在has_and_belongs_to_many上进行版本控制？
[英]versioning on a has_and_belongs_to_many?
问题描述
Is it possible at all to have versioning for has_and_belongs_to_many associations? 
是否可以对has_and_belongs_to_many关联进行版本控制？ The official documentation only briefly mentions has_many and belongs_to . 官方文档仅简要提及has_many和belongs_to 。 I have added papertrail on both ends of my has_and_belongs_to_many association, run the migrations and whenever I update the association from either end, nothing ever gets added to the version_associations table. 我在has_and_belongs_to_many关联的两端添加了papertrail，运行迁移，每当我从任一端更新关联时，都没有任何东西被添加到version_associations表中。 Could someone point me in the right direction? 有人能指出我正确的方向吗？

Yes. 是。 HABTM reification was added very recently (2016-04-25) in PR 771 and released in version 5.0.0 . 最近（2016-04-25）在PR 771中添加了HABTM reification，并在5.0.0版本中发布 。
The official documentation [does not mention HABTM] ..
That's correct. 那是对的。 We'd appreciate contributions to that documentation, thanks! 我们非常感谢对该文档的贡献，谢谢！
