ABP进阶教程3 - 优化编辑

点这里进入ABP进阶教程目录 

我们尝试在新增/编辑界面增加一个下拉框用来代替输入框编辑Status
  

添加实体

打开领域层(即JD.CRS.Core)的Entitys目录 //用以存放实体对象
添加一个类StatusCode.cs //状态信息

using System;
using System.Collections.Generic;
using System.Text;

namespace JD.CRS.Entitys
{
    public enum StatusCode : byte
    {
        Enabled = 0,
        Disabled = 1
    }
}

更新模型

更新查询视图模型

打开展示层(即JD.CRS.Web.Mvc)的Models/Course/CourseListViewModel.cs //Course查询视图模型

新增GetStatusList方法 //获取状态列表

 1 public StatusCode? Status { get; set; }
 2 
 3 public List GetStatusList(ILocalizationManager localizationManager)
 4 {
 5     var list = new List
 6     {
 7         new SelectListItem
 8         {
 9             Text = localizationManager.GetString(CRSConsts.LocalizationSourceName, "PleaseSelect"),
10             Value = "",
11             Selected = Status == null
12         }
13     };
14 
15     list.AddRange(Enum.GetValues(typeof(StatusCode))
16         .Cast()
17         .Select(status =>
18             new SelectListItem
19             {
20                 Text = localizationManager.GetString(CRSConsts.LocalizationSourceName, $"StatusCode_{status}"),
21                 Value = status.ToString(),
22                 Selected = status == Status
23             })
24     );
25 
26     return list;
27 }

View Code

更新编辑视图模型

打开展示层(即JD.CRS.Web.Mvc)的Models/Course/EditCourseModalViewModel.cs //Course编辑视图模型

新增GetStatusList方法 //获取状态列表

 1 public List GetStatusList(ILocalizationManager localizationManager)
 2 {
 3     var list = new List
 4     {
 5     };
 6 
 7     list.AddRange(Enum.GetValues(typeof(StatusCode))
 8         .Cast()
 9         .Select(status =>
10             new SelectListItem
11             {
12                 Text = localizationManager.GetString(CRSConsts.LocalizationSourceName, $"StatusCode_{status}"),
13                 Value = status.ToString(),
14                 Selected = status == Status
15             })
16     );
17 
18     return list;
19 }

View Code

更新控制器

打开展示层(即JD.CRS.Web.Mvc)的Controllers/CourseController.cs //Course控制器

更新EditCourseModal方法 //向EditCourseModalViewModel传参数Status

public async Task EditCourseModal(int courseId)
{
    var course = await _courseAppService.Get(new EntityDto<int>(courseId));
    var model = new EditCourseModalViewModel
    {
        Course = course,
        Status = course.Status
    };
    return View("_EditCourseModal", model);
}

更新创建视图

打开展示层(即JD.CRS.Web.Mvc)的Views/Course/Index.cshtml //Course查询视图

添加下拉框Status //以替代输入框Status

<div class="row clearfix">
    <div class="col-sm-12">
        <div class="form-line">
            <label class="form-label">@L("Status")label>
            @Html.DropDownListFor(
            model => model.Status,
            Model.GetStatusList(LocalizationManager),
            new
            {
                @class = "form-control",
                id = "Status"
            })
            @*<input name="Status" type="text" class="form-control" />*@
        div>
    div>
div>

更新编辑视图

打开展示层(即JD.CRS.Web.Mvc)的Views/Course/_EditCourseModal.cshtml //Course编辑视图

添加下拉框Status //以替代输入框Status

<div class="row clearfix">
    <div class="col-sm-12">
        <div class="form-line">
            <label class="form-label">@L("Status")label>
            @Html.DropDownListFor(
            model => model.Status,
            Model.GetStatusList(LocalizationManager),
            new
            {
                @class = "form-control",
                id = "Status"
            })
            @*<input name="Status" type="text" value="@Model.Course.Status" class="form-control" />*@
        div>
    div>
div>

更新脚本

打开展示层(即JD.CRS.Web.Mvc)的\wwwroot\view-resources\Views\Course\_EditCourseModal.js //用以存放Course编辑相关脚本

在初始化Form时给下拉框传值

//Initial form
_$modal.on('shown.bs.modal', function () {
    _$form.find('input[type=text]:first').focus();//focus first input
    _$status.val() = status;//Status value
});
