before_validation :capitalize_first_words
def capitalize_first_words
[:question, :correct_ans_1, :correct_ans_2, :correct_ans_3].each do
|key|
self.key = key.to_s.gsub(/^(\W*?[a-z])/) { |m| m.upcase } if
!key.to_s.blank?
end
end
Note the difference betweet self.key and key.
self.key calls method key on self.
key - is block local variable, which is instance of Symbol ( :question,
:correct_ans_1 ...).
Symbol has not methods '.gsub' and '.blank?', so it must be converted to
String to call '.gsub' and '.blank?'
