介绍

ASP.NET MVC 5 SmartCode Scaffolding是集成在Visual Studio.Net开发工具中一个ASP.NET MVC Web应用程序代码生成框架，使用SmartCode Scaffolding可以快速添加一整套View,Controller,Model,Service可以运行的交互式代码。减少程序员在系统开发过程中编写重复的代码行数（估计可以减少80%代码Coding）,同时有助于团队成员遵循统一的架构和规范进行开发，就算没有接触过MVC的程序员也能快速的进行团队开发。大大减少对基础功能的debug的时间，提高软件项目的开发效率。

SmartCode Scaffolding是自定义扩展Visual Studio.Net ASP.NET Scaffolding并且实现了更多功能和生成更多的标准代码。非常适合快速原型法的开发过程。

该项目从2014年一直默默的在做版本更新和持续完善,从最早Visual Sutdio.Net 2013到最新2017。并且完全开源 GITHUB SmartCode Scaffolding

安装&使用

需要要配合Demo中WebApp 项目来生成代码，因为其中引用了大量的css和html模板

代码生成的过程

定义实体对象(Entity class)和属性

参考EntityFramewrok Code-First规范定义，定义的越规范，信息越多对后面的生成的代码就越完善。

下面代码定义一个Order，OrderDetail,一对多的关系，在创建Order类的Controller时会在controller，View，会根据关联的实体生成相应的代码，

比如EditView，会同时生成对表头Order form表单的操作和明细表OrderDetail的datagrid操作。
定义OrderDetail中引用了Product，多对一的关系。会在View部分生成Combox控件或DropdownList的控件和Controller层的查询方法。

//定义字段描述信息，字段长度，基本验证规则 public partial class Order:Entity { public Order() { OrderDetails = new HashSet(); } [Key] public int Id { get; set; } [Required] [Display(Name ="客户名称",Description ="订单所属的客户",Order =1)] [MaxLength(30)] public string Customer { get; set; } [Required] [Display(Name = "发货地址", Description = "发货地址", Order = 2)] [MaxLength(200)] public string ShippingAddress { get; set; } [Display(Name = "订单日期", Description = "订单日期默认当天", Order = 3)] public DateTime OrderDate { get; set; } //关联订单明细 1-* public virtual ICollection OrderDetails { get; set; } } public partial class OrderDetail:Entity { [Key] public int Id { get; set; } [Required(ErrorMessage = "必选")] [Display(Name ="商品", Description ="商品",Order =2)] public int ProductId { get; set; } [ForeignKey("ProductId")] [Display(Name = "商品", Description = "商品", Order = 3)] public Product Product { get; set; } [Required(ErrorMessage="必填")] [Range(1,9999)] [Display(Name = "数量", Description = "需求数量", Order = 4)] public int Qty { get; set; } [Required(ErrorMessage = "必填")] [Range(1, 9999)] [Display(Name = "单价", Description = "单价", Order = 5)] public decimal Price { get; set; } [Required(ErrorMessage = "必填")] [Range(1, 9999)] [Display(Name = "金额", Description = "金额(数量x单价)", Order = 6)] public decimal Amount { get; set; } [Display(Name = "订单号", Description = "订单号", Order = 1)] public int OrderId { get; set; } //关联订单表头 [ForeignKey("OrderId")] [Display(Name = "订单号", Description = "订单号", Order = 1)] public Order Order { get; set; } }

生成代码

添加controller

生成以下代码

Controllers\OrdersController.cs /* MVC控制类 */Repositories\Orders\OrderQuery.cs /* 定义与业务逻辑相关查询比如分页帅选，外键/主键查询 */Repositories\Orders\OrderRepository.cs /* Repository模式 */Services\Orders\IOrderService.cs /* 具体的业务逻辑接口 */Services\Orders\OrderService.cs /* 具体的业务逻辑实现 */Views\Orders\Index.cshtml /* 订单信息DataGrid包括查询/新增/删除/修改/导入/导出等功能 */Views\Orders\_PopupDetailFormView.cshtml /* 订单信息弹出编辑框 */Views\Orders\Create.cshtml /* 订单信息新增操作页面 */Views\Orders\Edit.cshtml /* 订单信息编辑操作页面 */Views\Orders\EditForm.cshtml /* 订单信息编辑表单 */
