Rails3: ActiveRecord model relationship with YAML file

Question

Hi,

I have an ActiveRecord model Group and a YAML table stored in config/users.yaml just like:

- {login: titi, password: 123456, group_id: 2}
- {login: toto, password: 987654, group_id: 7}

And I would like to link them by a sexy way. Can you help me?

I would be happy if I can do this (as example):

User.first.group.id # => 2

Many thanks for any help!
