问题描述
我想用两次@Model从我的网站的另一部分是有可能得到的数据?因为现在我有错误,但如果我只有这第一@model一切工作的正确。
外观 - > MVC 3 - 异常详细信息:System.InvalidOperationException
@model IEnumerable<SportsStore.Entities.Towar>
@model IEnumerable<SportsStore.Entities.Kategorie>
@{
ViewBag.Title = "List";
}
<h2>List</h2>
@foreach (var p in Model)
{
<div class="item">
<h3>@p.Nazwa</h3>
@p.Opis
<h4>@p.Cena.ToString("c")</h4>
</div>
}
解决方案
You only can have one Model per View. But you can use another object to declarate the model:
public class SomeViewModel
{
public IEnumerable<Towar> Towars;
public IEnumerable<Category> Categories;
public SomeViewModel(IEnumerable<Towar> towars, IEnumerable<Category> categories) {
Towars = towars;
Categories = categories;
}
}
And then use it in your view like this:
@model SportsStore.Entities.SomeViewModel
@foreach (var item in Model.Towars)
{
<div class="item">
<h3>@p.Nazwa</h3>
@p.Opis
<h4>@p.Cena.ToString("c")</h4>
</div>
}
@foreach (var item in Model.Categories) {
@item.Name @* or what you need down here *@
}
I would also recommend you to use english names in MVC. It's more clear to read and understand ;).
