1.实现UI端的增删改查

1.1添加增删改查代码

打开SimpleTaskSystem.sln解决方案，添加一个“包含视图的MVC 5控制器（使用EntityFramework）”TaskController控制器，添加成功后我们就能得到一个完整增删改查的功能了。

生成的代码是不能用在我们的这个示例里的，还需经过些许调整，经过调整后的代码如下：

using System;using System.Net;using System.Web.Mvc;using SimpleTaskSystem.Services;namespace SimpleTaskSystem.Web.Controllers{    public class TaskController : SimpleTaskSystemControllerBase    {        private readonly ITaskAppService _taskService;        public TaskController(ITaskAppService taskService)        {            _taskService = taskService;        }        // GET: Task        public ActionResult Index(GetTasksInput input)        {            var tasks = _taskService.GetTasks(input);            return View(tasks);        }        // GET: Task/Details/5        public ActionResult Details(long? id)        {            if (id == null)            {                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);            }            var task = _taskService.GetTask(id.Value);            if (task == null)            {                return HttpNotFound();            }            return View(task);        }        // GET: Task/Create        public ActionResult Create()        {            return View();        }        // POST: Task/Create        [HttpPost]        [ValidateAntiForgeryToken]        public ActionResult Create(CreateTaskInput input)        {            if (ModelState.IsValid)            {                _taskService.CreateTask(input);                return RedirectToAction("Index");            }            return View(input);        }        // GET: Task/Edit/5        public ActionResult Edit(long? id)        {            if (id == null)            {                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);            }            var task = _taskService.GetTask(id.Value);            if (task == null)            {                return HttpNotFound();            }            return View(task);        }        // POST: Task/Edit/5        [HttpPost]        [ValidateAntiForgeryToken]        public ActionResult Edit(TaskDto dto)        {            if (ModelState.IsValid)            {                var input = new UpdateTaskInput();                input.Id = dto.Id;                input.Description = dto.Description;                _taskService.UpdateTask(input);                return RedirectToAction("Index");            }            return View(dto);        }        // GET: Task/Delete/5        public ActionResult Delete(long? id)        {            if (id == null)            {                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);            }            var task = _taskService.GetTask(id.Value);            if (task == null)            {                return HttpNotFound();            }            return View(task);        }        // POST: Task/Delete/5        [HttpPost, ActionName("Delete")]        [ValidateAntiForgeryToken]        public ActionResult DeleteConfirmed(long id)        {            throw new Exception("请大家自行实现该方法！");        }    }}

1.2.依次调整Views/Task下面的.cshtml文件

Index.cshtml

@model SimpleTaskSystem.Services.GetTasksOutput@{    ViewBag.Title = "Index";}<h2>任务列表</h2><p>    @Html.ActionLink("Create New", "Create")</p><table class="table">    <tr>        <th>            任务描述        </th>        <th></th>    </tr>@foreach (var item in Model.Tasks) {    <tr>        <td>            @Html.DisplayFor(modelItem => item.Description)        </td>        <td>            @Html.ActionLink("Edit", "Edit", new { id=item.Id }) |            @Html.ActionLink("Details", "Details", new { id=item.Id }) |            @Html.ActionLink("Delete", "Delete", new { id=item.Id })        </td>    </tr>}</table>

Create.cshtml

@model SimpleTaskSystem.Services.CreateTaskInput@{    ViewBag.Title = "Create";}<h2>Create</h2>@using (Html.BeginForm()) {    @Html.AntiForgeryToken()    <div class="form-horizontal">        <h4>TaskDto</h4>        <hr />        @Html.ValidationSummary(true, "", new { @class = "text-danger" })        <div class="form-group">            @Html.LabelFor(model => model.Description, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.EditorFor(model => model.Description, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.Description, "", new { @class = "text-danger" })            </div>        </div>        <div class="form-group">            <div class="col-md-offset-2 col-md-10">                <input type="submit" value="http://www.mamicode.com/Create" class="btn btn-default" />            </div>        </div>    </div>}<div>    @Html.ActionLink("Back to List", "Index")</div>

