Hi all,
I'm using the latest rails 2.3.5 and put some models in subfolders like this:
models/my/details/texts.rb
models/my/details/attributes.rb
...
The models themselves are defined like this:
class My::Details::Texts < ActiveRecord::Base
....
class My::Details::Attributes < ActiveRecord::Base
...
In development mode (using webrick), everything works fine. But in production mode (using thin), I get these errors:
A ArgumentError occurred in attributes#show:
My::Details is not missing constant Attributes!
/var/lib/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:417:in `load_missing_constant'
A ArgumentError occurred in attributes#show:
My::Details is not missing constant Texts!
/var/lib/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:417:in `load_missing_constant'
So I wonder if it's okay to place models in subfolders at all? If yes, why does this error occur and how to fix it?
Thanks,
Corin

Historically, models in subfolders have caused problems, but they
should work now. Can you post a complete stack trace for either of
these errors?

Same backtrace without line breaks (hopefully):
