[Rails] Re: NoMethodError

Ok, now I got it, the code is below, but now I have the follow error:

Attempt to call private method

I dont know if it is related with this error, but this table is a
legacy and I had to set table name and primary key.

The model is :
class Cartcid < ActiveRecord::Base
set_table_name "cartcid"
set_primary_key "NUMERO"
end

namespace :GeoFind do
desc 'Update cartcid with longitude and latitude information'
task :add_cartcid_coordinates => :environment do
include GeoKit::Geocoders
c = Cartcid.find_by_sql(["SELECT address, lat, lng FROM
cartcid WHERE ADDRESS IS NOT NULL"])
begin
c.each { |cartcid|
loc = MultiGeocoder.geocode(cartcid.address)
cartcid.lat = loc.lat
cartcid.lng = loc.lng
cartcid.update
puts "updated cartcid #{cartcid.nome}
#{cartcid.address} =>
[#{loc.lat}, #{loc.lng}]"
}
rescue
puts $!
end
end
end
