构建ASP.NET MVC4+EF5+EasyUI+Unity2.x注入的后台管理系统（45）-工作流设计-设计步骤
Controller
View Code
步骤设计很重要，特别是规则的选择。
我这里分为几个规则
1.按自行选择（在起草时候自行选审批人,比较灵活）
2.按上级（无需指定，当时需要知道用户的上司是谁，可以在职位管理设置，或者在用户表直接设置）
3.按职位（选择职位，直接获得该职位的人员）
4.按部门（按部门，直接获得该部分的人员）
5.按人员（设置步骤时就指定人员）
以上用户必须和部门，职位，上级有所关联，只要做好一个其实全部都同理
表结构分析：Flow_FormStep中有IsAllCheck字段我设计这个的目的是批量审核，比如我选择了部门，那么这个步骤要全部门的人都审核通过才算通过否则其中一人审核即可
先创建一个新的表单，必须有新的表单才能设置步骤
OK，新建好表单的字段之后，就可以设置步骤了
步骤设置很简单，就是一个从表关系，对应了表单的ID。从表可以直接简单看出关系，但设计其实比较有复杂，当选择组织架构，按职位，按指定人。都必须弹出窗口来进行选择，所以还要设计多3个弹出窗口，我这里只设计按人员筛选为例，因为按人员之前在权限管理的角色组管理已经实现
我这里“又”设计成了一个手风琴，具体实现如下
新建步骤和修改步骤=设计步骤
核心Action
[SupportFilter(ActionName = "Edit")] public ActionResult EditStep(string id) { ViewBag.Perm = GetPermission(); Flow_FormModel flowFormModel = m_BLL.GetById(id); List<Flow_StepModel> stepList = stepBLL.GetList(ref setNoPagerDescBySort, flowFormModel.Id);//获得全部步骤 foreach (var r in stepList)//获取步骤下面的步骤规则 { r.stepRuleList = GetStepRuleListByStepId(r.Id); } flowFormModel.stepList = stepList;//获取表单关联的步骤 ViewBag.Form = flowFormModel; Flow_StepModel model = new Flow_StepModel(); model.FormId = flowFormModel.Id; model.IsEditAttr = true; return View(model); } [HttpPost] [SupportFilter(ActionName = "Edit")] public JsonResult EditStep(Flow_StepModel model) { model.Id = ResultHelper.NewId; if (model != null && ModelState.IsValid) { if (stepBLL.Create(ref errors, model)) { LogHandler.WriteServiceLog(GetUserId(), "Id" + model.Id + ",Name" + model.Name, "成功", "创建", "Flow_Step"); return Json(JsonHandler.CreateMessage(1, Suggestion.InsertSucceed, model.Id)); } else { string ErrorCol = errors.Error; LogHandler.WriteServiceLog(GetUserId(), "Id" + model.Id + ",Name" + model.Name + "," + ErrorCol, "失败", "创建", "Flow_Step"); return Json(JsonHandler.CreateMessage(0, Suggestion.InsertFail + ErrorCol)); } } else { return Json(JsonHandler.CreateMessage(0, Suggestion.InsertFail)); } }

代码分析，控制器中的删除，修改，直接复制代码生成器生成的即可。
ActionResult EditStep，返回Flow_Step模型的同时也返回了Flow_Form的模型。
我修改了Flow_FormModel，让他支持自己的从表关系，必须添加以下2段即可
public List<Flow_FormAttrModel> attrList { get; set; }
public List<Flow_StepModel> stepList { get; set; }
注：本节一点悬念和技术点都没有，就是一个主表和从表的关系，只不过我是换了另一种方式来显示罢了
