Guys, I''m having a problem getting acts_as_tree working. It seems from the Agile book (p. 255) that acts_as_tree only supports one-to-one record relations, whereas I need many-to-many support. In other words, looking at the picture at the top of page 256 where where only 1 id is linked to 1 parent_id, I need multiple id''s linked to multiple parent_id''s - for example, id = 6 linked to not only parent_id 3, but also parent_id 7 and 5 (not really parents, just linked). Obviously w/the id column being a primary key, duplicate values of id = 6 isn''t going to work. Any suggestions on getting this to work? -- Posted via http://www.ruby-forum.com/.

Even in this early stage, the book is well worth its price. Best regards Peter De Berdt
