Description of model

In each model - address_type as well as address_id Each model will be 'addresssable'

##Tests

simple association methods

Company.first.addresses Person.first.addresses Address.first.addressable Address.second.addressable

re-assigning and adding to associations

Company.first.addresses.build(:street_address => Faker::Address.street_address, :address_line_2 => Faker::Address.community, :postcode => Faker::Address.zip_code, :addressable_id => "Company", :addressable_type => Company.last.id) Company.second.addresses << Address.second Person.second.addresses << Address.third Company.second.address_ids # ids

de-associating

Company.second.addresses.delete(Address.second)
