如何显示所选汽车的详细信息视图
本文关键字:汽车 详细信息 视图 何显示 显示 | 更新日期: 2023-09-27 18:26:13
我是ASP.NET MVC 5的新手。
我已经生成了车库的视图详细信息。
@model TestApp.Models.Garage
@{
ViewBag.Title = "Details";
}
<h2>Details</h2>
<div>
<h4>Category</h4>
<hr />
<dl class="dl-horizontal">
<dt>
@Html.DisplayNameFor(model => model.Name)
</dt>
<dd>
@Html.DisplayFor(model => model.Name)
</dd>
<dt>
@Html.DisplayNameFor(model => model.Description)
</dt>
<dd>
@Html.DisplayFor(model => model.Description)
</dd>
</dl>
<hr />
<div>Cars of garage</div>
<div>
@foreach (var item in Model.Cars)
{
<li>@Html.ActionLink(@item.Name, "Details", "Cars")</li> // should be correct code line
}
</div>
<hr />
</div>
<p>
@Html.ActionLink("Edit", "Edit", new { id = Model.GarageID }) |
@Html.ActionLink("Back to List", "Index") |
@Html.ActionLink("Add Car", "Create", "Cars")
</p>
我想显示车库的汽车列表,用户可以点击一些汽车并查看这辆车的详细信息。但我找不到@Html.ActionLink(@item.Name,"Details","Cars")方法的正常接口。
public class CarsController : Controller
{
private TestDBContext db = new TestDBContext();
public async Task<ActionResult> Index()
{
var cars = db.Cars.Include(p => p.Category);
return View(await cars.ToListAsync());
}
public async Task<ActionResult> Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Cars car = await db.Cars.FindAsync(id);
if (car == null)
{
return HttpNotFound();
}
return View(cars);
}
public ActionResult Create()
{
ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name");
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Create([Bind(Include="CarID,Name,Description, GarageID")] Car car)
{
if (ModelState.IsValid)
{
db.Cars.Add(car);
await db.SaveChangesAsync();
return RedirectToAction("Index");
}
ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID);
return View(car);
}
public async Task<ActionResult> Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Car car = await db.Cars.FindAsync(id);
if (car == null)
{
return HttpNotFound();
}
ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID);
return View(car);
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Edit([Bind(Include="CarID,Name,Description,GarageID")] Car car)
{
if (ModelState.IsValid)
{
db.Entry(car).State = EntityState.Modified;
await db.SaveChangesAsync();
return RedirectToAction("Index");
}
ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID);
return View(car);
}
public async Task<ActionResult> Delete(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Car car = await db.Cars.FindAsync(id);
if (car == null)
{
return HttpNotFound();
}
return View(car);
}
[HttpPost, ActionName("Delete")]
[ValidateAntiForgeryToken]
public async Task<ActionResult> DeleteConfirmed(int id)
{
Cars car = await db.Cars.FindAsync(id);
db.Cars.Remove(car);
await db.SaveChangesAsync();
return RedirectToAction("Index");
}
}
您需要在ActionLink中添加一个可为null的参数,以便CarsController知道如何导航到Details方法,如下所示:
@Html.ActionLink(item.Name, "Details", "Cars", new { id = item.Id }, null)
