我如何在Grails中复制域对象？ [英] How can I duplicate a domain object in Grails?

问题描述

我想制作一个域对象的副本。什么是最简单的方法来实现这一点？

I want to make a copy of a domain object. What is the simplest way to accomplish this?

我意识到我可以创建一个新记录，然后遍历每个字段复制数据字段的字段 - 但我认为必须有一个更简单的方法来做到这一点...

I realize I could create a new record, and then iterate over each of the fields copying the data field-by-field - but I figured there must be an easier way to do this...

在Rails中，有一个简单的方法可以做到这一点：

In Rails there is a simple way to do this:

#rails < 3.1
new_record = old_record.clone

#rails >= 3.1
new_record = old_record.dup

Grails中是否有任何等价物？

Is there any equivalent in Grails?
