我有这个与 1:m 关系的表，所以一只股票可以有一个或多个 stock_details。这就是我构建实体的方式：

在我看来，我正在尝试访问这些值：
{{ entity.getStockDetail.getAmount }}
{{ entity.getStockDetail.getPrice|number_format(2, '.', '') }}
但我得到了这个错误：
渲染模板期间引发异常（“在 'StockBundle\Entity\KStock' 上找不到映射到列 'id' 的字段。该字段不存在或关联存在但它有多个连接列.") 在 ProductBundle:Default:index.html.twig 第 52 行。
关系有什么问题？
