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

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。
