C# 是否可以在ASP.NET中有一个与4个SQL表链接的创建页面，以使其更方便用户？

我正在使用C#、MVC和实体框架创建一个网站，该网站将显示数据并将数据输入车辆数据库。到目前为止，我已经为每个表控制器创建了一个页面。是否可以有一个创建页面显示并允许用户输入数据，而无需转到控制器的每个不同创建页面？这就是我要找的。但是，因为它只是我在SQLServerExpress中创建的一个视图，所以它是只读的，我无法对其进行写入

这就是我想要实现的，这样输入数据的方式更加用户友好

这就是当我从我的VehicleView控制器打开索引页时的样子

namespace VehiclesFinal.Controllers
{
    public class VehiclesViewsController : Controller
    {
        private DataConnection db = new DataConnection();

        // GET: VehiclesViews
        public ActionResult Index()
        {
            return View(db.VehiclesViews.ToList());
        }

        // GET: VehiclesViews/Details/5
        public ActionResult Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        // GET: VehiclesViews/Create
        public ActionResult Create()
        {
            return View();
        }

        // POST: VehiclesViews/Create
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see https://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include = "VehicleId,Year,Price,Cost,Name,Model,Type,EngineSize,Transmission,NumberOfDoors,Colour,SoldDate")] VehiclesView vehiclesView)
        {
            if (ModelState.IsValid)
            {
                db.VehiclesViews.Add(vehiclesView);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(vehiclesView);
        }

        // GET: VehiclesViews/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        // POST: VehiclesViews/Edit/5
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see https://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit([Bind(Include = "VehicleId,Year,Price,Cost,Name,Model,Type,EngineSize,Transmission,NumberOfDoors,Colour,SoldDate")] VehiclesView vehiclesView)
        {
            if (ModelState.IsValid)
            {
                db.Entry(vehiclesView).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(vehiclesView);
        }

        // GET: VehiclesViews/Delete/5
        public ActionResult Delete(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        // POST: VehiclesViews/Delete/5
        [HttpPost, ActionName("Delete")]
        [ValidateAntiForgeryToken]
        public ActionResult DeleteConfirmed(int id)
        {
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            db.VehiclesViews.Remove(vehiclesView);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }
    }
}

这就是我创建视图的位置和方式，以便用户只看到他们正在查找的信息

这是我在VehicleViewController中的代码

namespace VehiclesFinal.Controllers
{
    public class VehiclesViewsController : Controller
    {
        private DataConnection db = new DataConnection();

        // GET: VehiclesViews
        public ActionResult Index()
        {
            return View(db.VehiclesViews.ToList());
        }

        // GET: VehiclesViews/Details/5
        public ActionResult Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        // GET: VehiclesViews/Create
        public ActionResult Create()
        {
            return View();
        }

        // POST: VehiclesViews/Create
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see https://go.microsoft.com/fwlink/?LinkId=317598.

        public ActionResult Create([Bind(Include = "VehicleId,Year,Price,Cost,Name,Model,Type,EngineSize,Transmission,NumberOfDoors,Colour,SoldDate")] VehiclesView vehiclesView)
        {
            if (ModelState.IsValid)
            {
                db.VehiclesViews.Add(vehiclesView);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(vehiclesView);
        }

        // GET: VehiclesViews/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        // POST: VehiclesViews/Edit/5
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see https://go.microsoft.com/fwlink/?LinkId=317598.

        public ActionResult Edit([Bind(Include = "VehicleId,Year,Price,Cost,Name,Model,Type,EngineSize,Transmission,NumberOfDoors,Colour,SoldDate")] VehiclesView vehiclesView)
        {
            if (ModelState.IsValid)
            {
                db.Entry(vehiclesView).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(vehiclesView);
        }

        // GET: VehiclesViews/Delete/5
        public ActionResult Delete(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            VehiclesView vehiclesView = db.VehiclesViews.Find(id);
            if (vehiclesView == null)
            {
                return HttpNotFound();
            }
            return View(vehiclesView);
        }

        }

        protected override void Dispose(bool disposing)
        {

            }
            base.Dispose(disposing);
        }
    }
}

当然，这是可能的。创建包含所需所有数据字段的视图模型。填充视图模型，并将其发送到视图。允许编辑字段并在其上抛出保存按钮。表单将其全部发回控制器。在控制器操作中，您需要进行多次保存以更新每个表，但这并不是什么大问题。因此，由于我的视图已经有了一个控制器，我只需要找出一种方法来将更改保存到4个不同表的控制器操作中？您不需要为每个数据库表使用单独的控制器。例如，AccountController将处理有关用户及其帐户的所有信息，这些信息可能跨越多个表。在控制器操作中，您应该（如果您正确设置了表单等）了解您需要了解的所有信息。然后，根据更新的信息对模型进行适当的更改，并执行db保存。这就是实体框架的全部功能。
