我已经为数据库中的单个表（例如电影数据库）开发了CRUD应用程序。我想通过sql查询将不同表的指定列显示出来。并且在插入或编辑选项时，所有表都必须自动更新。
namespace AnimeshDB.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
public partial class Animesh
{
public int ID { get; set; }
[Required(ErrorMessage = "this feild is required")]
public string Name { get; set; }
[Required(ErrorMessage = "this feild is required")]
public int Year { get; set; }
public string Plot { get; set; }
public string Poster { get; set; }
}
}
这是我的观点。
@model AnimeshDB.Models.Animesh
@{
Layout = null;
}
@using (Html.BeginForm("AddOrEdit", "Movie", FormMethod.Post, new { onsubmit = "return SubmitForm(this)" }))
{
@Html.HiddenFor(model => model.ID)
@*<div class="form-group">
@Html.LabelFor(model => model.ID, new { @class="control-label"})
@Html.EditorFor(model => model.ID, new {htmlAttributes= new { @class="form-control" } })
</div>*@
<div class="form-group">
@Html.LabelFor(model => model.Name, new { @class = "control-label" })
@Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="form-group">
@Html.LabelFor(model => model.Year, new { @class = "control-label" })
@Html.EditorFor(model => model.Year, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Year)
</div>
<div class="form-group">
@Html.LabelFor(model => model.Plot, new { @class = "control-label" })
@Html.EditorFor(model => model.Plot, new { htmlAttributes = new { @class = "form-control" } })
</div>
<div class="form-group">
@Html.LabelFor(model => model.Poster, new { @class = "control-label" })
@Html.EditorFor(model => model.Poster, new { htmlAttributes = new { @class = "form-control" } })
</div>
<div class="form-group">
<input type="submit" value="Submit" class="btn btn-primary" />
<input type="reset" value="Reset" class="btn" />
</div>}
这是我的控制器
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using AnimeshDB.Models;
using System.Data.Entity.Validation;
using System.Data.Entity;
namespace AnimeshDB.Controllers
{
public class MovieController : Controller
{
// GET: Movie
public ActionResult Index()
{
return View();
}
public ActionResult GetData()
{
using (DBModel db = new DBModel())
{
List<Animesh> movList = db.Animeshes.ToList<Animesh>();
return Json(new { data = movList }, JsonRequestBehavior.AllowGet);
}
}
[HttpGet]
public ActionResult AddOrEdit(int id = 0)
{
if (id == 0)
return View(new Animesh());
else
{
using (DBModel db = new DBModel())
{
return View(db.Animeshes.Where(x => x.ID == id).FirstOrDefault<Animesh>());
}
}
}
[HttpPost]
public ActionResult AddOrEdit(Animesh mov)
{
using (DBModel db = new DBModel())
{
try
{
if (mov.ID == 0)
{
db.Animeshes.Add(mov);
db.SaveChanges();
return Json(new { success = true, message = "Saved Successfully!!" }, JsonRequestBehavior.AllowGet);
}
else
{
db.Entry(mov).State = EntityState.Modified;
db.SaveChanges();
return Json(new { success = true, message = "Updated Successfully!!" }, JsonRequestBehavior.AllowGet);
}
}
catch (DbEntityValidationException e)
{
foreach (var eve in e.EntityValidationErrors)
{
Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
eve.Entry.Entity.GetType().Name, eve.Entry.State);
foreach (var ve in eve.ValidationErrors)
{
Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
ve.PropertyName, ve.ErrorMessage);
}
}
throw;
}
}
}
[HttpPost]
public ActionResult Delete(int id)
{
using (DBModel db = new DBModel())
{
Animesh mov = db.Animeshes.Where(x => x.ID == id).FirstOrDefault<Animesh>();
db.Animeshes.Remove(mov);
db.SaveChanges();
return Json(new { success = true, message = "Deleted Successfully!!" }, JsonRequestBehavior.AllowGet);
}
}
}}
最后，这是我的Index.cshtml文件代码
