django数据入库
1、声明类
1、声明类: e = Employee() e.name = '入库数据' e.save()即可存入
2、直接类中使用:
ee = Employee(name='aa') ee.save()
3、自带返回值:
Employee.objects.create(name='字段值') Django是在views.py文件中,通过导入models.py文件来创建数据的: from django.shortcuts import render # Create your views here. from blog import models #导入blog模块 from django.shortcuts import HttpResponse def db_handle(request): models.UserInfo.objects.create(username='andy',password='123456',age=33) return HttpResponse('OK') 上面就是创建表数据,也可以通过字典的格式来创建表数据: def db_handle(request): # models.UserInfo.objects.create(username='andy',password='123456',age=33) dic = {"username":"bruce","password":"123456","age":23} models.UserInfo.objects.create(**dic) return HttpResponse('OK')
查询:
result = Employee.objects.all() 返回数据对象 直接在页面中输出: from blog.models import Employee from django.shortcuts import render_to_response def index(req): a= Employee.objects.all() return render_to_response('index.html',{'items':a}) 页面视图: {% for i in items%} <div>{{i}}</div> {% endfor %}
