• IDE为VS 2019,dotnetcore版本为3.1

创建项目


  • 打开VS,依次点击工具栏文件按钮->新建->项目,搜索框输入`ASP.Net Core`,语言选择`C#`,在筛选结果中选择`ASP.Net Core Web 应用程序`,点击下一步。

  • 填写项目名称,再下一步,选择`3.1`版本,模板选择`Web 应用程序`,最后点击创建。

  • 创建完之后,项目结构如下。

安装并应用NewLife.Cube.Core


  • 右键点击项目中依赖项->点击管理NuGet程序包->搜索框输入`NewLife.Cube.Core`,选中搜索结果,点击安装。image.png
  • Startup.cs文件修改如下。
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using NewLife.Cube;

namespace CubeDemo
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews(); // 2020-12-26添加
            services.AddCube();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseCube();
        }
    }
}
  • 按F5运行项目,一切顺利的话,就能看到魔方的登录页面,默认账号密码都是`admin`,登录进去,可看到内置的控制器。注意:初始化运行需要下载静态资源和驱动,生成菜单,所以出现异常或者页面样式不对,都是正常现象,稍等或重新运行项目即可。
  • 有时候文档来不及更新,可以参考代码中的例子Startup.cs

添加自己的页面

新建区域

  • 首先新建区域School,手动创建文件夹Areas/School,在此文件夹创建区域类SchoolArea,填入以下内容。
using System;
using System.ComponentModel;
using NewLife.Cube;

namespace CubeDemo.Areas.School
{
    [DisplayName("教务系统")]
    public class SchoolArea : AreaBase
    {
        public SchoolArea() : base(nameof(SchoolArea).TrimEnd("Area")) { }

        static SchoolArea() => RegisterArea<SchoolArea>();
    }
}

新建实体

新建控制器

  • 新建文件夹Areas/School/Controllers,新建ClassController、StudentController两个控制器,分别填入以下内容。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Reflection;
using Microsoft.AspNetCore.Mvc;
using NewLife.Cube;
using NewLife.School.Entity;
using NewLife.Web;
using XCode.Membership;

namespace CubeDemo.Areas.School.Controllers
{
    [SchoolArea]
    [DisplayName("班级")]
    public class ClassController : EntityController<Class>
    {
        protected override IDictionary<MethodInfo, Int32> ScanActionMenu(IMenu menu)
        {
            menu.Visible = true;
            return base.ScanActionMenu(menu);
        }
    }
}
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Reflection;
using Microsoft.AspNetCore.Mvc;
using NewLife.Cube;
using NewLife.School.Entity;
using NewLife.Web;
using XCode.Membership;

namespace CubeDemo.Areas.School.Controllers
{
    [SchoolArea]
    [DisplayName("学生")]
    public class StudentController : EntityController<Student>
    {
        static StudentController()
        {
            ListFields.RemoveField("CreateUserID");
            ListFields.RemoveField("UpdateUserID");
            //FormFields
        }

        protected override IDictionary<MethodInfo, Int32> ScanActionMenu(IMenu menu)
        {
            menu.Visible = true;
            return base.ScanActionMenu(menu);
        }
    }
}

页面修改

  • 此时运行,一切正常,可看到如下页面。

  • 如果要修改页面,那么直接在对应位置建立对应视图文件即可自动覆盖。详细可覆盖文件参考这里
  • 比如修改学生主页,则新建文件Areas/School/Views/Student/,新建文件_List_Data.cshtml。填入以下内容。
@using NewLife;
@using NewLife.Cube
@using NewLife.Web;
@using XCode;
@using XCode.Configuration;
@using XCode.Membership
@{
    var fact = ViewBag.Factory as IEntityFactory;
    var page = ViewBag.Page as Pager;
    var fields = ViewBag.Fields as List<FieldItem>;
}
<table class="table table-bordered table-hover table-striped table-condensed">
    <thead>
        <tr>
            <th class="text-center hidden-md hidden-sm hidden-xs"><a href="@Html.Raw(page.GetSortUrl("ID"))">编号</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("ClassID"))">班级2</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Name"))">名称3</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Sex"))">性别4</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Age"))">年龄5</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Mobile"))">手机</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Address"))">地址</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("CreateTime"))">创建时间</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("CreateIP"))">创建地址</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("UpdateTime"))">更新时间</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("UpdateIP"))">更新地址</a></th>
            <th class="text-center"><a href="@Html.Raw(page.GetSortUrl("Remark"))">备注</a></th>
            @if (this.Has(PermissionFlags.Detail, PermissionFlags.Update, PermissionFlags.Delete))
            {
                <th class="text-center">操作</th>
            }
        </tr>
    </thead>
    <tbody>
        @foreach (var entity in Model)
        {
            <tr>
                <td class="text-center hidden-md hidden-sm hidden-xs">@entity.ID</td>
                <td>@entity.ClassName</td>
                <td>@entity.Name</td>
                <td class="text-center">@entity.Sex</td>
                <td class="text-right">@entity.Age.ToString("n0")</td>
                <td>@entity.Mobile</td>
                <td>@entity.Address</td>
                <td>@Utility.ToFullString(entity.CreateTime, "")</td>
                <td>@entity.CreateIP</td>
                <td>@Utility.ToFullString(entity.UpdateTime, "")</td>
                <td>@entity.UpdateIP</td>
                <td>@entity.Remark</td>
                @if (this.Has(PermissionFlags.Detail, PermissionFlags.Update, PermissionFlags.Delete))
                {
                    <td class="text-center">
                        @await Html.PartialAsync("_List_Data_Action", (Object)entity)
                    </td>
                }
            </tr>
        }
    </tbody>
</table>
  • 修改后页面如下。其他页面均可按照此方式进行覆盖。
