Question

我有一个名为＆＃34; Slider＆＃34;

的模型

using System;
using NHibernate.Mapping.ByCode;
using NHibernate.Mapping.ByCode.Conformist;

namespace BarMotors.Models
{
public class Slider
{
    public virtual int Id { get; set; }
    public virtual string Photo{ get; set; }
    public virtual string LeftText{ get; set; }
    public virtual string RightText { get; set; }
    public virtual int SortOrder{ get; set; }
    public virtual DateTime CreatedAt { get; set; }
    public virtual DateTime? UpdatedAt { get; set; }
    public virtual DateTime? DeletedAt { get; set; }

    public virtual bool IsDeleted
    {
        get { return DeletedAt != null; }
    }
}

public class SliderMap : ClassMapping<Slider>
{
    public SliderMap()
    {
        Table("Sliders");
        Id(x => x.Id, x => x.Generator(Generators.Identity));
        Property(x => x.Photo, x => x.NotNullable(true));
        Property(x => x.LeftText);
        Property(x => x.RightText);
        Property(x => x.SortOrder, x => x.NotNullable(true));
    }
}
}

我也（现在）有这个控制器;

using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using BarMotors.Models;
using NHibernate.Linq;

namespace BarMotors.Controllers
{
    public class SliderController : Controller
    {
        [ChildActionOnly]
        public ActionResult Sliders()
        {
            List<Slider> model;
            new List<Models.Slider>();
            model = Database.Session.Query<Slider>().Where(s => s.DeletedAt == null).OrderBy(x=>x.SortOrder).ToList();

            return PartialView("_HomeSlider", model);
        }
    }
}

主要观点

@{
    ViewBag.Title = "Homepage";
}
<h1>Homepage</h1>
@Html.Action("Sliders", "Slider")

部分视图

@model BarMotors.Models.Slider

@{
    Layout = null;
}
//do something in loop of Slider

在SliderController中我不能将var模型传递给局部视图我要么得到Iqueryable，ienumerable或者错误;

Models.Slider的LIST不能分配给models.Slider类型

非常感谢西蒙

如果滑块与父模型无关，则可能需要使用子操作。

你的控制器会有这样的动作：

public class MyController : Controller
{
    /* ... your code ... */

    [ChildActionOnly]
    public ActionResult Sliders()
    {
        var model = new Models.Slider();

        /* ... populate model ... */

        return PartialView("your-view-name", model);
    }
}

您可以使用HtmlHelper.Action()方法从父视图中请求子操作：

<div>
    <!-- more view markup ... -->

    @Html.Action("sliders", "my")

</div>

以这种方式调用Html.Action方法时，生成的视图（通常是部分视图）将在当前视图中就地呈现。如果您熟悉PHP，它有点类似于include语句。

您正在尝试将列表分配给模型，但您已声明了一个非列表类型的模型，因此您要么将其声明为列表类型，要么从结果中选择firstordefault

public class MyController : Controller
{
    /* ... your code ... */

    [ChildActionOnly]
    public ActionResult Sliders()
    {
        var model = new Models.Slider();

        model = Database.Session.Query<Slider>().Where(s => s.DeletedAt == null).OrderBy(x=>x.SortOrder).ToList().FirstOrDefault();

        return PartialView("your-view-name", model);
    }
}

否则

public class MyController : Controller
{
    /* ... your code ... */

    [ChildActionOnly]
    public ActionResult Sliders()
    {
        var model = new List<Models.Slider>();

        model = Database.Session.Query<Slider>().Where(s => s.DeletedAt == null).OrderBy(x=>x.SortOrder).ToList();

        return PartialView("your-view-name", model);
    }
}

在部分视图中，您必须将其更改为

@model List<BarMotors.Models.Slider>

@{
    Layout = null;
}

MVC 5部分视图 - 模型混淆
