Asp.Net MVC 3不具有约束力馆藏车型上发布 [英] Asp.Net MVC 3 not binding collections to models on posting

问题描述

我有许多属性目的其中之一是一些其他复杂对象搜索的阵列
像这样

i have a object with many properties of which one is an array of some other complex object
something like this

class obj1
{
 public string prop1 {get; set;}
 public string prop2 {get; set;}
 public obj2[] array {get; set;}
}
class obj2
{
 SomeEnum Type{get; set;}
 string Content{get; set;}
}

我已经创建了OBJ2阵列编辑模板，可以将其命名为obj2ArrayTemplate结果
这是这样的。

I have created an editor template for the array of obj2 lets name it obj2ArrayTemplate
which is like this

@for (int i = 0; i < Model.Length; i++)
{
    @Html.EditorFor(model=>model[i],"obj2Template")
}

和OBJ2编辑模板，可以将它命名为obj2Template结果
这是这样的。

and an editor template for obj2 lets name It obj2Template
which is like this

<div class="editor-label">
    @Html.DisplayFor(model=>model.Type,"SomeEnum",ViewData)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Content)
    @Html.ValidationMessageFor(model => model.Content)
</div>

现在因为财产键入如果类型 SomeEnum 这是一个枚举，因此不能由Asp.Net MVC结果直接呈现
我创建了一个模板这也结果
这是这样的结果。

now because property Type if of type SomeEnum which is an enum and hence cannot be rendered directly by the Asp.Net MVC
I have created a Template for this too
which is something like this

<input type="text" value="@Model.ToString()" id="@ViewData.TemplateInfo.HtmlFieldPrefix" name="@ViewData.TemplateInfo.HtmlFieldPrefix"/>

视图被正确的渲染并合并渲染视图的HTML是

the view is being rendered correctly and the HTML of the combined rendered view is

<div class="editor-field">
    <input class="text-box single-line" id="array__0__Content" name="array.[0].Content" type="text" value="FBID" />
</div>
<div class="editor-label">
<input type="text" value="Blog" id="array.[1].Type" name="array.[1].Type"/>
</div>
<div class="editor-field">
    <input class="text-box single-line" id="array__1__Content" name="array.[1].Content" type="text" value="SOme random blog" />
</div>
<div class="editor-label">
<input type="text" value="Twitter" id="array.[2].Type" name="array.[2].Type"/>
</div>
<div class="editor-field">
    <input class="text-box single-line" id="array__2__Content" name="array.[2].Content" type="text" value="Twitter Profile" />
</div>

在IAM回发包含表单这个网站结果
铬是我看这个数据发布

when iam posting back the form containing this html
chrome is showing me this posted data

prop1:val1
prop2:val2
array.[0].Type:Facebook
array.[0].Content:FBID
array.[1].Type:Blog
array.[1].Content:SOme random blog
array.[2].Type:Twitter
array.[2].Content:Twitter Profile

但仍阵列领域这是一个的OBJ2阵列类型的模式 OBJ1 是无效

我在做什么错了？

推荐答案

能否破解一个:)结果
检查当时正在从我发现有一个服务器发布的请求。（点）在请求额外所以数组不被填充结果
所以不是

Could crack that one :)
inspecting the request that was being posted from the server I found out that there is one .(dot) extra in the request so the array is not being populated
so instead of

array.[0].Type:Facebook
array.[0].Content:FBID
array.[1].Type:Blog
array.[1].Content:SOme random blog
array.[2].Type:Twitter
array.[2].Content:Twitter Profile

这应该被调回

array[0].Type:Facebook
array[0].Content:FBID
array[1].Type:Blog
array[1].Content:SOme random blog
array[2].Type:Twitter
array[2].Content:Twitter 

我发现为什么Asp.Net MVC框架中额外的点放的没有明显的原因。当IM样做的一切的MVC方式的结果
所以我改变了我的code，包括一个小的黑客。结果
我说这个喜欢OBJ 2的编辑器模板

and I found no apparent reason of why Asp.Net MVC framework is putting in that extra dot. when im kind of doing everything the MVC way
so I changed my code to include a little hack.
I added this like to the Editor template of obj 2

@{
    ViewData.TemplateInfo.HtmlFieldPrefix = ViewData.TemplateInfo.HtmlFieldPrefix.Replace(".", "");
    }

所以现在一切都运行良好，平稳。

so now everything is running fine and smooth.
