Rails - Oct 2009 - Problem with composite primary keys, fixtures

Hi,

Rails 2.3.4
Composite Primary Keys 2.3.2

I''m having trouble loading fixture data for models with composite
primary keys.

NoMethodError: You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.first
    vendor/gems/composite_primary_keys-2.3.2/lib/
composite_primary_keys/base.rb:261:in `find_from_ids''
test/unit/site_location_test.rb:10:in `setup''

# site_location.yml

zzustest-sch01:
  schoolid: ZZUSTEST
  siteid: SCH-01
  latitude: 29.4266
  longitude: -98.54788
  elevation: 224.3
  datasource: 1
  uttimestamp: <%= Date.new(2009, 6, 18) %>
  enteredelevation: 198

# line 10 of the setup method
@record = site_location(''zzustest-sch01'')

Has anyone else seen this?

Regards,

Dan

Try: @record = site_location(:zzustest-sch01)

symbol, not string

That''s partly because fixtures are poorly implemented and create more 
problems than they solve.  Consider Machinist instead.

I don''t think it matters, but I tried it just in case. Same error.
