The error_messages_for helper displays the name of the model attribute (the field of the database) followed by the message set in the validation line. You can roll out your alternative to error_messages_for by using the methods listed at http://api.rubyonrails.org/classes/ActiveRecord/Errors.html It's quite easy.

Instead of using validates_presence_of you could do the validation manually and customize the error message.

private   def validate     if(self.city == nil || self.city == '')       errors.add_to_base("Please enter city")     end   end

However, by using "add_to_base" you will not be able to highlight which field contains the error.
