这篇将继续围绕上篇所说的第二种方法，记录说明一下自己遇到的问题以及解决方法。

一、创建或更新包含子表的表单

二、流程事件变化后执行某些逻辑

 

一、创建或更新包含子表的表单

1、首先介绍关于在后端创建包含子表的表单：

 

 1 //根据ID查询当前表单数据
 2 string sql1 = "select Warehouse1 as Warehouse1,MyProject as MyProject,Class1 as Class1,People as People,Dept as Dept," +
 3     "Principal as Principal from I_D000399SgProductionAcquisition where Objectid = ‘" + ObjectId + "‘";
 4 System.Data.DataTable table1 = this.Engine.Query.QueryTable(sql1, null);
 5 int rowCount1 = table1.Rows.Count;
 6 
 7 //根据ID查询当前表单子表数据
 8 string sql2 = "select ControlCatalogue as ControlCatalogue,No as No,MaterialName as MaterialName,Type as Type,Unit1 as Unit1 " +
 9     "from I_D000399SgBugApplyDetails where parentobjectid = ‘" + ObjectId + "‘";
10 System.Data.DataTable table2 = this.Engine.Query.QueryTable(sql2, null);
11 int rowCount2 = table2.Rows.Count;
12 
13 List < H3.DataModel.BizObject > _list = new List<H3.DataModel.BizObject>();
14 for(int i = 0;i < rowCount2; i++) {
15     //创建子表对象
16     H3.DataModel.BizObject childBo = new H3.DataModel.BizObject(this.Request.Engine, this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SqOutbound01"), this.Request.UserContext.UserId);
17     childBo["ControlCatalogue"] = table2.Rows[i]["ControlCatalogue"].ToString();
18     childBo["No"] = table2.Rows[i]["No"].ToString();
19     childBo["MaterialName"] = table2.Rows[i]["MaterialName"].ToString();
20     childBo["Type"] = table2.Rows[i]["Type"].ToString();
21     childBo["Unit1"] = table2.Rows[i]["Unit1"].ToString();
22     childBo.Create();
23     _list.Add(childBo);
24 }
25 
26 //创建主表对象
27 H3.DataModel.BizObject bo = new H3.DataModel.BizObject(this.Engine, this.Engine.BizObjectManager.GetPublishedSchema("D000399SqOutbound"), this.Request.UserContext.UserId);
28 bo["WDate"] = DateTime.Today.ToString("yyyy-MM-dd");
29 bo["YearMonth"] = DateTime.Today.ToString("yyyyMM");
30 bo["Title"] = "审核批量，生产领用出库";
31 bo["Acquisition"] = ObjectId;
32 bo["No"] = No;
33 bo["Money"] = AllMoney;
34 for(int i = 0;i < rowCount1; i++) {
35     bo["Warehouse1"] = table1.Rows[i]["Warehouse1"].ToString();
36     bo["MyProject"] = table1.Rows[i]["MyProject"].ToString();
37     bo["Class"] = table1.Rows[i]["Class1"].ToString();
38     bo["People"] = table1.Rows[i]["People"].ToString();
39     bo["Dept"] = table1.Rows[i]["Dept"].ToString();
40     bo["Principal"] = table1.Rows[i]["Principal"].ToString();
41 }
42 bo["D000399SqOutbound01"] = _list.ToArray();
43 bo.Status = H3.DataModel.BizObjectStatus.Effective;
44 bo.Create();

 

上述代码是根据ID，查询某表单以及其子表数据，再将数据对应赋值给创建的表单以及创建表单的子表，这里表单或者其子表的ID都是系统自己随机生成，同时可以设置创建表单的状态，需要注意的是这里创建后的表单继续会触发它对应的业务规则。

 

