我是mongoid的新手.我在Ryan Bate的屏幕演员#238的帮助下开始用
rubyonrails做mongoid.
我在mongoid官方网站的“参考”部分中找到了描述has_many的部分.
任何人都可以帮我解释一下has_many和references_many之间的区别是什么以及哪个版本的mongoid支持它们.
非常感谢你.
解决方法
从mongoid doc你可以读到：
http://mongoid.org/docs/upgrading.html
Relational associations no longer autosave when the parent relation is
created. PrevIoUsly a save on a new document which had a
references_many or references_one association loaded would save the
relations on it’s first save. In order to get this functionality back,
an autosave: true option must be provided to the macro (This only
applies to references_many and references_one):
所以现在我认为没有差异,你可以免费填写使用has_many和选项autosave：如果你需要:)
