Posted 2020-12-21 wandn

1.models.py

class Users(models.Model):
    password = models.CharField(max_length=100,verbose_name=‘用户名‘)
    account = models.CharField(max_length=100,verbose_name=‘密码‘)

    def __str__(self):
        return self.account

 

 

 

2.views.py

 

from django.shortcuts import render,HttpResponse
from management.models import Book,Image,Users

def sign_up(request):
    elif request.method == ‘POST‘:
        dengluaccount = request.POST.get(‘denglumima‘,default=‘‘)
        denglupassword = request.POST.get(‘dengluzhanghao‘,default=‘‘)
        print("登录账号:" + denglupassword + "登录密码:" + dengluaccount)
        if dengluaccount != ‘‘:
            if denglupassword != ‘‘:
                #password与account写反了
               try:
                   zh = Users.objects.filter(password=denglupassword)  # 获取密码账号为deluaaccount的密码
                   print(zh[0])
                   if str(zh[0]) == str(dengluaccount):
                       print("登录成功")
               except:
                   print("登陆失败")

            else:
                print("密码不能为空")
        else:
            print("账号不能为空")
    return HttpResponse(render(request, ‘login.html‘,{"Book_name":book_name}))
