Razor生成错误的RenderPartial
Razor生成错误的RenderPartial
提问于 2018-05-31 17:09:49
我有一个页面项目编辑与图像删除的多个部分呈现的形式。项目编辑页面：
@model EditModel
<form method="post" enctype="multipart/form-data">
<input asp-for="ItemModel.Id" type="hidden" />
<input asp-for="ItemModel.AllOtherFields" type="hidden" />
</form>
@if (Model.ItemModel.ImageViewModels != null && Model.ItemModel.ImageViewModels.Any())
{
foreach(var imageViewModel in Model.ItemModel.ImageViewModels)
{
Html.RenderPartial("ItemImage/_itemImageEdit", imageViewModel);
}
}ItemImage/_itemImageEdit
@model ViewModels.ItemImageViewModel
<form asp-controller="Images" asp-action="Delete" method="post">
<input type="hidden" asp-for="@Model.Id" />
<img src="@Url.Action("Get", "Images", new { id = Model.Id })" />
<input type="submit" value="Delete" />
</form>这是我奇怪的最后一个html
<form method="post" action="/Images/Delete/5" novalidate="novalidate">
<input type="hidden" data-val="true" data-val-required="The Id field is required." id="Id" name="Id" value="5">
<img src="/Images/Get/10">
<input type="submit" value="Delete">
</form>其中5项Id和10项镜像id。所以这是预料之中的，而且是正确的。
<img src="/Images/Get/10">而这不是。使用项目Id而不是id (ItemImageViewModel.id)
action="/Images/Delete/5"我不知道为什么@Model.Id会在同一个子视图上生成不同的ids。
Edit1：
public class ItemImageViewModel
{
[BindProperty]
public int Id { get; set; }
public string Title { get; set; }
public int ItemId { get; set; }
}
public class ItemViewModel
{
public ItemViewModel()
{
}
public ItemViewModel(ItemViewModel vm)
{
Id = vm.Id;
Title = vm.Title;
ImageViewModels = vm.ImageViewModels;
}
public int Id { get; set; }
public string Title { get; set; }
public IEnumerable<ItemImageViewModel> ImageViewModels { get; set; }
}我已经删除了不相关的字段。调试器显示正常

现在，这段奇怪的代码生成了它应该生成的内容
<form action="@Url.Action("Delete", "Images", new { id = Model.Id })" method="post">
<input type="hidden" id="Id" name="Id" value="@Html.DisplayFor(m => Model.Id)" />
@Html.HiddenFor(m => Model.ItemId)"
<img src="@Url.Action("Get", "Images", new { id = Model.Id })" />
<input type="text" asp-for="@Model.Title" />
<input type="submit" value="Delete" />
</form>
<form action="/Images/Delete/10" method="post" novalidate="novalidate">
<input type="hidden" id="Id" name="Id" value="10">
<input data-val="true" data-val-required="The ItemId field is required." id="ItemId" name="ItemId" type="hidden" value="5">"
<img src="/Images/Get/10">
<input type="text" id="Title" name="Title" value="Jacket">
<input type="submit" value="Delete">
</form>
