ABP学习入门系列（五）（展示实现增删改查）
大致要实现的 效果如下
1，添加Controller（用到的X.PagedList 注意到nuget添加）
using System.Web.Mvc;
using Abp.Application.Services.Dto;
using Abp.Runtime.Caching;
using Abp.Threading;
using Abp.Web.Mvc.Authorization;
using AutoMapper;
using LearningMpaAbp.Notifications;
using LearningMpaAbp.Tasks;
using LearningMpaAbp.Tasks.Dtos;
using LearningMpaAbp.Users;
using LearningMpaAbp.Users.Dto;
using LearningMpaAbp.Web.Models.Tasks;
using X.PagedList;
namespace LearningMpaAbp.Web.Controllers
{
[AbpMvcAuthorize]
public class TasksController : LearningMpaAbpControllerBase
{
private readonly ITaskAppService _taskAppService;
private readonly IUserAppService _userAppService;
private readonly INotificationAppService _notificationAppService;
private readonly ICacheManager _cacheManager;
public TasksController(ITaskAppService taskAppService, IUserAppService userAppService, ICacheManager cacheManager, INotificationAppService notificationAppService)
{
_taskAppService = taskAppService;
_userAppService = userAppService;
_cacheManager = cacheManager;
_notificationAppService = notificationAppService;
}
public ActionResult Index(GetTasksInput input)
{
var output = _taskAppService.GetTasks(input);
var model = new IndexViewModel(output.Tasks)
{
SelectedTaskState = input.State
};
return View(model);
}
// GET: Tasks
public ActionResult PagedList(int? page)
{
//每页行数
var pageSize = 5;
var pageNumber = page ?? 1; //第几页
var filter = new GetTasksInput
{
SkipCount = (pageNumber - 1) * pageSize, //忽略个数
MaxResultCount = pageSize
};
var result = _taskAppService.GetPagedTasks(filter);
//已经在应用服务层手动完成了分页逻辑，所以需手动构造分页结果
var onePageOfTasks = new StaticPagedList<TaskDto>(result.Items, pageNumber, pageSize, result.TotalCount);
//将分页结果放入ViewBag供View使用
ViewBag.OnePageOfTasks = onePageOfTasks;
return View();
}
public PartialViewResult GetList(GetTasksInput input)
{
var output = _taskAppService.GetTasks(input);
return PartialView("_List", output.Tasks);
}
/// <summary>
/// 获取创建任务分部视图
/// 该方法使用ICacheManager进行缓存，在WebModule中配置缓存过期时间为10mins
/// </summary>
/// <returns></returns>
public PartialViewResult RemoteCreate()
{
//1.1 注释该段代码，使用下面缓存的方式
//var userList = _userAppService.GetUsers();
//1.2 同步调用异步解决方案（最新Abp创建的模板项目已经去掉该同步方法，所以可以通过下面这种方式获取用户列表）
//var userList = AsyncHelper.RunSync(() => _userAppService.GetUsersAsync());
//1.3 缓存版本
var userList = _cacheManager.GetCache("ControllerCache").Get("AllUsers", () => _userAppService.GetUsers());
//1.4 转换为泛型版本
//var userList = _cacheManager.GetCache("ControllerCache").AsTyped<string, ListResultDto<UserListDto>>().Get("AllUsers", () => _userAppService.GetUsers());
//1.5 泛型缓存版本
//var userList = _cacheManager.GetCache<string, ListResultDto<UserListDto>>("ControllerCache").Get("AllUsers", () => _userAppService.GetUsers());
ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name");
return PartialView("_CreateTaskPartial");
}
/// <summary>
/// 获取创建任务分部视图（子视图）
/// 该方法使用[OutputCache]进行缓存，缓存过期时间为2mins
/// </summary>
/// <returns></returns>
[ChildActionOnly]
[OutputCache(Duration = 1200, VaryByParam = "none")]
public PartialViewResult Create()
{
var userList = _userAppService.GetUsers();
ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name");
return PartialView("_CreateTask");
}
// POST: Tasks/Create

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(CreateTaskInput task)
{
var id = _taskAppService.CreateTask(task);
var input = new GetTasksInput();
var output = _taskAppService.GetTasks(input);
return PartialView("_List", output.Tasks);
}
// GET: Tasks/Edit/5
public PartialViewResult Edit(int id)
{
var task = _taskAppService.GetTaskById(id);
var updateTaskDto = Mapper.Map<UpdateTaskInput>(task);
var userList = _userAppService.GetUsers();
ViewBag.AssignedPersonId = new SelectList(userList.Items, "Id", "Name", updateTaskDto.AssignedPersonId);
return PartialView("_EditTask", updateTaskDto);
}
// POST: Tasks/Edit/5
// 为了防止“过多发布”攻击，请启用要绑定到的特定属性，有关
// 详细信息，请参阅 http://go.microsoft.com/fwlink/?LinkId=317598。
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(UpdateTaskInput updateTaskDto)
{
_taskAppService.UpdateTask(updateTaskDto);
var input = new GetTasksInput();
var output = _taskAppService.GetTasks(input);
return PartialView("_List", output.Tasks);
}
public ActionResult NotifyUser()
{
_notificationAppService.NotificationUsersWhoHaveOpenTask();
return new EmptyResult();
}
}
}
2，视图
@using Abp.Web.Mvc.Extensions @model LearningMpaAbp.Web.Models.Tasks.IndexViewModel @{ ViewBag.Title = L("TaskList"); ViewBag.ActiveMenu = "TaskList"; //Matches with the menu name in SimpleTaskAppNavigationProvider to highlight the menu item } @section scripts{ @Html.IncludeScript("~/Views/Tasks/index.js"); } <h2> @L("TaskList") <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#add">Create Task</button> <a class="btn btn-primary" data-toggle="modal" href="@Url.Action("RemoteCreate")" data-target="#modal" role="button">（Create Task）使用Remote方式调用Modal进行展现</a> <a class="btn btn-success" href="@Url.Action("PagedList")" role="button">分页展示</a> <button type="button" class="btn btn-info" onclick="notifyUser();">通知未完成任务的用户</button> <!--任务清单按照状态过滤的下拉框--> <span class="pull-right"> @Html.DropDownListFor( model => model.SelectedTaskState, Model.GetTaskStateSelectListItems(), new { @class = "form-control select2", id = "TaskStateCombobox" }) </span> </h2> <!--任务清单展示--> <div class="row" id="taskList"> @{ Html.RenderPartial("_List", Model.Tasks); } </div> <!--通过初始加载页面的时候提前将创建任务模态框加载进来--> @Html.Action("Create") <!--编辑任务模态框通过ajax动态填充到此div中--> <div id="edit"> </div> <!--Remote方式弹出创建任务模态框--> <div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="createTask" data-backdrop="static"> <div class="modal-dialog" role="document"> <div class="modal-content"> </div> </div> </div>
另外还有_createTaskPartial，_EditTaskPartial 等，这里就不贴代码了
以上。。。
