Question

Can someone please point me to the right direction.

I’m using after_validation to compete geocoding and I wanted to know how I can tact on an or || option to an if clause.

This works as intended

class Address < ActiveRecord::Base

after_validation :geocode, if: :address_changed?

But this doesn’t

class Address < ActiveRecord::Base

after_validation :geocode, if: :address_changed? || :zipcode_changed?

Thanks in advance.

If you don’t want to use Thilo’s Proc approach then you can add your own custom method and use that:

class Address < ActiveRecord::Base
  after_validation :geocode, if: :address_or_zip_changed?
private
  def address_or_zip_changed?
    address_changed? || zipcode_changed?
  end
end

This may (or may not) read better and is handy if you need the same compound condition on multiple validations.
