Question

JHipster没有为数据库创建表 DatcatAttributeMetadata 。这是一个子表，其外键关系manyToOne与父表DatcatAttributeMetadata。父表是先前创建的，但是在使用Jhipster实体模块添加DatcatAttributeMetadata时，此表未添加到PostgresSql并抛出错误ERROR：relation＆＃34; datcat_attribute_metadata＆＃34;不存在

已尝试过--force-entity和mvn liquidbase：diff多次但仍未在DB中创建表

以下是

的代码段

请不要通过更改liquidbase文件并在域类中使用@Column注释，将父表和子表中主键的列名更新为dataset_id和attribute_id。

JHipster：Relation＆＃34; datcat_attribute_metadata＆＃34;不存在
