本篇内容主要讲解“Asp.Net MVC4.0如何开发栏目内容模型管理”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Asp.Net MVC4.0如何开发栏目内容模型管理”吧!
网站后台中有栏目管理功能，对栏目管理中有栏目内容模块项，比如我们把网站的每个栏目划分为新闻模块、图片模块、文章模块、产品模块等。
栏目的模型类别管理包括模块名称、模块类型、是否启用、描述等。
一、Models属性：
using System.Linq;
using System.Web;
namespace Hillstone.Models
{
public class SysCategoryModel
{
[Key]
public int ModelID { get; set; }
[Display(Name="模型名称")]
[Required(ErrorMessage="×")]
[StringLength(50,ErrorMessage="×")]
public string ModelName { get; set; }
[Display(Name = "模型类型")]
[Required(ErrorMessage = "×")]
[StringLength(50, ErrorMessage = "×")]
public string ModelType { get; set; }
[Display(Name="是否启用")]
[Required(ErrorMessage = "×")]
public bool Enable{ get; set; }
[Display(Name="模型描述")]
[StringLength(100,ErrorMessage="×")]
public string Description{ get; set; }
}
}是否启用：如果不启用，那么在此类型的栏目将不能使用。
二、DAL数据层：访问或设置实体数据集
public DbSet<SysCategoryModel> categoryModel { get; set; }三、BLL业务逻辑层：读取、新增、编辑、删除、查看功能
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Hillstone.Models;
using System.Data.Entity;
using Hillstone.DAL;
namespace Hillstone.BLL
{
public class SysCategoryModelReponsitory : IRepositoryBase<SysCategoryModel>
{
private HillstoneContext db = new HillstoneContext();
/// <summary>
/// 读取模块列表
/// </summary>
/// <returns></returns>
public IQueryable<SysCategoryModel> List()
{
var _categoryModel = db.categoryModel;
return _categoryModel;
}
/// <summary>
/// 读取一条模块数据
/// </summary>
/// <param name="Id"></param>
/// <returns></returns>
public override SysCategoryModel Find(int Id)
{
var _categoryModel = db.categoryModel.SingleOrDefault(c => c.ModelID == Id);
return _categoryModel;
}
/// <summary>
/// 添加一条模块数据
/// </summary>
/// <param name="Tmodel"></param>
/// <returns></returns>
public override bool Add(SysCategoryModel Tmodel)
{
db.categoryModel.Add(Tmodel);
if (db.SaveChanges() > 0)
{
return true;
}
else {
return false;
}
}
/// <summary>
/// 删除一条模块数据
/// </summary>
/// <param name="Id">ID</param>
/// <returns></returns>
public override bool Delete(int Id)
{
var _categoryModel = db.categoryModel.FirstOrDefault(c => c.ModelID == Id);
if (_categoryModel != null)
{
return Delete(_categoryModel);
}
else {
return false;
}
}
/// <summary>
/// 删除一条模块数据
/// </summary>
/// <param name="sysCategoryModel">数据模型</param>
/// <returns></returns>
public bool Delete( SysCategoryModel sysCategoryModel)
{
db.categoryModel.Remove(sysCategoryModel);
if (db.SaveChanges() > 0)
{
return true;
}
else
{
return false;
}
}
/// <summary>
/// 修改模块数据
/// </summary>
/// <param name="Tmodel">模块数据模型</param>
/// <returns></returns>
public override bool Update(SysCategoryModel Tmodel)
{
db.categoryModel.Attach(Tmodel);
db.Entry<SysCategoryModel>(Tmodel).State = System.Data.Entity.EntityState.Modified;
if(db.SaveChanges()>0){
return true;
}
else
{
return false;
}
}
}
}注意：在编辑的时候要引用
using System.Data.Entity;
才能使用
db.Entry<SysCategoryModel>(Tmodel).State = System.Data.Entity.EntityState.Modified;
四、控制器：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Hillstone.BLL;
using Hillstone.Models;
namespace Hillstone.Controllers.Sys.Cotegory
{
public class CategoryModelController : Controller
{
private SysCategoryModelReponsitory categoryModelRsy = new SysCategoryModelReponsitory();
/// <summary>
/// 列表页面
/// </summary>
/// <returns></returns>
public ActionResult List()
{
var _categoryModel = categoryModelRsy.List();
