基於氚雲平台的應用開發學習(三)

這篇將繼續圍繞上篇所說的第二種方法，記錄說明一下自己遇到的問題以及解決方法。

一、創建或更新包含子表的表單

二、流程事件變化后執行某些邏輯

三、發送消息提醒

 

一、創建或更新包含子表的表單

1、首先介紹關於在后端創建包含子表的表單：

 

//根據ID查詢當前表單數據
string sql1 = "select Warehouse1 as Warehouse1,MyProject as MyProject,Class1 as Class1,People as People,Dept as Dept," +
    "Principal as Principal from I_D000399SgProductionAcquisition where Objectid = '" + ObjectId + "'";
System.Data.DataTable table1 = this.Engine.Query.QueryTable(sql1, null);
int rowCount1 = table1.Rows.Count;

//根據ID查詢當前表單子表數據
string sql2 = "select ControlCatalogue as ControlCatalogue,No as No,MaterialName as MaterialName,Type as Type,Unit1 as Unit1 " +
    "from I_D000399SgBugApplyDetails where parentobjectid = '" + ObjectId + "'";
System.Data.DataTable table2 = this.Engine.Query.QueryTable(sql2, null);
int rowCount2 = table2.Rows.Count;

List < H3.DataModel.BizObject > _list = new List<H3.DataModel.BizObject>();
for(int i = 0;i < rowCount2; i++) {
    //創建子表對象
    H3.DataModel.BizObject childBo = new H3.DataModel.BizObject(this.Request.Engine, this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SqOutbound01"), this.Request.UserContext.UserId);
    childBo["ControlCatalogue"] = table2.Rows[i]["ControlCatalogue"].ToString();
    childBo["No"] = table2.Rows[i]["No"].ToString();
    childBo["MaterialName"] = table2.Rows[i]["MaterialName"].ToString();
    childBo["Type"] = table2.Rows[i]["Type"].ToString();
    childBo["Unit1"] = table2.Rows[i]["Unit1"].ToString();
    childBo.Create();
    _list.Add(childBo);
}

//創建主表對象
H3.DataModel.BizObject bo = new H3.DataModel.BizObject(this.Engine, this.Engine.BizObjectManager.GetPublishedSchema("D000399SqOutbound"), this.Request.UserContext.UserId);
bo["WDate"] = DateTime.Today.ToString("yyyy-MM-dd");
bo["YearMonth"] = DateTime.Today.ToString("yyyyMM");
bo["Title"] = "審核批量，生產領用出庫";
bo["Acquisition"] = ObjectId;
bo["No"] = No;
bo["Money"] = AllMoney;
for(int i = 0;i < rowCount1; i++) {
    bo["Warehouse1"] = table1.Rows[i]["Warehouse1"].ToString();
    bo["MyProject"] = table1.Rows[i]["MyProject"].ToString();
    bo["Class"] = table1.Rows[i]["Class1"].ToString();
    bo["People"] = table1.Rows[i]["People"].ToString();
    bo["Dept"] = table1.Rows[i]["Dept"].ToString();
    bo["Principal"] = table1.Rows[i]["Principal"].ToString();
}
bo["D000399SqOutbound01"] = _list.ToArray();
bo.Status = H3.DataModel.BizObjectStatus.Effective;
bo.Create();

 

上述代碼是根據ID，查詢某表單以及其子表數據，再將數據對應賦值給創建的表單以及創建表單的子表，這里表單或者其子表的ID都是系統自己隨機生成，同時可以設置創建表單的狀態，需要注意的是這里創建后的表單繼續會觸發它對應的業務規則。

 

2、再介紹關於在后端更新包含子表的表單：

//查詢當前表單子表中需要沖減的數量
string sql1 = "select ControlCatalogue as ControlCatalogue,Num3 as Num3 from I_D000399SgBuyDetails" +
    " where parentobjectId = '" + BuyApply + "' and Num3 != 0";
System.Data.DataTable table1 = this.Engine.Query.QueryTable(sql2, null);
int rowCount1 = table1.Rows.Count; 

H3.Data.Filter.Filter filter = new H3.Data.Filter.Filter();
H3.Data.Filter.And andMatcher = new H3.Data.Filter.And();

andMatcher.Add(new H3.Data.Filter.ItemMatcher("ObjectId", H3.Data.ComparisonOperatorType.Equal, UseAllPlan));
filter.Matcher = andMatcher;
H3.DataModel.BizObjectSchema accountSchema = this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SgUseAllPlan");
H3.DataModel.BizObject[] customers = H3.DataModel.BizObject.GetList(this.Request.Engine, this.Request.UserContext.UserId,
    accountSchema, H3.DataModel.GetListScopeType.GlobalAll, filter);
if(customers != null && customers.Length > 0)
{
    H3.DataModel.BizObject[]  details = (H3.DataModel.BizObject[]) customers[0]["D000399SgUseAllDetails"];
    List < H3.DataModel.BizObject > boList = new List<H3.DataModel.BizObject>();
    //保存原子表記錄，先獲取子表內容，循環將其原有數據添加到boList
    if(details != null)
    {
        foreach(H3.DataModel.BizObject dt in details)
        {
            for(int i = 0;i < rowCount1; i++) {
                string ControlCatalogue = table1.Rows[i]["ControlCatalogue"].ToString();
                string Num3 = table1.Rows[i]["Num3"].ToString();

