如何获得模型验证，以在MVC3列表设置对象的属性皮卡？ [英] How to get model validation to pickup attributes set on objects in a List in MVC3?

问题描述

我有一组模型，类似于此

I have a set of models that looks similar to this

public class OtherModel 
{
    [Required]
    string name { get; set; }
}

public class OthersEditModel 
{
    List<OtherModel> others { get; set; }
}

然后我有一个看起来像这样的控制器方法

I then have a controller method that looks like this

[HttpPost]
public ActionResult EditOthers(OthersEditModel others)
{
    if(ModelState.IsValid)
    {
         // Save
    }
}

我的问题是，在列表中的对象的 ModelState.IsValid 不触发验证。

我如何做到这一点，或者是它甚至可能吗？

How do I accomplish this, or is it even possible?

或者替换地可以我手动触发的元素列表中的验证？

Or alternatively can I manually trigger the validation of the elements in the list?

推荐答案

因此​​，原来的问题不在于验证属性。他们拿起完美的，没有做任何事情的基础 OthersEditModel 。我打破了动态JavaScript形式产生，使表单字段，用不正确的名称回来了。

So it turns out that the problem wasn't the validation properties. They pick up perfectly, without doing anything to the base OthersEditModel. I had broken the dynamic JavaScript form generation, so the form fields were coming back with incorrect names.
