如果我有导航属性怎么办?我试图编辑的模型中有另一个模型的集合。我想显示集合属性中每个对象的复选框列表。到目前为止,这就是我尝试的。。。
@{
foreach (var category in ViewBag.Categories)
{
if (Model.Categories.Contains(category))
{
<input type="checkbox" name="selected-categories" value="category.CategoryId" checked="checked" />@category.Name
}
else
{
<input type="checkbox" name="selected-categories" value="@category.CategoryId" />@category.Name
}
}
}
但它以EntityCommandExecutionException失败。在if语句中,如何访问模型。像我这样的类别在@Html.EditorFor(model => model.Id)
???
我会使用强类型视图。创建一个包含您的模型的ViewModel,并将此ViewModel用于强类型视图。
域模型和视图模型(简化)
public class YourModel
{
string Category { get ; set ; }
}
public class YourViewModel
{
public List<string> PossibleCategories { get ; set ; }
public YourModel YourData { get ; set ; }
}
然后视图:
@model YourViewModel
@{
foreach (string CurrCategory in Model.PossibleCategories)
{
if (Model.YourData.Category == CurrCategory)
{
@Html.CheckBox(CurrCategory, new { @checked = "checked" })
@Html.Encode(CurrCategory) <br />
}
else
{
@Html.CheckBox(CurrCategory, false)
@Html.Encode(CurrCategory) <br />
}
}
}
