'register.html')


def login(request):
    if request.method == 'POST':
        from app02 import models

        name = request.POST.get('user')
        password = request.POST.get('password')
        user = models.User_data.objects.filter(name=name,password=password)
        if user:
            return HttpResponse('登录成功')
        return HttpResponse('登陆失败')
    return render(request,'三层架构.html')

models.py

from django.db import models

# Create your models here.

class User_data(models.Model):
    name = models.CharField(max_length=10,verbose_name='name')
    password = models.CharField(max_length=10,verbose_name='password')
    age = models.IntegerField(verbose_name='age',null=True)
