Hi, here is a model code:
class Address < ActiveRecord::Base
validates :firstname, :lastname, :address1, :city, :zipcode, :country,
:phone, :presence => true
attr_accessible :firstname, :lastname, :address1, :address2,
:city, :zipcode, :country_id, :state_id,
:country, :state, :phone, :state_name,
What are the guides to override *validates*?
For example, I don't want *zipcode* to be validated.
