如何从不同的模型/控制器渲染局部视图? [英] How to render a partial view from a different model/controller?

问题描述

我在〜/Views/Category/_Categories中有以下名为_Categories的局部视图:

I have the following partial view called _Categories residing in ~/Views/Category/_Categories:

@model IEnumerable<MyBlogSite.Models.BlogPostCategory>

<ul>
@foreach (var item in Model)
{
    <li>@Html.DisplayFor(modelItem => item.Name)</li>
}
</ul>

我在〜/Views/Blog/Index.cshtml中具有以下索引视图:

I have the following Index view at ~/Views/Blog/Index.cshtml:

@model IEnumerable<MyBlogSite.Models.BlogPost>

@{
   ViewBag.Title = "Index";
 }

@Html.RenderPartial("~/Views/Category/_Categories.cshtml", ---- );

<p>
   @Html.ActionLink("New Blog Post", "Create")
</p>
<table>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Title)
    </th>       
    ...

在上面的短划线(----)处，我一直试图弄清楚如何传递模型.我无法使用Model.BlogPostCategory，因为它仅接受Model.BlogPost.根据我在这里看到的几篇文章，我还尝试使用小写的"m"作为模型".

In the space of the dashes (----) above is where I have been trying to figure out how to pass the model in. I cannot use Model.BlogPostCategory because it only accepts Model.BlogPost. I have also tried "model" with a lower-case "m" as per a couple of posts that I saw here.

推荐答案

我为我的 partialview 创建 viewmodel ，然后传递其数据.例如: 我的视图模型

I create viewmodel for my partialview, then pass its data. For example: my viewmodel

public class CompanyCreateViewModel
{
    public Company Company { get; set; }
    public IList<CompanyContact> CompanyContacts { get; set; }
    public IQueryable<ContactType> ContactTypes { get; set; }
}

partialview

@model Invoice.Model.HelperClasses.CompanyCreateViewModel
---
<div class="editor-field">
        @Html.TextBoxFor(model => model.Company.FullName)
        @Html.ValidationMessageFor(model => model.Company.FullName)
        @Html.TextBoxFor(model => model.Company.ShortName)
        @Html.ValidationMessageFor(model => model.Company.ShortName)
        @Html.TextBoxFor(model => model.Company.TIN)
        @Html.ValidationMessageFor(model => model.Company.TIN)
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(model => model.Company.Address.Country)
        @Html.TextBoxFor(model => model.Company.Address.City)
        @Html.TextBoxFor(model => model.Company.Address.Street)
    </div>    
    ---

并调用 partialview

@model Invoice.Model.HelperClasses.CompanyViewModel
---
<div id="CompanyCreateModal" class="modal hide fade">
    @{Html.RenderPartial("CompanyParts/CompanyCreateModal", new Invoice.Model.HelperClasses.CompanyCreateViewModel() { ContactTypes = Model.ContactTypes });
    }
</div>
----