                if(string.Equals(dt["ControlCatalogue"], ControlCatalogue))
                {
                    int temp1 = Convert.ToInt32(dt["Num4"]) - Convert.ToInt32(Num3);
                    dt["Num4"] = Convert.ToString(temp1);
                    int temp2 = Convert.ToInt32(dt["Num5"]) + Convert.ToInt32(Num3);
                    dt["Num5"] = Convert.ToString(temp2);
                }
            }
            boList.Add(dt);
        }
    }
    H3.DataModel.BizObjectSchema schema = this.Request.Engine.BizObjectManager.GetPublishedSchema("D000399SgUseAllPlan");
    H3.DataModel.BizObject schemaObject = new H3.DataModel.BizObject(this.Request.Engine, schema, this.Request.UserContext.UserId);
    schemaObject.ObjectId = UseAllPlan;  //更新的表單ID為UseAllPlan
    schemaObject.Load();
    schemaObject["D000399SgUseAllDetails"] = boList.ToArray();
    schemaObject.Update();
} 

上述代碼是根據ID，更新目標表單的子表數據，需要注意的是這里更新后的表單同樣會觸發它對應的業務規則，如果不想觸發業務規則，也可采用sql語句更新的方式，如下所示。

//將'項目信息'中項目成員賦值給‘我的項目’的項目成員
string sql1 = "update I_D000399SgProjectMy set I_D000399SgProjectMy.Members = (select Members from I_D000399SgProject "+
                "where I_D000399SgProjectMy.Project = I_D000399SgProject.Objectid)";
this.Engine.Query.QueryTable(sql1, null);

 

二、流程事件變化后執行某些邏輯

當一個表單生效或作廢后，若有業務規則首先會執行業務規則，通常有更新或新增等操作。然后再執行流程變化后事件。前提是當前表單已經開啟了表單流程。代碼如下：

 

protected override void OnWorkflowInstanceStateChanged(H3.Workflow.Instance.WorkflowInstanceState oldState, H3.Workflow.Instance.WorkflowInstanceState newState)
    {
        //流程審批結束,業務規則執行。還有個審批流程結束（finished狀態下直接刪除），就直接刪除也會觸發業務規則執行。在submit里面處理
        if(oldState == H3.Workflow.Instance.WorkflowInstanceState.Running && newState == H3.Workflow.Instance.WorkflowInstanceState.Finished)
        {
            DoAfterPass1(this.Request.BizObject.ObjectId);
        }
        //流程審批結束后，重新激活，業務規則會執行。還有個審批流程結束（finished狀態下直接刪除），就直接刪除也會觸發業務規則執行。在submit里面處理
        if(oldState == H3.Workflow.Instance.WorkflowInstanceState.Finished && newState == H3.Workflow.Instance.WorkflowInstanceState.Running)
        {
            DoAfterPass2(this.Request.BizObject.ObjectId);
        }
        base.OnWorkflowInstanceStateChanged(oldState, newState);
    }

 this.Request.BizObject.ObjectId; //當前表單的ID

三、發送消息提醒

H3.Task.UserTask task = new H3.Task.UserTask();
task.ObjectId = Guid.NewGuid().ToString();
task.Sender = this.Request.UserContext.UserId; //任務的發送人ID
task.UserId = this.Request.UserContext.UserId; //任務的接收人ID
task.AppCode = ""; //應用的Code
task.TaskType = H3.Task.TaskType.Reminder; //任務類型為提醒
task.SchemaCode = ""; //表單的Code
task.TargetType = LinkTargetType.BizObject; //鏈接類型
task.TargetId = ""; //鏈接表單對象的ID
task.TargetName = ""; //鏈接表單對象的名稱
task.Name = "這是測試提醒標題！"; //提醒標題
task.Summary = "這是測試提醒內容！"; //提醒的內容
task.AlertTime = DateTime.Now;  // 提醒時間
task.ReminderType = H3.Task.ReminderType.Once; //提醒的類型
task.StartTime = DateTime.Now;    //開始時間
task.TaskState = H3.Task.TaskState.Unfinished;  //任務的狀態
task.AlertState = H3.Task.AlertState.Waiting;  //提醒的狀態
this.Request.Engine.TaskManager.AddTask(task);//添加任務

至此是對氚雲部分功能的一個簡單介紹，后續會繼續說明其它部分功能所遇到的問題以及解決方法。
