Ideas for implementing an UI for set combinations in rails


  Iam rails newbie. I have to implement a UI design for 3 tables based on set theory.   I thought a lot of a lot of ideas in the past few days but nothing seemed to fulfil my necessity

  Say i have tables a, b and c   I should be able to do like

  a n b   a u b   b - a   (b - a) n c   etc....

  If any web developers well versed in ui designs out there have some suggestions of doing it, i would   appreciate it :slight_smile:

I don’t fully understand. For example when you ask for the intersection ‘a n b’ do you mean all records that are the same in the two tables or the intersection of the fields of the tables (ie fields that exist in in both tables). If you mean those records that exist in both, do the tables have all the same fields? Or maybe a combination of both.
