Ambition and models derived from ActiveRecord

[Allan]

Hi,

some of my models are derived from classes that derive from
ActiveRecord:

class InfoDBModel < ActiveRecord::Base
# Stuff to change table name and even sometimes
# database name and force column reloads when that happens!
end

class Portal < InfoDBModel # (normally ActiveRecord::Base)
# ...
end

and when I use Ambition I get:

>> Portal.select{|z| z.user == 'acochran'}.to_s
ArgumentError: wrong number of arguments (2 for 1)

api.rb:9:in `select'

Whereas it all works fine if I don't derive from InfoDBModel.

Any ideas on how to overcome this?

Thanks,

Allan

I found I was getting this because I had the wrong version of a
dependency. I think in my case it was ParseTree. I'm using
ParseTree-2.1.1, ruby2ruby-1.1.7, RubyInline-3.6.6 and rubigen-1.1.1