2、再介绍关于在后端更新包含子表的表单：

 1 //查询当前表单子表中需要冲减的数量
 2 string sql1 = "select ControlCatalogue as ControlCatalogue,Num3 as Num3 from I_D000399SgBuyDetails" +
 3     " where parentobjectId = ‘" + BuyApply + "‘ and Num3 != 0";
 4 System.Data.DataTable table1 = this.Engine.Query.QueryTable(sql2, null);
 5 int rowCount1 = table1.Rows.Count; 
 6 
 7 H3.Data.Filter.Filter filter = new H3.Data.Filter.Filter();
 8 H3.Data.Filter.And andMatcher = new H3.Data.Filter.And();
 9 
10 andMatcher.Add(new H3.Data.Filter.ItemMatcher("ObjectId", H3.Data.ComparisonOperatorType.Equal, UseAllPlan));
11 filter.Matcher = andMatcher;
12 H3.DataModel.BizObjectSchema accountSchema = this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SgUseAllPlan");
13 H3.DataModel.BizObject[] customers = H3.DataModel.BizObject.GetList(this.Request.Engine, this.Request.UserContext.UserId,
14     accountSchema, H3.DataModel.GetListScopeType.GlobalAll, filter);
15 if(customers != null && customers.Length > 0)
16 {
17     H3.DataModel.BizObject[]  details = (H3.DataModel.BizObject[]) customers[0]["D000399SgUseAllDetails"];
18     List < H3.DataModel.BizObject > boList = new List<H3.DataModel.BizObject>();
19     //保存原子表记录，先获取子表内容，循环将其原有数据添加到boList
20     if(details != null)
21     {
22         foreach(H3.DataModel.BizObject dt in details)
23         {
24             for(int i = 0;i < rowCount1; i++) {
25                 string ControlCatalogue = table1.Rows[i]["ControlCatalogue"].ToString();
26                 string Num3 = table1.Rows[i]["Num3"].ToString();
27 
28                 if(string.Equals(dt["ControlCatalogue"], ControlCatalogue))
29                 {
30                     int temp1 = Convert.ToInt32(dt["Num4"]) - Convert.ToInt32(Num3);
31                     dt["Num4"] = Convert.ToString(temp1);
32                     int temp2 = Convert.ToInt32(dt["Num5"]) + Convert.ToInt32(Num3);
33                     dt["Num5"] = Convert.ToString(temp2);
34                 }
35             }
36             boList.Add(dt);
37         }
38     }
39     H3.DataModel.BizObjectSchema schema = this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SgUseAllPlan");
40     H3.DataModel.BizObject schemaObject = new H3.DataModel.BizObject(this.Request.Engine, schema, this.Request.UserContext.UserId);
41     schemaObject.ObjectId = UseAllPlan;  //更新的表单ID为UseAllPlan
42     schemaObject.Load();
43     schemaObject["D000399SgUseAllDetails"] = boList.ToArray();
44     schemaObject.Update();
45 } 

上述代码是根据ID，更新目标表单的子表数据，需要注意的是这里更新后的表单同样会触发它对应的业务规则，如果不想触发业务规则，也可采用sql语句更新的方式，如下所示。

1 //将‘项目信息‘中项目成员赋值给‘我的项目’的项目成员
2 string sql1 = "update I_D000399SgProjectMy set I_D000399SgProjectMy.Members = (select Members from I_D000399SgProject "+
3                 "where I_D000399SgProjectMy.Project = I_D000399SgProject.Objectid)";
4 this.Engine.Query.QueryTable(sql1, null);

 

二、流程事件变化后执行某些逻辑

当一个表单生效或作废后，若有业务规则首先会执行业务规则，通常有更新或新增等操作。然后再执行流程变化后事件。前提是当前表单已经开启了表单流程。代码如下：

 

 1 protected override void OnWorkflowInstanceStateChanged(H3.Workflow.Instance.WorkflowInstanceState oldState, H3.Workflow.Instance.WorkflowInstanceState newState)
 2     {
 3         //流程审批结束,业务规则执行。还有个审批流程结束（finished状态下直接删除），就直接删除也会触发业务规则执行。在submit里面处理
 4         if(oldState == H3.Workflow.Instance.WorkflowInstanceState.Running && newState == H3.Workflow.Instance.WorkflowInstanceState.Finished)
 5         {
 6             DoAfterPass1(this.Request.BizObject.ObjectId);
 7         }
 8         //流程审批结束后，重新激活，业务规则会执行。还有个审批流程结束（finished状态下直接删除），就直接删除也会触发业务规则执行。在submit里面处理
 9         if(oldState == H3.Workflow.Instance.WorkflowInstanceState.Finished && newState == H3.Workflow.Instance.WorkflowInstanceState.Running)
10         {
11             DoAfterPass2(this.Request.BizObject.ObjectId);
12         }
13         base.OnWorkflowInstanceStateChanged(oldState, newState);
14     }

 this.Request.BizObject.ObjectId; //当前表单的ID

至此是对氚云部分功能的一个简单介绍，后续会继续说明其它部分功能所遇到的问题以及解决方法。

如有疏漏错误之处，还请不吝赐教！
