It's kind of unclear about what you are trying to do here. Say you have
a model like so:
class Customer < ActiveRecord::Base
# contains attributes :fname, :lname, :phone, :city, :state, :zip
validates_presence_of :fname, :lname, :phone, :zip
end
This model will validate the presence of the 4 fields (:fname, :lname,
:phone, :zip). Would this be comparable to the "longer" version?
If so, would the shorter version be required to ONLY validate a subset
of the validates_presence_of list? Perhaps only :fname & :lname?
If this is the case you can just set the default validations to the
short list like so:
validates_presence_of :fname, :lname
In order to get the long validation, you can do this with your model:
class Customer < ActiveRecord::Base
# contains attributes :fname, :lname, :phone, :city, :state, :zip
validates_presence_of :fname, :lname
@long_validation
attr_accessor :long_validation
def validate
if @long_validation
errors.add("phone number cannot be blank") if phone.blank?
errors.add("zip code cannot be blank") if zip.blank?
end
end
end
Test this using your script/console from the terminal.
