Re: Saving related table data

I am in the process of acquainting myself with Cake and have come
across a question related to `koala kid`'s. Namely, to explore the
$hasOne relationship:

-- I baked two models, Parental and Dependent, where parental_id is a
foreign key in `dependents` that references `parentals`.`id`.
-- Apart from `id`s, each model only has a `name` field.
--When I set the Parental model to $hasOne Dependent, I able to use
the standard baked controllers to add more than one Dependent to a
Parental. The Dependent model is associated by $belongsTo. Why is this
the standard behavior for this association?
