from django.db import models

# Create your models here.
class UserInfo(models.Model):
    #CharField是一个字段，相当于字符串
    username=models.CharField(max_length=64)
    sex=models.CharField(max_length=64)
    email=models.CharField(max_length=64)

python manage.py migrate
===============================================

def userInfo(req):
    # req.POST={‘username‘,star,‘sex‘:mail,‘email‘:123@.com}
    if req.method==‘POST‘:
        u=req.POST.get(‘username‘,None)
        s=req.POST.get(‘sex‘,None)
        e=req.POST.get(‘email‘,None)
        # user={‘username‘:u,‘sex‘:s,‘email‘:e}
        # user_list.append(user)
        #将数据存入到数据库
        models.UserInfo.objects.create(
            username=u,
            sex=s,
            email=e,
        )
    #将数据从数据库中取出来呈现到页面上
    user_list=models.UserInfo.objects.all()



    return render(req, ‘index.html‘,{‘user_list‘:user_list})
