Question

我在jhipster中定义的一对一关系中有此异常：

org.hibernate.AnnotationException: Unknown mappedBy in: 
com.plan.vima.domain.Warehouse.orderItem, referenced property unknown: 
com.plan.vima.domain.OrdemItem.ordemItem

这是我添加的关系并导致了我的问题：

 relationship OneToOne {
      OrdemItem to Warehouse {orderItem}
 }

请注意，在导入项目和关系后，jhipster对项目进行了处理，因此我在运行该项目时遇到了此异常-我没有编写任何代码。

这是我完整的Jhipster项目信息：

Answer 1

我认为应该是这样的：

for cat in categories:
    for column in '{}_feature_columns'.format(cat):
        print (column)

因为关系的所有者是OrdemItem。
