You are actually illustrating the point to state machines. Yes, in this simple example you can implement them using a series of conditionals, but not every state machine is this simple. You could end up with a lot of conditionals and the code could end up being difficult to follow. Good design is not always about producing the fewest number of lines. Sometimes a more verbose and descriptive code can improve maintainability. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
