has_many and validates_associated
By trial and error I seem to arrive to the conclusion that
1. Validation recurses through has_many by default and
a root save! call raises an excepcion if some child no
matter how nested is fails validation
2. Validation does not recurse through has_one by default
and you can change this with validates_associated, in
which case exceptions behave like above
