业务模型概述

业务模型管理中所涉及的业务模型，业务模型的属性，业务模型的视图都是可以通过权限设置来实现数据的行（视图），列（属性）权限管控。业务模型是整个EDP平台的核心基础，数据的查询、新增、修改、删除、行列权限都是通过业务模型来实现的。

业务模型管理

按分类管理系统内各个业务模型，对应系统中各个业务对象。

业务模型分类

管理业务模型分类。

业务模型

• 新增业务模型
  
  
  
  

• 编辑业务模型
  
  
  
  
  
  

• 业务模型代码生成
  
  
  
  

  表设计文档模板，可以包含多个表结构设计
  
  

业务模型开发

定义业务模型

创建业务模型类，继承基类ModelPermissionBase。定义好的业务模型可以在上述的业务模型管理功能中进行管理，实现数据行、列权限的管控。

TableName：表名

KeyName：主键对应的属性名

ColumnName：字段名称

IsRequired：是否必须，用于验证属性值是否必须有值

MaxLength：最大长度，属性值的最大长度

[ModelEnitity(ColumnName = "ContactMobile", Regex = @"^[1]([3-9])[0-9]{9}$")]

Regex：正则表达式，用于验证属性值格式

            //引入命名空间 using EDP.Common;
            //default:注册表配置中数据库连接配置所对应的"Key"值
            //若没有设置连线字串,则取注册表配置中的默认数据库连接
            //this.SetConnectionString(Config.Database["default"]); 示例项目使用默认数据库连接,不需要设置
        }

在构造函数中通过SetDefaultQuerySQL()方法设置默认查询SQL，通过SetConnectionString()方法设置数据库连接字符串（若没设置则取默认数据库连接字串）。

public string CampusName { get; set; }

扩展属性是默认查询SQL中所查询的非业务模型映射的表中的字段。

public void Modify(string keyValue, IDBInstance db = null) {
    this.ID = keyValue;
    this.Modify(db);
}

在业务对象上提供Create()和Modify()扩展方法，用于在创建和修改业务时调用，给业务对象必要属性赋值。

定义查询对象

查询对象是用来实现业务对象的查询，通过属性来设置查询条件。需要继承QueryModelBase基类。

点击查看代码

using System;

namespace School.Model
{
    using EDP.Common;
    using EDP.Common.Model;

    /// <summary>
    /// 学生信息查询对象
    /// </summary>
    [QueryModel] //标记类的查询对象特性
    public class StudentQueryModel : QueryModelBase //继承QueryModelBase
    {
        /// <summary>
        /// 姓名
        /// </summary>
        [QueryModel(Operator = QueryOperator.like, ColumnName = "Name")]
        public string Name { get; set; }

        /// <summary>
        /// 性别
        /// </summary>
        [QueryModel(Operator = QueryOperator.eq, ColumnName = "GenderId")]
        public int? GenderId { get; set; }

        /// <summary>
        /// 校区
        /// </summary>
        [QueryModel(Operator = QueryOperator.eq, ColumnName = "CampusId")]
        public string CampusId { get; set; }

        /// <summary>
        /// 班级
        /// </summary>
        [QueryModel(Operator = QueryOperator.eq, ColumnName = "ClassId")]
        public string ClassId { get; set; }

        /// <summary>
        /// 班级全编码
        /// </summary>
        /// <example>ClassFullCode like '值%'</example>
        [QueryModel(Operator = QueryOperator.likeRight, ColumnName = "ClassFullCode")]
        public string ClassFullCode { get; set; }

        /// <summary>
        /// 编号姓名关键字
        /// Number和Name都进行like查询
        /// </summary>
        /// <example>Number like '%关键字%' or Name like '%值%'</example>
        [QueryModel(Operator = QueryOperator.like, ColumnNameList = "Number;Name")]
        public string NumberNameKeywrod { get; set; }

        /// <summary>
        /// 分页对象
        /// </summary>
        public PageModel Page { get; set; } = new PageModel();
    }
}

[QueryModel(Operator = QueryOperator.like, ColumnName = "Name")]

Operator：查询操作符（=、>、<、>=、like等）

ColumnName：对应业务对象的属性（实体属性，扩展属性），只要是默认查询SQL中包含的字段都可以作为查询对象的属性（查询条件）

业务模型使用

详见示例项目StudentBLL.cs

• 业务模型属性验证
  
  var verify = item.Verify(keyValue);
  
  此处通过Verify()方法验证业务模型各属性值，通过属性验证标记（IsRequired，MaxLength, Regex）进行验证。

• 业务模型新增

点击查看代码

item.Create(db);
item.ValidateSQL = string.Format("where not exists (select 1 from t_school_student where Number = '{0}')", item.Number);
result = item.InsertModel(db);

通过业务模型Create()方法创建当前实体对象。
通过ValidateSQL属性值确保不会有重复的Number值插入到数据库。
调用InsertModel()方法新增业务模型数据。

• 修改业务模型

点击查看代码

item.Modify(keyValue, db);
item.Number = null; //编号不能修改
result = item.UpdateModel(db);

通过业务模型Modify()方法修改当前实体对象。
调用UpdateModel()方法修改业务模型数据。

• 业务模型查询

点击查看代码

ResultModel<StudentModel> ret = new ResultModel<StudentModel>();
ret.Content = new StudentModel();
ret.KeyValue = keyValue;
ret.Content.ID = keyValue;
ret.Content.Query(db);

使用统一的返回对象 ResultModel<StudentModel>。
实例化ret.Content并设置操作的主键值ret.KeyValue = keyValue。
设置查询的主键值 ret.Content.ID = keyValue。
调用业务对象Query()方法 ret.Content.Query(db)。
执行Query()查询后，根据权限设置给ret.Content赋值。
ret.Content.AccessPropertyList中返回有权限的属性名称。

• 业务模型列表查询

点击查看代码

ResultModel<List<StudentModel>> ret = new ResultModel<List<StudentModel>>();
ret.Content = new List<StudentModel>();
ret.Content.Query(queryModel.Page, queryModel, db);
ret.Page = queryModel.Page;

使用统一的返回对象 ResultModel<List<StudentModel>>。
实例化 ret.Content = new List<StudentModel>()。
调用业务对象Query()方法 ret.Content.Query(queryModel.Page, queryModel, db)。
queryModel为查询对象StudentQueryModel的实例。
执行Query()查询后，根据权限设置给ret.Content赋值（有权限的数据集合）。
ret.Content[0].AccessPropertyList中返回有权限的属性名称。

• 业务模型删除

点击查看代码

StudentModel item = new StudentModel();
item.Id = keyValue;
item.DeleteModel();

实例化StudentModel。
设置主键值 item.Id = keyValue。
调用业务对象DeleteModel()方法 item.DeleteModel()。
