我想要一种方法,我可以显示外键的值,而不是显示一个数字。例如,我有以下视图来显示所有评论:
@model IEnumerable<Games.Models.tblReview>
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th>
ReviewID
</th>
<th>
Recomendation
</th>
<th>
AvoidOrBuy
</th>
<th>
Score
</th>
<th>
GameIDFK
</th>
<th>
UserName
</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.ReviewID)
</td>
<td>
@Html.DisplayFor(modelItem => item.Recomendation)
</td>
<td>
@Html.DisplayFor(modelItem => item.AvoidOrBuy)
</td>
<td>
@Html.DisplayFor(modelItem => item.Score)
</td>
<td>
@Html.DisplayFor(modelItem => item.GameIDFK)
</td>
<td>
@Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Details", "Details", new { id=item.ReviewID }) |
@Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
</td>
</tr>
}
</table>
我想要一种方式,其中GameIDFK显示游戏的名称,而不是我的控制器显示此信息是基本的数字将显示在这里:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Games.Models;
namespace Games.Controllers
{
public class ShowAllReviewsController : Controller
{
//
// GET: /ShowAllReviews/
public ActionResult Index()
{
using (var db = new gamezoneDBEntities())
{
return View(db.tblReviews.ToList());
}
}
//
// GET: /ShowAllReviews/Details/5
public ActionResult Details(int id)
{
return View();
}
//
// GET: /ShowAllReviews/Create
public ActionResult Create()
{
return View();
}
//
// POST: /ShowAllReviews/Create
[HttpPost]
public ActionResult Create(FormCollection collection)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
//
// GET: /ShowAllReviews/Edit/5
public ActionResult Edit(int id)
{
return View();
}
//
// POST: /ShowAllReviews/Edit/5
[HttpPost]
public ActionResult Edit(int id, FormCollection collection)
{
try
{
// TODO: Add update logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
//
// GET: /ShowAllReviews/Delete/5
public ActionResult Delete(int id)
{
return View();
}
//
// POST: /ShowAllReviews/Delete/5
[HttpPost]
public ActionResult Delete(int id, FormCollection collection)
{
try
{
// TODO: Add delete logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
}
}
有没有办法让我可以获得游戏外键,因为这个网站将用于新来的游戏玩家,我想知道哪些游戏很好玩,不希望用户点击评论,只看到一个号码,没有游戏名称。
你能帮忙吗
编辑:
我在视图中使用了以下内容:
@Html.DisplayFor(modelItem => item.tblGame.GameName)
但它崩溃并发出以下错误:
The ObjectContext instance has been disposed and can no longer be used for operations that require a connection.
编辑2:
namespace Games.Models
{
using System;
using System.Collections.Generic;
public partial class tblReview
{
public int ReviewID { get; set; }
public string Recomendation { get; set; }
public string AvoidOrBuy { get; set; }
public string Score { get; set; }
public int GameIDFK { get; set; }
public string UserName { get; set; }
public virtual tblGame tblGame { get; set; }
}
答案 0 :(得分:1)
您可能需要考虑using ViewModel classes,但我认为如果您修改控制器以使用类似
的内容 return View(db.tblReviews.Include("tblGame").ToList());
您可以在视图中使用该属性,如上所述。
