你可以使用嵌套的视图模型在ASP.net MVC3？ [英] Can you use nested view models in ASP.net MVC3?

问题描述

下面是我在做什么的简化版本。

Here is a simplified version of what I am doing.

我已经创建了一个包含数据的企业视图模型。公司拥有3个地址。所以，巧言令色我创建了一个AddressViewModel和_address部分。

I have created a view model that contains data for a Company. The company has 3 addresses. So trying to be clever I created an AddressViewModel and an _address partial.

我的问题是，虽然我可以通过AddressViewModel的部分，它使该地址现在我有重复的ID在HTML ...所以现在有三个1号线表单上输入字段这当然不张贴回正常。

The problem I have is that while I can pass the AddressViewModel to the partial and it renders the address I now have duplicate id's in the HTML... so there are now three "Line1" input fields on the form which of course don't post back properly.

我怎样才能解决这个问题。就是真正扁平化视图模型，并具有唯一的办法，

How can I resolve this issue. Is the only way to really flatten the ViewModel and have,

MainAddressLine1
MailAddressLine1
BillAddressLine1

MainAddressLine1 MailAddressLine1 BillAddressLine1

在公司视图模型？而且，如果我这样做，我还可以用_address部分以某种方式？

in the company view model? And, if I do this, can I still use the _address partial in some way?

推荐答案

使用编辑模板，而不是部分：

Use an editor template instead of a partial:

@model MainViewModel
@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.MainAddress)
    @Html.EditorFor(x => x.MailAddress)
    @Html.EditorFor(x => x.BillAddress)

    <button type="submit">OK</button>
}

，然后在〜/查看/共享/ EditorTemplates / AddressViewModel.cshtml ：

@model AddressViewModel
@Html.EditorFor(x => x.Street)
@Html.EditorFor(x => x.ZipCode)
...

现在你不必担心输入字段的名称和ID。他们将正确处理。

Now you don't have to worry about the names and ids of the input fields. They will be correctly handled.
