from django.contrib import admin
from django.urls import path,include
from app01 import views
urlpatterns = [
path('credata/', views.credata),
]

from django.shortcuts import HttpResponse
import pymysql
pymysql.install_as_MySQLdb()
from app01 import models
def credata(request):
#创建插入数据
# models.UserInfo.objects.create(
#     username='song',
#     password='123',
#     age='18'
# )

#查询数据
# a =models.UserInfo.objects.filter(username='root')
# for i in a:
#     print(i.id,i.username,i.password,i.age)

#查到数据后进行删除
# models.UserInfo.objects.filter(username='root').delete()

#更新数据,找到所有的列，把密码改成123456
models.UserInfo.objects.all().update(password='123456')

return HttpResponse('OK')
