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:insetup’

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.
