必填字段验证程序在azure上的Django中不起作用

我有一个简单的注册表单。人们可以填写信息并提交表格时，数据应该存入数据库。必填字段验证程序在azure上的Django中不起作用

该应用程序在我的本地主机上正常工作。我的表单中有一些必填字段。当我在本地主机上运行应用程序时，我尝试提交没有填写必填字段的表单，然后显示一个弹出窗口，并说**该字段不能为空**，但是当我将其部署到我的天蓝色门户时，试图挽救这个没有填写必填字段，然后它会产生错误：

您还没有在任何地方拨打is_valid。它应该是：

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

我做到了前面，但随后抛出错误：局部变量“变量”引用之前线返回分配渲染（要求，“注册/ register.html”，变量） –

您需要将'variables'的定义移回一个缩进。 –

好的，它的工作很好谢谢，但如何要求字段将工作，这是我在这篇文章中的实际问题 –
