wrong number of arguments (2 for 0) on first invocation, using bundler without rails

[Troy Kruthoff]

class AccountUser < ActiveRecord::Base
self.primary_keys :account_id,:user_id
end

console:


>> AccountUser.all
ArgumentError: wrong number of arguments (2 for 0)

Any ideas? The first call to primary_keys always fails, but after
than everything is just dandy!

Thanks,

self.primary_keys= ?  When did that become the thing to use?  I've been using this gem since it first appeared, and it was always:

set_primary_keys [:account_id,:user_id]

ActiveRecord 3.2 deprecated[1]

set_primary_key :account_id

in favor of

self.primary_key = :account_id

CPK 5.0 permits[2] self.primary_keys= to follow this pattern.

So, Tony, you need to write:

self.primary_keys = [:account_id, :user_id]

(Note the '='.)

Thanks, Rhett.  I was afraid I'd missed something.  But I haven't moved to 3.2 yet, so not so much ;-)
