I am developing a Rails 1.0 application (I can't upgrade, it's a strange situation) for which I am trying to use the :composed_of functionality. I have a class called StreetAddress:
class StreetAddress
attr_reader :address, :address2, :city, :state_id, :zip_code
def initialize(address, address2, city, state_id, zip_code)
@address = address
@address2 = address2
@city = city
@state_id = state_id
@zip_code = zip_code
end
end
and a model class called Hotel
class Hotel < ActiveRecord::Base
composed_of :street_address
# ...
end
which has columns:
"id", "brand_id", "code", "location_name", "address", "address2", "city", "state_id", "zip_code", "phone_number", "phone_ext", "fax_number", "time_zone", "url", "room_service_email", "manager_name", "manager_email"
However when I try to access the aggregation I get an error:
>> h = Hotel.find(1)
=> #<Hotel:0x38ad718 @attributes={"fax_number"=>"1-623-420-0124", "city"=>"Twin
Falls", "address2"=>"285", "brand_id"=>"1", "code"=>"XZWUXUSZ", "manager_email"=
>"[email protected]", "url"=>"http://www.xycdkzolukfvu.hom", "ph
one_number"=>"1-805-706-9995", "zip_code"=>"72436", "phone_ext"=>"48060", "id"=>
"1", "manager_name"=>"Igor Mcdowell", "room_service_email"=>"Duis.risus@Donecvit
ae.ca", "time_zone"=>"America/Boise", "state_id"=>"15", "address"=>"P.O. Box 457
, 7405 Dignissim Avenue", "location_name"=>"penatibus et magnis"}>
>> h.street_address
ArgumentError: wrong number of arguments (1 for 5)
from (eval):3:in `initialize'
from (eval):3:in `new'
from (eval):3:in `street_address'
from (irb):6
Why?
