one_to_many associations can only have associated objects if none of the :keys options have a nil value.

Whether the reciprocal of this association returns an array of objects instead of a single object, false for a one_to_many association.

The one_to_many association needs to check that an object to be removed already is associated.

One to many associations set the reciprocal to self when loading associated records.
