you need to do something like

class << ActiveRecord
alias “id__”, “id”
end

Hi,

Thanks for your answer. I see now where the problem comes from, but your
“trick” is apparently not sufficient. The code…

class Garden < ActiveRecord::Base
include DRbUndumped
has_many :flowers
alias :id__ :id
end

class Flower < ActiveRecord::Base
include DRbUndumped
belongs_to :garden
alias :id__ :id
End

… Still does not work…

Hey Philip-

I have dealt alot with ActiveRecord over drb, I use it in this

plugin for rails[1] . The way around this is to use a different
notation to get the id of the AR object. So with your client example
change it to this and you will be fine:

#!/usr/local/bin/ruby
require ‘drb’

DRb.start_service()
obj = DRbObject.new(nil, ‘druby://localhost:9000’)

g = obj.find(1)
puts “#{g[:id]} | #{g.name}”
g.flowers.each do |f|
puts “#{f[:if]} | #{f[:id]} | #{f.name}”
end

So by using arinstance[:id] instead of arinstance.id you will avoid

this problem all together.
