Winform开发框架之单据窗体生成(主从表，流水单号)

标签：

源码地址：https://github.com/GarsonZhang/GZFramework.ShareDemo

前言

1.在开始本节前请先重置代码为 chapter-03-start

懒人地址：https://github.com/GarsonZhang/GZFramework.ShareDemo/tree/chapter-03-start

2.创建表(商品入库主表/明细)

创建脚本目录：数据库脚本/Chapter-03新建商品入库表(主从表).sql

3.新建生成单据流水号所需的表和存储过程

创建脚本目录：数据库脚本/Chapter-03新建商品入库表(主从表).sql

生成器生成界面

1.修改相关底层生成规则

修改文件：_GZFramework.Demo.Business.Base.dalBase.cs

修改流水单号生成函数：GetDataSN，调用创建的存储过程创建流水单号

      //获取流水单号
        public override string GetDataSN(IDatabase db, string sDocCode, int sLength)
        {
            return sDocCode + db.ExecuteScalarSP<string>("sys_GetDataSN",
                new { DataCode = sDocCode, Length = sLength });
        }

View Code

修改下服务器时间获取函数:GetServerTime(不同数据库类型获取方式不一样)

      //获取系统时间，建议从服务器获取
        public override DateTime GetServerTime(IDatabase db)
        {
            string sql = "SELECT GETDATE()";
            return db.ExecuteScalar<DateTime>(sql);
        }

View Code

2.使用生成器生成界面

1.先生成入库主表和明细表的Model

添加新项，选择 Model层生成

配置相关生成信息，并生成静态结构

 

生成的Model类如下,其中包含两个静态结构类，一个是主表tb_GoodsIn,一个是明细表tb_GoodsInDetail：

2.生成界面：

配置主表生成信息：

配置明细表生成信息：注意先添加明细表

 

生成以后的窗体如下：

3.修改Management如下（红色背景为新增的行）

       public Management()
        {
            FunctionCollection.AddFunction(typeof(frmMyUser), "用户管理", "Function_Account");
           

FunctionCollection.AddFunction(typeof(frmGoodsIn), "商品入库", "");

        }

View Code

运行软件，如下图所示：

商品入库出现，图片可以在Management.cs中第三个参数设置，注意图片尺寸是64x64,放在images目录下，后缀应该是 _64x64,比如用户管理第三个参数为Function_Accouint,其在images下的图片全名应该为：Function_Accouint_64x64.png

获取图片的相应方法在_GZFramework.Demo.Library.MyClass.LoadUIImage类中

功能使用如下图，(保存验证不通过状态,即必填项为空)

当一个单据新建成功后会自动生成一个流水单号：

其中前缀和位数，都是我们在生成界面中指定的
