Ruby on Rails

Ok,

Thank you. I read Rails Guide on ActiveRecord Validations and
Callbacks, specifically Conditional Validation.

So,
validates :question, :presence => true, :if => "question_type.blank?"
placed inline in model should be the simplest way to do this. It does
not work however. My lack of understanding seems to be related to how I
specify question_type in the condition?

As you can see i'm still on the bottom of the steep part of the learning
curve.'

Thanks for the help