return View(_categoryModel);
}
/// <summary>
/// 添加页面
/// </summary>
/// <returns></returns>
public ActionResult Create()
{
return View();
}
/// <summary>
/// 提交添加页面
/// </summary>
/// <param name="sysCategoryModel"></param>
/// <returns></returns>
[HttpPost]
public ActionResult Create(SysCategoryModel sysCategoryModel)
{
if (ModelState.IsValid)
{
if (categoryModelRsy.Add(sysCategoryModel))
{
ModelState.AddModelError("Message", "成功!");
}
else
{
ModelState.AddModelError("Message", "失败!");
}
}
return View();
}
/// <summary>
/// 编辑页面
/// </summary>
/// <returns></returns>
public ActionResult Edit(int id)
{
var categoryModel = categoryModelRsy.Find(id);
return View(categoryModel);
}
/// <summary>
/// 提交编辑页面
/// </summary>
/// <param name="sysCategoryModel"></param>
/// <returns></returns>
[HttpPost]
public ActionResult Edit(SysCategoryModel sysCategoryModel)
{
if (ModelState.IsValid) {
if (categoryModelRsy.Update(sysCategoryModel))
{
ModelState.AddModelError("Message", "成功！");
}
else {
ModelState.AddModelError("Message","失败！");
}
}
return View();
}
/// <summary>
/// 查看页面
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public ActionResult Details(int id)
{
var _sysCategoryModel = categoryModelRsy.Find(id);
return View(_sysCategoryModel);
}
/// <summary>
/// 删除一条模块
/// </summary>
/// <param name="id">ID</param>
/// <returns></returns>
[HttpPost]
public ActionResult Delete(int id)
{
if (categoryModelRsy.Delete(id))
{
return new HttpStatusCodeResult(System.Net.HttpStatusCode.OK);
}
else
{
return new HttpStatusCodeResult(System.Net.HttpStatusCode.NotFound);
}
}
//AJAX删除功能
[HttpPost]
public JsonResult DeleteAsJson(int id)
{
var _categoryModel = categoryModelRsy.Find(id);
if (categoryModelRsy != null)
{
return Json(categoryModelRsy.Delete(id);
}
else
{
return Json(false);
}
}
}
} 五、视图页面
1、显示列表：主要是Json删除功能的实现
@model IEnumerable<Hillstone.Models.SysCategoryModel>
@{
ViewBag.Title = "List";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@section Scripts{
@Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
function DeleteAsJson(id,name)
{
if (confirm("你确认要删除" + name + "?")) {
$.post("@Url.Action("DeleteAsJson","CategoryModel")", { Id: id }, function (data) {
if (data) {
alert("删除成功!");
location.reload();
}
})
}
}
@* $("#btn_del").click(function () {
if (confirm("您确定要删除改栏目吗？\n如该栏目有子栏目请先删除子栏目！")) {
$.post("@Url.Action("ManageDeleteJson","Category")", { id: $("#CategoryId").val() }, function (data) {
if (data) {
alert("成功删除栏目！");
top.location = "@Url.Action("Manage", "Category")";
}
else {
alert("删除栏目失败！如该栏目有子栏目请先删除子栏目。");
}
});
}
});*@
</script>
}
<h3>List</h3>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th>
@Html.DisplayNameFor(model => model.ModelName)
</th>
<th>
@Html.DisplayNameFor(model => model.ModelType)
</th>
<th>
@Html.DisplayNameFor(model => model.Enable)
</th>
<th>
@Html.DisplayNameFor(model => model.Description)
</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.ModelName)
</td>
<td>
@Html.DisplayFor(modelItem => item.ModelType)
</td>
<td>
@Html.DisplayFor(modelItem => item.Enable)
</td>
<td>
@Html.DisplayFor(modelItem => item.Description)
</td>
<td>
@Html.ActionLink("编辑", "Edit", new { id=item.ModelID })
@Html.ActionLink("查看", "Details", new { id=item.ModelID }) |
<a id="btn_del" href="javascript:void(0)" onclick="DeleteAsJson(@item.ModelID,'@item.ModelName')">删除</a>
</td>
</tr>
}
</table>其他页面基本保持不变。