Edit.cshtml

@model SimpleTaskSystem.Services.TaskDto@{    ViewBag.Title = "Edit";}<h2>Edit</h2>@using (Html.BeginForm()){    @Html.AntiForgeryToken()    <div class="form-horizontal">        <h4>TaskDto</h4>        <hr />        @Html.ValidationSummary(true, "", new { @class = "text-danger" })        @Html.HiddenFor(model => model.Id)        <div class="form-group">            @Html.LabelFor(model => model.Description, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.EditorFor(model => model.Description, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.Description, "", new { @class = "text-danger" })            </div>        </div>        @*<div class="form-group">            @Html.LabelFor(model => model.AssignedUserId, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.EditorFor(model => model.AssignedUserId, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.AssignedUserId, "", new { @class = "text-danger" })            </div>        </div>        <div class="form-group">            @Html.LabelFor(model => model.State, htmlAttributes: new { @class = "control-label col-md-2" })            <div class="col-md-10">                @Html.EditorFor(model => model.State, new { htmlAttributes = new { @class = "form-control" } })                @Html.ValidationMessageFor(model => model.State, "", new { @class = "text-danger" })            </div>        </div>*@        <div class="form-group">            <div class="col-md-offset-2 col-md-10">                <input type="submit" value="http://www.mamicode.com/Save" class="btn btn-default" />            </div>        </div>    </div>}<div>    @Html.ActionLink("Back to List", "Index")</div>

Details.cshtml

@model SimpleTaskSystem.Services.TaskDto@{    ViewBag.Title = "Details";}<h2>Details</h2><div>    <h4>TaskDto</h4>    <hr />    <dl class="dl-horizontal">        <dt>            @Html.DisplayNameFor(model => model.Description)        </dt>        <dd>            @Html.DisplayFor(model => model.Description)        </dd>        <dt>            @Html.DisplayNameFor(model => model.AssignedUserId)        </dt>        <dd>            @Html.DisplayFor(model => model.AssignedUserId)        </dd>        <dt>            @Html.DisplayNameFor(model => model.State)        </dt>        <dd>            @Html.DisplayFor(model => model.State)        </dd>    </dl></div><p>    @Html.ActionLink("Edit", "Edit", new { id = Model.Id }) |    @Html.ActionLink("Back to List", "Index")</p>

1.3.导航栏增加【任务管理】菜单

打开App_Start/SimpleTaskSystemNavigationProvider.cs文件添加菜单

using Abp.Application.Navigation;using Abp.Localization;namespace SimpleTaskSystem.Web{    /// <summary>    /// This class defines menus for the application.    /// It uses ABP‘s menu system.    /// When you add menu items here, they are automatically appear in angular application.    /// See .cshtml and .js files under App/Main/views/layout/header to know how to render menu.    /// </summary>    public class SimpleTaskSystemNavigationProvider : NavigationProvider    {        public override void SetNavigation(INavigationProviderContext context)        {            context.Manager.MainMenu                .AddItem(                    new MenuItemDefinition(                        "Home",                        new LocalizableString("HomePage", SimpleTaskSystemConsts.LocalizationSourceName),                        url: "#/",                        icon: "fa fa-home"                        )                ).AddItem(                    new MenuItemDefinition(                        "About",                        new LocalizableString("About", SimpleTaskSystemConsts.LocalizationSourceName),                        url: "#/about",                        icon: "fa fa-info"                        )                ).AddItem(                    new MenuItemDefinition(                        "About",                        new LocalizableString("Task Manage", SimpleTaskSystemConsts.LocalizationSourceName),                        url: "/task/"                        )                );        }    }}

2.浏览器中测试

刷新浏览器，进行增删改查测试。

3.本节源码下载

相对前一节的代码，本节代码除上面的代码外还有些许调整，请大家在这里下载完整版源码：http://pan.baidu.com/s/1c2n2U7Q

Abp基础的部分我们已经学习完了，到这你应该学会了使用Abp进行基本的增删改查，后面我们会通过项目实战的方式来讲解Abp其它功能的用法，请大家继续关注www.webplus.org.cn
