MVC 5 Scaffolder + EntityFramework+UnitOfWork Pattern 代码生成工具集成Visual Studio 2013
MVC 5 Scaffolder + EntityFramework+UnitOfWork Pattern 代码生成工具
经过一个多星期的努力总算完成了单表,多表关联(一对多,多对一)的增删改查的代码生成,基本上可以实现不用添加任何代码完成对数据表的操作。
下个阶段打算集成.net 4.5的认证和授权已经用户注册和角色管理
一旦有更好的方式我会把它集成到模板中实现自动生成。所以很希望得到大家的帮助。在这里我先抛砖引玉了。
asp.net MVC 5 Scaffolding多层架构代码生成向导开源项目(邀请你的参与)
Demo和所有源代码代码在 https://github.com/neozhu/MVC5-Scaffolder
先看一下我的Demo实例
实体类的结构
Order 与 OrderDetail 一对多,OrderDetail 与 Product 多对一,Order与Product则是多对多的关系。
实现的操作界面如下图
查询界面
功能:
1/新增操作 : 页面跳转到新增页面
2/删除操作 : 选择记录或单击行上的删除 弹出确认框 是否删除改记录
3/编辑操作 : 单击行上的编辑图标页面跳转到编辑页面
4/查询操作 : 在Search 文本框中输入关键字会根据后台每个字段的查询,选择需要显示的字段
5/Table功能 :字段显示勾选,分页显示,所有功能都是服务端实现
新增页面
功能:
布局:上部表头,下部的Tab为表体明细
一对多 :表体用table显示
多对一 :用Dropdownlist进行选择
表体明细的操作 :使用popup modal的方式操作
单击保存后,系统会自动合并表头表体一起提交到后台进行保存
编辑页面
功能:
加载数据:会根据主从关系把表头/表体的数据一次性加载
编辑数据:对表体明细的的操作类似新增页面,但对表体进行删除操作时会进行提示是否真的要删除后台数据。
保存数据:一次性提交所有表头/表体数据到后台进行操作。
上述这些功能完全可以代码生成 不需要做任何修改
项目结构
View层的代码
Index :查询Table List
Create :新增页面
Edit : 编辑页面
EditForm :Partial View内嵌在Create 和Edit页面中
_OrderDetailForm : pupup 子表维护表单页面
Create,和Edit页面通过Ajax Post 把数据提交到后台的Controller进行操作
代码如下
<script type="text/javascript"> var orderid = 0; var ObjectState = "Added"; var $orderdetailstable = {}; $(document).ready(function () { $('form').submit(function () { var token = $('[name=__RequestVerificationToken]').val(); var serializedForm = $(this).serialize(); var actionurl = $(this).attr('action'); var orderdetails = $orderdetailstable.bootstrapTable('getData'); var newitem = { OrderDetails: orderdetails, Id: orderid, Customer: $('#Customer', 'form').val(), ShippingAddress: $('#ShippingAddress', 'form').val(), OrderDate: $('#OrderDate', 'form').val(), ObjectState: ObjectState }; $.ajax({ url: actionurl, type: "POST", dataType: "json", contentType: "application/json; charset=utf-8", data: JSON.stringify(newitem), success: function (result) { if (result.success) { self.location = "/Orders/Index"; } else { alert(result.err); } }, error: function (result) { console.log(result.statusText + result.responseText); alert(result.statusText + result.responseText); } }); return false; }); }); </script>
通过Jquery 获取表头和表体数据 序列化成Json对象然后Post到后台
Controller层代码
这里就只贴Create方法的代码
public class OrdersController : Controller { //private StoreContext db = new StoreContext(); private readonly IOrderService _orderService; private readonly IUnitOfWorkAsync _unitOfWork; public OrdersController(IOrderService orderService, IUnitOfWorkAsync unitOfWork) { _orderService = orderService; _unitOfWork = unitOfWork; } // GET: Orders/Index public ActionResult Index() { var orders = _orderService.Queryable().AsQueryable(); return View(orders); } // Get :Orders/PageList // For Index View Boostrap-Table load data [HttpGet] public ActionResult PageList(int offset = 0, int limit = 10, string search = "", string sort = "", string order = "") { int totalCount = 0; int pagenum = offset / limit + 1; var orders = _orderService.Query(new OrderQuery().WithAnySearch(search)).OrderBy(n => n.OrderBy(sort, order)).SelectPage(pagenum, limit, out totalCount); var rows = orders.Select(n => new { Id = n.Id, Customer = n.Customer, ShippingAddress = n.ShippingAddress, OrderDate = n.OrderDate }).ToList(); var pagelist = new { total = totalCount, rows = rows }; return Json(pagelist, JsonRequestBehavior.AllowGet); } // GET: Orders/Details/5 public ActionResult Details(int? id) { if (id == null) { return new HttpStatusCodeResult(HttpStatusCode.BadRequest); } Order order = _orderService.Find(id); if (order == null) { return HttpNotFound(); } return View(order); } // GET: Orders/Create public ActionResult Create() { return View(); } // POST: Orders/Create // To protect from overposting attacks, please enable the specific properties you want to bind to, for more details see http://go.microsoft.com/fwlink/?LinkId=317598.

所有代码都是根据Entity 类型 和字段名进行生成,理论上针对业务系统都可以模板化,只要模式定下来什么代码都可以生成。
