In my Ruby on Rails project, I have a Users table where each of them can tweet a tiny post to a group and people follows groups instead of single person. What i'd like to do is to create a blackList - meaning Person A can choose never to get tweets from person B (although they are both members of the same group). The way of doing many to many in RoR is actually very easy - "has_many XXXX through YYYY", but in this case i need to use the users table twice for each "pair" of blackList item.
在我的Ruby on Rails项目中，我有一个用户表，其中每个人都可以向一个组发送一条微博，而人们会跟随一个组而不是一个人。我想做的是创建一个黑名单——这意味着a可以选择不从B那里获取tweet(尽管他们都是同一组的成员)。对RoR中的许多用户执行“many to many”的方法实际上非常简单——“has_many XXXX to yyy”，但是在这种情况下，我需要对每个黑名单项的“pair”使用users表两次。
Any idea how to do such a thing?
