#        # adds accepts_nested_attributes_for dependency to the question model, which triggers the dependency validations
#        # This means we do need to account for adding new records, and the validation has to be modified.  Unfortunately,

Instance Method Details

#question_group_id=(i) ⇒ Object

need to overwrite the following methods because they rely on the nil? method. Actually, the parameter comes back as a string and even an empty string will not evaluate to nil. Changed to blank? instead.
