I used pluggin Act as Taggable Steroid to create Tag In the table Tag,by default, There are only Tag and name. I have added column user_id to make personal tag(each user have their own tag). This is the old code to add tag by using Act as Taggable Steroid. @company.tag_list.add(params[:tag][:name]) The problem is ... i don''t know how to add user_id in tag column since i don''t find the way to modify it to do so. -- Posted via http://www.ruby-forum.com/.
