when we have validate_presence_of :name in the model and then when we put in the create action that we re-render 'new', then the form_for will populate the fields, and error_messages_for 'story' will have the correct error message.
this is really great, and and the same time, this looks like magic... i found that many books don't explain how the magic occur. is it by some global variable? when the form_for is called... is it using the @story that came back from the @story.save, instead of the @story = Story.new from the new action? sometimes i feel that i am playing magic when using Ruby on Rails, except I don't know how the magic happens... kind of like if I make the rabbit appear, but I don't know how I did it. So I really want to know the inner workings of Rails. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
