Hi!, I know that Rails do not save in cascade so I need to solve this problem: I have invoice that has lines. Invoice have fields that are calculated with values of lines so when a line is modified or deleted I need to update the invoice, how I do that automaticaly? If I use before_save on invoice it does nothing because it does not detect that a line related is modified. Is the best solution to use a after_save on line that updates the invoice? -- Posted via http://www.ruby-forum.com/.
