Django数据库基本增删改查操作

urls.py文件里的内容---实现url路由

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

views.py文件里方法定义

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')
