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.
