ABP(7) - 更新和删除书籍 - 官方教程扫盲贴之Update和Delete的使用 （详细解说）

1 目标

• 1.1 更新书籍实体
• 1.2 增加下拉选项
• 1.3 删除实体

2 编辑更新已存在的 Book 实体

• 2.1 在 Acme.BookStore.Web 项目的 Pages/Books 目录下新建一个名叫 EditModal.cshtml 的Razor页面
• 2.2 替换以下代码, 在这里增加了,get方法, OnPost异步方法,也就是发送数据方法

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace Acme.BookStore.Web.Pages.Books
{
    public class EditModalModel : BookStorePageModel
    {
        [HiddenInput]
        [BindProperty(SupportsGet = true)]
        public Guid Id { get; set; }

        [BindProperty]
        public CreateUpdateBookDto Book { get; set; }

        private readonly IBookAppService _bookAppService;

        public EditModalModel(IBookAppService bookAppService)
        {
            _bookAppService = bookAppService;
        }

        public async Task OnGetAsync()
        {
            var bookDto = await _bookAppService.GetAsync(Id);
            Book = ObjectMapper.Map<BookDto, CreateUpdateBookDto>(bookDto);
        }

        public async Task<IActionResult> OnPostAsync()
        {
            await _bookAppService.UpdateAsync(Id, Book);
            return NoContent();
        }
    }
}

-2.3 由于添加了Dto CreateUpdateBookDto , 所以需要手动增加映射

using AutoMapper;

namespace Acme.BookStore.Web
{
    public class BookStoreWebAutoMapperProfile : Profile
    {
        public BookStoreWebAutoMapperProfile()
        {
            CreateMap<BookDto, CreateUpdateBookDto>();
        }
    }
}

• 2.4 修改客户端代码, 这里就是编辑的详情页面, 并且保存

@page
@using Acme.BookStore.Web.Pages.Books
@using Volo.Abp.AspNetCore.Mvc.UI.Bootstrap.TagHelpers.Modal
@model EditModalModel
@{
    Layout = null;
}
<abp-dynamic-form abp-model="Book" data-ajaxForm="true" asp-page="/Books/EditModal">
    <abp-modal>
        <abp-modal-header title="@L["Update"].Value"></abp-modal-header>
        <abp-modal-body>
            <abp-input asp-for="Id" />
            <abp-form-content />
        </abp-modal-body>
        <abp-modal-footer buttons="@(AbpModalButtons.Cancel|AbpModalButtons.Save)"></abp-modal-footer>
    </abp-modal>
</abp-dynamic-form>

3 为表格添加 "操作（Actions）" 下拉菜单

• 3.1 打开 Pages/Books/Index.cshtml 页面,并按下方所示修改表格部分的代码:

<abp-table striped-rows="true" id="BooksTable">
    <thead>
        <tr>
            <th>@L["Actions"]</th>
            <th>@L["Name"]</th>
            <th>@L["Type"]</th>
            <th>@L["PublishDate"]</th>
            <th>@L["Price"]</th>
            <th>@L["CreationTime"]</th>
        </tr>
    </thead>
</abp-table>

• 3.2 替换 js 内容, 增加相应的编辑功能

$(function () {

    var l = abp.localization.getResource('BookStore');

    var createModal = new abp.ModalManager(abp.appPath + 'Books/CreateModal');
    var editModal = new abp.ModalManager(abp.appPath + 'Books/EditModal');

    var dataTable = $('#BooksTable').DataTable(abp.libs.datatables.normalizeConfiguration({
        processing: true,
        serverSide: true,
        paging: true,
        searching: false,
        autoWidth: false,
        scrollCollapse: true,
        order: [[1, "asc"]],
        ajax: abp.libs.datatables.createAjax(acme.bookStore.book.getList),
        columnDefs: [
            {
                rowAction: {
                    items:
                        [
                            {
                                text: l('Edit'),
                                action: function (data) {
                                    editModal.open({ id: data.record.id });
                                }
                            }
                        ]
                }
            },
            { data: "name" },
            { data: "type" },
            { data: "publishDate" },
            { data: "price" },
            { data: "creationTime" }
        ]
    }));

    createModal.onResult(function () {
        dataTable.ajax.reload();
    });

    editModal.onResult(function () {
        dataTable.ajax.reload();
    });

    $('#NewBookButton').click(function (e) {
        e.preventDefault();
        createModal.open();
    });
});

4 删除书籍,打开 Pages/book/index.js 文件,在 rowAction items 下新增一项:

{
    text: l('Delete'),
    confirmMessage: function (data) {
        return l('BookDeletionConfirmationMessage', data.record.name);
    },
    action: function (data) {
        acme.bookStore.book
            .delete(data.record.id)
            .then(function() {
                abp.notify.info(l('SuccessfullyDeleted'));
                dataTable.ajax.reload();
            });
    }
}
