远程验证不会将数据传递给操作

Question

我有模特:

public class MyModel
...fields
[Remote(ActionName, ControllerName)]
public string SomeNumber { get; set; }
..fields

并在ControllerName控制器中执行操作:

public JsonResult ActionName(string someNumber)
{...}

但是当调用action时,参数someNumber总是为null.当我尝试调试它时,我得到了

GET /ControllerName/ActionName?MyModel.SomeNumber =34189736 

我怎样才能使它工作？(我无法传递整个模型MyModel,并且无法在我的视图中更改MyModel.SomeNumber字段的名称)

UPD.在我看来输入:

<input data-val="true" data-val-remote-additionalfields="*.SomeNumber" data-val-remote-url="/ControllerName/ActionName" id="MyModel_SomeNumber" name="MyModel.SomeNumber" type="text" value="34189734" class="valid">

UPD解决了!:)我用单个字段SomeNumber创建新模型并使用前缀:

SomeNumber([Bind(Prefix = "MyModel")]MySingleFieldModel model)

如果您使用嵌套ViewModels,则需要接受父ViewModel作为操作中的参数Validation.例如:

public class ParentViewModel
{
    public UserViewModel User {get; set; }

    //....
}

public class UserViewModel 
{
    [Remote("UniqueUsername", "Validation")]
    public string Username { get; set; }

    //....
}

在ValidationController中:

public class ValidationController : Controller
{ 
     public JsonResult UniqueUsername(ParentViewModel Registration) 
     {
        var Username = Registration.User.Username; //access the child view model property like so

        //Validate and return JsonResult

     }
}
