保存数据的问题

tlkj

保存数据时，需要保存登陆者、登陆时间、更新者、更新时间；是不是只能模仿下面的方法，还说有没有其他更好的方法
public static void busTypeProcessBeforeSaveRB_BusTypeAction() {
       //获得table参数
             Table table = (Table)ContextHelper.getActionContext().getParameter("table");
             //获得所有新增的行
             Iterator<Row>   rows = table.iterator(com.justep.system.data.ModifyState.NEW );   
             SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy");
             String date = sDateFormat.format(new java.util.Date());      
                while (rows.hasNext()){
                       Row row = rows.next();  
                        String a=BizUtils.createNextSequenceString("CDRS"+date,"0000");   
                        row.setValue("busTypeId",a); //给列赋值
                }
}

可以在data的保存事件中操作，或者就是上面的在action的执行事件中操作

如果是新增的时候记录，可以在ontology中直接设置默认值

为什么不进我的action

public static void makingVoucherProcessBeforeSaveCw_kjkmAction() {
                // 获得table参数
                Table table = (Table) ContextHelper.getActionContext().getParameter("Cw_kjkm");
                // 获得所有新增的行
                Iterator<Row> rows = table.iterator(com.justep.system.data.ModifyState.NEW);
                System.out.println("------------------------------------");
}

确认是否报错了

tlkj

没有报错

jishuang

在data的保存事件中加alert看看是否执行了

tlkj

没有执行

jishuang

把执行那就是data中设置的不正确，确认调用的是否正确，data的write设置的是否正确

tlkj

不好意思啊，刚才弄错了。重新给你发一下

代码：
public static void makingVoucherProcessBeforeSaveCw_kjkmAction() {
  // 获得table参数
  Table table = (Table) ContextHelper.getActionContext().getParameter("Cw_kjkm");
  // 获得所有新增的行
  Iterator<Row> rows = table.iterator(com.justep.system.data.ModifyState.NEW);  
  while (rows.hasNext()) {
   Row row = rows.next();
   row.setValue("GXZ","test");
  }
}

AccountProcess.accountProcessBeforeSaveCw_kjkmAction(AccountProcess.java:20)

已经报出来那行报错了，java代码中打断点调试一下看看啊
