hibernate - Grails: hibernate 和数据迁移

Question

我有一个针对客户的域类。我最近不得不更改为域类，因为我们正在收集帐单邮寄地址和收货地址，但只记录一个邮政编码值。所以我认为这是一个简单的解决方法。将邮政编码更改为billzipcode，然后为shipzipcode创建一个新字段。我运行dbm-gorm-diff来创建更改日志，然后运行dbm-update来执行我所做的更改。到目前为止，一切都可以顺利进行。但是然后我去调试该应用程序，以查看对数据源的更改是可以的。但是，现在当我尝试保存新的客户记录时，出现此错误:

    NULL not allowed for column "ZIPCODE"; SQL statement:
insert into customer (id, version, billaddr, billcity, billstate, billzipcode, cell, contact, country_id, custcode, custname, date_created, email, fax, last_updated, organization, phone, shipaddr, shipasbill, shipcity, shipstate, shipzipcode, status, tenant_id) values (null, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [23502-164]. Stacktrace follows:

我很茫然，因为ZIPCODE列不再在域类中。任何指导将不胜感激。

Answer 1

如果您注意到更改集，那么billzipcode的条目实际上是在添加新列，而不是重命名zipcode列。因此，您仍然必须管理数据迁移。这样的事情应该在您的情况下工作:

changeSet(author: 'user (generated)', id: '1363806498118-4') {
    comment { 'Renaming zipcode to billzipcode' }
    renameColumn(tableName: 'customer_costs', oldColumnName: 'zipcode', newColumnName: 'billzipcode', columnDataType: 'varchar(50)')
}
