为什么使用我的路由数据我textBoxFor？ [英] Why is my textBoxFor using my route data?

问题描述

所以，我有以下三行：

<div style="background-color: lightgreen;">@Html.TextBoxFor(m => m.Id)</div>
<div style="background-color: green;">@Html.DisplayTextFor(m => m.Id)</div>
<div style="background-color: pink;">@Model.Id</div>

我已经确定了的浅绿值不是我Model.Id而是由我的路线设置ID：

I've identified that the lightgreen value is not my Model.Id but the Id that is set by my route:

routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "MyFunController", action = "Index", id = UrlParameter.Optional });

我来这里翻过一些说明：

I've come accross some explanations here:

但他们都离开了我对我的胃口。我在寻找一个聪明的办法来解决这个问题，我不想改变我的模型的属性名称也不想改变路线项目的名称。如果我这样做会重新present了很多工作，对我来说，是不理想的。

But they have all left me on my appetite. I'm looking for a smart way to work around this, I don't want to change my model's property names nor do I want to change the name of the route item. If I do it will represent a lot of work for me and is not ideal.

我敢肯定我不是唯一一个有这个问题？

I'm sure I'm not the only one with this issue?

（这是MVC 4）

谢谢！

推荐答案

您可以删除有问题的值的ModelState （这是在HTML佣工使其从）在控制器的动作正在呈现的观点：

You could remove the problematic value from the ModelState (which is where the Html helpers are taking it from) in the controller action that is rendering the view:

public ActionResult SomeAction(int id)
{
    ModelState.Remove("Id");
    MyViewModel model = ...
    return View(model);
}

现在它是要去习惯的文本框，并从路线不是有人来您的视图模型的编号属性。

Now it's the Id property of your view model that's gonna get used by the TextBox and not the one coming from the route.

显然，这只是一个丑陋可怕的解决方法。正确的方法是当然正确定义您的视图模型，这样你就没有这样的命名冲突。

Obviously that's only an ugly horrible workaround. The correct way is to of course properly define your view models so that you do not have such naming collisions.
