Question

我有一个简单的注册表格。如果人们可以填写信息，当他们提交表格时，数据应该放在数据库中。

应用程序在我的localhost中正常运行。我的表格中有一些必填字段。当我在我的localhost上运行应用程序并尝试提交表单而不填写必填字段时，它会显示一个弹出窗口并说明**该字段不能为空**，但当我将其部署在我的天蓝色门户网站上时尝试保存此而不填写必填字段然后它会生成错误：

Answer 1

您尚未在任何地方拨打is_valid。它应该是：

 if request.method == 'POST':
     form = UserInformationForm(request.POST)
     if form.is_valid():
         form.save()
         return HttpResponseRedirect('/register/success/')

必需的字段验证器在azure上的Django中不起作用
