No reverse relationship when using collection_of?

[yangtheman]

When using has_many and belongs_to relationship in ActiveModel, having one relationship means reverse is automatically created. For example, if I have a has_many :bs and b belongs_to :a, I could find b's using a.bs and a using b.a.

However, it CouchRest Model, it doesn't seem to be the case, so I would need to set the reverse relationship explicitly. For example, if I have a collection_of :bs and b belongs_to :a, I would have to explicitly say b.a = a after I create a with a bunch of b's.

Is this correct? I just want to make sure I am not missing some obvious way to establish has_many and belongs_to relationship in CouchRest Model.
