接上一篇:ABP教程(三)- 开始一个简单的任务管理系统 – 后端编码

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="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="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)

        </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/"
                        )
                );
        }
    }
}
