一、需要知道的知识
#把urls改好 #把settings改好 #创建sqlite库 需要执行两条命令 -python3 manage.py makemigrations # 这条命令会在migrations创建一条记录，数据库变更记录 -python3 manage.py migrate # 把更改同步到数据库 #把sqlite库连接navicat数据库 -打开navicat直接把库拉进去即可 -或者按照 navicat要求创建库，因为orm是不能创建数据库的 #把 register userlist里的样式写好 # # #步骤：
#登录功能（数据要保存到数据库）
（1）配路由 （2）写视图 （3）写模板文件
（4）建一个文件夹static,导入样式
（5）在配置文件中配置样式路径
(6)继续写模板文件
（7）补视图函数，往数据库里插入数据，并通过orm把数据保存到数据库

二、详解
1. models.py
from django.db import models # Create your models here. # 一定要继承models.Model class userinfo(models.Model): # 字段属性--》后面那个对象决定的, # 改字段自增，并且是主键 id = models.AutoField(primary_key=True) # 改字段是varchar类型，长度为32(唯一约束，是否是索引，默认值是，是否可以为空) name = models.CharField(max_length=32) # 密码字段 password =models.CharField(max_length=64,null=True) # 数字类型 gender=models.IntegerField(default=0) # 省份 province=models.CharField(max_length=32,null=True)
2.views.py
from django.shortcuts import render,redirect from app01 import models # Create your views here. def register(request): if request.method=="GET": return render(request,"register.html") elif request.method=="POST": #注册，往数据库里插入数据 res=request.POST print(res) name=res.get("name") password=res.get("password") gender=res.get("gender") province=res.get("province") # 方式一： # 通过orm存到数据库里 # models.userinfo(name=name,password=password,gender=gender,province=province) # print(user.name) # # 保存到数据库 # user.save() # 方式二： user = models.userinfo.objects.create(name=name, password=password, gender=gender, province=province) print(user.name) #直接跳转到用户列表页面 return redirect("/userlist/") def user_list(request): # 通过orm查询所有用户 userlist=models.userinfo.objects.all() # 列表，内部有一个一个的user对象 [user1,user2,user3] print(len(userlist)) # return render(request, 'userlist.html',context={'userlist':所有的用户对象放到列表中}) return render(request, 'userlist.html',context={'userlist':userlist})
