创建实体数据时如何自动添加选中的父类

Jmix
#1

已经通过重写 CreateAction 实现了功能，但感觉不优雅，是否可以通过Editor类的onInitEntity事件去设置选中的父类呢？这个就需要获取选中的数据

当然可以在 onInitEntity 方法中给实体属性赋值。这里关键问题是什么？如何获取选中的数据？

是的，求教 :handshake:

  • 也许不需要重写 CreateAction 就可以对弹出的 Edtior 进行配制，参考以下代码：
        CreateAction<Attachment> createAction = (CreateAction<Attachment>) table.getAction("create");
        
        createAction.setScreenConfigurer(screen -> {
            ((AttachmentEdit) screen).getCategoryField().setVisible(true);
            screen.addAfterShowListener(afterShowEvent -> {
                Category currentItem = categoryTree.getSingleSelected();
                ((AttachmentEdit) screen).getCategoryField().setValue(currentItem);
            });
        });
  • 获取 TreeTable 的选中项 用 TreeTable.getSingleSelected()

搞定:handshake:

@Autowired
private lateinit var materialTypesTable: TreeTable<MaterialType>


@Install(to = "materialTypesTable.create", subject = "screenConfigurer")
private fun screenConfigurer(screen: Screen?) {

    screen!!.addAfterShowListener {
        val singleSelected = materialTypesTable.getSingleSelected()

        (screen as MaterialTypeEdit).editedEntity.parent = singleSelected
    }

}
