MVC 5 Scaffolder + EntityFramework+UnitOfWork Pattern 代码生成工具

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
