Importing (bootstrapping) the initial data from fixtures(.yml) with foreign keys in Rails 2.0


I'm trying to import data from YAML files in Rails 2.0.2. I learned
that new features came out for fixtures at RailsCasts .

And, in Rails 1.2.6 and before, I used a "rake" task I found online.
Looks like there are many variations for this "bootstrap" file.

Do you know if there's a file available that does something similar
(i.e., importing data to development/production database) for Rails
2.0.2 and deals with foreign keys automatically?

Any help would be greatly appreciated.
