Django实现学生管理系统 Django实现学生管理系统

yaoliuwei1426 人气:0

Django学习笔记-学生管理系统（Django实现）笔记中仅实现了对数据的全部查询。

下面实现新增、删除、修改，代码如下。

下面的代码没有对输入框内容进行限制，如果输入不符合规则的内容，会出现错误。

本篇更新完毕后Django更新暂停一段，由于工作岗位是测试工程师，后面将重点关注测试相关内容。

def add_stuinfo(request):
  if request.method == "POST":
    id = request.POST['id']
    name = request.POST['name']
    math = request.POST['math']
    chinese=request.POST['chinese']
    english=request.POST['english']
    total=float(math)+float(chinese)+float(english)
    models.Stuinfo.objects.create(id=id,name=name,math=math,chinese=chinese,english=english,total=total)
    return HttpResponseRedirect(reverse('stuinfo'))
