我有一个名为DraggableAsset的组件,它由DragSource修饰:

@DragSource('DRAGGABLE_ASSET', spec, (connect, monitor) => ({
  connectDragSource: connect.dragSource(),
  isDragging: monitor.isDragging(),
}))
export default class DraggableAsset extends Component {
  static propTypes = {
    asset: PropTypes.instanceOf(AssetModel).isRequired,
    connectDragSource: PropTypes.func.isRequired,
    isDragging: PropTypes.bool.isRequired,
  };

  render() {
    const {isDragging, connectDragSource, asset} = this.props;
    return connectDragSource(
      <div style={{opacity: isDragging ? 0.5 : 1}}>
        <img width={200} src={asset.get('url')} />
        <p>{asset.get('name')}</p>
      </div>,
    );
  }
}

我想参数化'DRAGGABLE_ASSET'字符串。我可以用下面的另一个装饰器来实现吗?

export function DraggableAssetDecorator(target, name, descriptor) {
  Object.defineProperty(target, 'TYPE', {value: 'DRAGGABLE_VIDEO'});
  return target;
}
