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。

[ModelEnitity(TableName = "t_school_student", KeyName = "ID")]
TableName:表名
KeyName:主键对应的属性名
[ModelEnitity(ColumnName = "Name", IsRequired = true, MaxLength = 50)]
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
点击查看代码- /// <summary>

复制代码 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。

- this.Modify(db);
- }
复制代码 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();
- }
- }
复制代码 [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);
复制代码- 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。
复制代码 点击查看代码- item.Modify(keyValue, db);
- item.Number = null; //编号不能修改
- result = item.UpdateModel(db);
复制代码- 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。
复制代码 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);
复制代码- 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。
复制代码 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;
复制代码- 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。
复制代码 点击查看代码- StudentModel item = new StudentModel();
- item.Id = keyValue;
- item.DeleteModel();
复制代码- 实例化StudentModel。
- 设置主键值 item.Id = keyValue。
- 调用业务对象DeleteModel()方法 item.DeleteModel()。
