I have a Rails application that lists information about local services. My objectives for this model are as follows: 1. Require the name and tag_list fields. 2. Require one or more of the tollfreephone, phone, phone2, mobile, fax, email or website fields. 3. If the paddress field has a value, then encode it with the Geokit plugin. Here is my entry.rb model:

class Entry < ActiveRecord::Base

  validates_presence_of :name, :tag_list
  validates_presence_of :tollfreephone or :phone or :phone2 or :mobile or :fax or :email or :website
  acts_as_taggable_on :tags
  acts_as_mappable :auto_geocode=>{:field=>:paddress, :error_message=>'Could not geocode physical address'}

  before_save :geocode_paddress
  validate :required_info

  def required_info
    unless phone or phone2 or tollfreephone or mobile or fax or email or website
      errors.add_to_base "Please have at least one form of contact information."
    end
  end

  private
  def geocode_paddress
    #if paddress_changed?
    geo=Geokit::Geocoders::MultiGeocoder.geocode (paddress)
    errors.add(:paddress, "Could not Geocode address") if !
geo.success
    self.lat, self.lng = geo.lat,geo.lng if geo.success
    #end 
  end
end

Requiring name and tag_list work, but requiring one (or more) of the tollfreephone, phone, phone2, mobile, fax, email or website fields does not.

As for encoding with Geokit, in order to save a record with the model I have to enter an address. Which is not the behavior I want. I would like it to not require the paddress field, but if the paddress field does have a value, it should encode the geocode. As it stands, it always tries to geocode the incoming entry. The commented out "if paddress_changed?" was not working and I could not find something like "if paddress_exists?" that would work.

Help with any of these issues would be greatly appreciated. I posted three questions pertaining to my model because I'm not sure if they are preventing each other from working. Thank you for reading my questions.
