(.rb) class reseller < activerecord::base attr_accessible :blah, :blah, :contact_email this one: before_save { |reseller| reseller.contact_email = contact_email.downcase } and this: before_save { contact_email.downcase } thank you the first sets value back persisted property (or @ least should; i'd double check). the second downcases , nothing result. if second read contact_email.downcase! should modify actual property. http://apidock.com/ruby/string/downcase http://apidock.com/ruby/string/downcase%21 the "bang" method follows ruby convention of naming destructive methods, e.g., methods alter underlying data, trailing ! . note: tadman points out, you'd need vet against ar tests make sure app still functions expected, since may bypass of ar's magic.
