1、settings.py

激活应用

INSTALLED_APPS = ['django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','myapp'#激活应用
]

连接数据库，这里是SQL server

##连接数据库
DATABASES = {'default': {'ENGINE': 'sql_server.pyodbc','NAME': 'bishe','USER':'sa','PASSWORD':'root','HOST':'localhost','PORT':'','OPTIONS': {'driver':'SQL Server Native Client 11.0','MARS_Connection': True,}}
}

注释掉这句话


记得改位置

2.在myapp文件夹下创建文件夹Templates

用来存html文件， index.html, login.html,register.html，三个文件后边展示代码

在项目的urls.py文件中加入两句话

from django.contrib import admin
from django.urls import path
from django.urls import path, include  #1urlpatterns = [path('admin/', admin.site.urls),path('myapp/', include('myapp.urls')) #2
]

在myapp文件夹里新建urls.py文件
输入代码：

from django.urls import path
from . import views
urlpatterns = [path('registe/', views.register,name='register'),path('log/', views.login,name='login'),
]

在myapp里的models.py文件中输入类：

from django.db import models# Create your models here.class User(models.Model):name = models.CharField(max_length=50)password = models.CharField(max_length=50)telephone = models.CharField(max_length=50,primary_key=True)email = models.CharField(max_length=50)#定义默认输出格式def __str__(self):return "%s,%s,%s,%s"%(self.name,self.password,self.telephone,self.email)#自定义对应的表名class Meta:db_table="user"

在Myapp里的views.py中输入代码

from django.shortcuts import redirect, render
from django.http import HttpResponse
from myapp.models import User
from django.contrib.auth import authenticate,login,logout
from django.contrib.auth.backends import ModelBackend# Create your views here.
def index(request):login_msg="恭喜！登录成功"return render(request,'index.html',{'login_msg':login_msg})def register(request):if request.method=='POST':userName=request.POST.get('userName')userTelephone=request.POST.get('userTel')userEmail=request.POST.get('userEmail')userPassword=request.POST.get('userPassword')userRePassword=request.POST.get('userRePassword')try:user=User.objects.get(telephone=userTelephone)if user:msg="用户已存在"return render(request,'register.html',{'msg':msg})except:if userPassword!=userRePassword:error_msg="密码不一致"return render(request,'register.html',{'error_msg':error_msg})else:register=User()register.name=userNameregister.telephone=userTelephoneregister.password=userPasswordregister.emaild=userEmailregister.save()return redirect('/myapp/log/')else:return render(request,'register.html')def login(request):if request.method=='POST':userTelephone=request.POST.get('usertel')userPassword=request.POST.get('userpassword')if User.objects.get(telephone=userTelephone):if User.objects.get(telephone=userTelephone).password==userPassword:msg='恭喜登录成功！'return render(request,'index.html',{'login_msg':msg})else:msg='手机号或密码错误'return render(request,'login.html',locals(),{'msg':msg})else:msg='用户不存在，请先注册！'return render(request,'login.html',locals(),{'msg':msg})else:return render(request,'login.html')

3.html页面

1.login.html

2.register.html

4.测试

win+r ,cmd ,进到manage.py路径中

输入python manage.py runserver

C:\Users\86182\OneDrive\桌面\毕业设计\vscode\Liyanlin_BiShe>python manage.py runserver
