Sorry if this response is a bit off the question's topic, but I do have an unrelated suggestion. You have the following line in your sample code: > if self.status > 3 # anything above 3 should be saved I would recommend against this use of "magic numbers," such as "3" in this case. The number 3 has no meaning here. I would recommend that you use something like a "finite state machine." http://en.wikipedia.org/wiki/Finite_state_machine There is a Ruby gem implementation of this: http://github.com/rubyist/aasm/tree/master Now the same line of code can be written as: if self.completed? Now there is no ambiguity on the meaning of some "magic number." The code clearly states its intent. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
