Hi all. I have 2 tables, one is work_times, and one is projects. I use a joint table to link 2 as they are has and belongs to many relationship . so there is a project_work_time. Now I need to add one column ''work_hours'' that is unique to each row of joint table project_work_time. I need to make a view such that for one specific work_time, it lists a series of projects and work_hours each projects is devoted on. If I left my hours inside joint table it seems it doesn''t work what we typically did in active record, or I am wrong? Please give me some guidance, and the best practice . the relationship is. projects <----->work_times work_times<-----hours projects <-----hours thanks. --------------------------------- DO YOU YAHOO!? 雅虎邮箱超强增值服务-2G超大空间、pop3收信、无限量邮件提醒 _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org lists.rubyonrails.org/mailman/listinfo/rails
