Look at the documentation for this validation:
http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M001336
"If you validate the presence of the associated object, you will get
failures on saves when both the parent object and the child object are
new."
o.olive_oil_sources << os
will not save 'os' because 'o' is a new record.
I don't know if this is a chicken or egg thing you've got going here
or not. You might have to enforce the required associations for
OliveOil a different way.
Have your controller or model generate all the relevant objects; maybe
save them in a transaction.
Then you have to test for situations where all the olive oil sources
for an olive_oil are deleted to ensure that this type of situation
can't occur (or rethink this requirement). etc etc -
You could probably do this with a validation because I think you can
stipulate when the validation occurs eg at creation time, at update
time etc So rewrite the validation to take effect only when updating.
I would do all this testing in the models (test/units) myself.
