I am trying to create active record schema that includes self referential many to many. Example. I have models Group and Person. Person can belong to multiple groups and that isn't the problem here. Problem is that I want groups to be able to have both groups as well as people as members. And groups can be subgroups in several parent groups at the same time (so if I understood correctly ActsAsTree won't work in this situation) I tried to do it with has_many, :through as well as with :polymorphic. But wasn't succesfull. So my question is that is this at all possible or should I look for workaround to this problem? Code can be found from pastebin: http://pastebin.com/f1fc609d3 All suggestions appreciated.

Thanks for that. I found a way to achieve this from this blogpost: http://blog.hasmanythrough.com/2007/10/30/self-ref...
