您可以通过使用GanttSheet资源功能高效地管理任务、日程和资源。利用GanttSheet资源,您可以指定哪些资源分配给哪些任务,并将不同的任务分配给不同的资源。
通过在GanttSheet中列出项目所需的所有资源并将它们与任务链接,可以更准确地估算和跟踪任务的发展。此外,通过优化资源的分配和利用,您可以提高项目的效率和效果,并适当管理成本。
让我们详细讨论GanttSheet资源功能。
要使用资源功能,首先需要设置资源和分配的相应数据源,以创建必要的关系。
您可以使用任务、分配和资源表通过关系添加资源。此外,任务和分配表之间的关系必须有源名称和目标名称。资源列可以直接从配置的关系中检索资源名称。
以下示例代码添加了TaskResources的dataType,它在资源列中添加了一个下拉框。
dataManager.addRelationship(assignmentTable, "taskId", "task", taskTable, "id", "taskId");
dataManager.addRelationship(assignmentTable, "resourceId", "resource", resourceTable, "id", "assignment");
ganttView = taskTable.addView("ganttView", [
{ value: "id", caption: "ID", width: 60 },
{ value: "parentId", caption: "PID", width: 60 },
{ value: "taskNumber", caption: "Task Number", width: 120 },
{ value: "mode", caption: "Mode", width: 65 },
{ value: "name", caption: "Task Name", width: 200 },
{ value: "duration", caption: "Duration", width: 90 },
{ value: "predecessors", caption: "Predecessors", width: 120 },
{ value: "taskId.resource.name", caption: "Resources Name", dataType: "TaskResources", width: 300 },
]);
ganttView.fetch().then(function() {
ganttSheet.bindGanttView(ganttView);
});
上述代码的输出将在GanttSheet顶部显示相应的资源名称,如下图所示。
GanttSheet允许您通过使用资源列来分配资源。
GanttSheet的资源列显示了所有资源的内容,如下图所示。
当您拥有资源名称列和资源表被绑定时,当前列的单元格类型将在下拉菜单中显示所有现有资源。您可以使用下拉菜单向活动任务添加和更新资源。所有对分配的更新将导致分配表中的更改。GanttSheet首先将当前操作分解为多个插入和删除操作,然后生成必要的更改,最后将它们存储在分配表上。
另外,您还可以从GanttSheet中删除任务和资源。请注意,删除一个任务或资源可能会同时移除多个相关的分配。
一旦所有更改完成,您需要提交您所做的所有分配更改。如果没有资源,只会更改当前视图。但是当添加资源时,需要提交分配信息,然后将任务与分配信息一起提交。您必须同时提交任务的更改和分配表的更改到Ganttsheet.submitChanges中。
资源表只能在TableSheet中更改。要更新在GanttSheet中使用的资源的内容,您必须将当前的修改提交到数据源以再次检索相关内容。
只有当资源表将最新的修改提交到数据库后,GanttSheet才必须再次检索资源数据,以准确更新资源列下的资源。
将资源分配给任务不会影响其持续时间,但会增加当前任务的工作时间。
任务的工作时间代表分配给当前任务的所有资源的工作时间,默认单位是小时。
要添加一个工作时间列,您需要在视图上方添加一个名为"workTime"的列。例如,如果一个任务当前的持续时间为1天,并且有2个资源同时在其上工作,则该任务的工作时间为2天。每天的工作时间是8小时,所以当前任务的总工作时间是16小时。
var view = taskTable.addView("ganttView1", [
...
{ value: "workTime" },
...
]);
type=info
注释:
在一个普通任务中,当前工作时间是持续时间乘以资源数量。
在一个汇总任务中,当前工作时间是持续时间乘以资源数量,然后加上所有子节点的工作时间。
如果当前汇总任务没有资源,那么它的工作时间是所有子节点的工作时间之和。
你可以使用以下步骤在SpreadJS设计器中添加和更新GanttSheet资源。
点击数据(DATA)选项卡以添加数据源(DataSource)
在数据源窗口中添加任务(Task)、资源(Resources)和分配(Assignment)表格
添加任务和分配
在taskId列中添加一个关系
将id列设置为任务表的主键
添加资源和分配
在resourcesId列中添加一个关系
将id设置为资源表的主键
添加工作时间列
添加资源列
请注意,列值是“TaskTable_id.AssignmentTable_resourceId.name”,这意味着任务表目标关系名指向分配表的源关系名。
添加带资源的GanttSheet
更新资源
资源列是只读的,因为它是使用计算列添加的。你必须移除只读状态以更新资源
