data.rims.add(req.POST.getlist('rims'))
should do what you need it to do, assuming what has been posted is a
list of valid primary keys or object instances.
data.rims is a descriptor; it behaves a lot like an attribute (because
it has __get__ and __set__ implementations), but it also has some
helpful utility methods (like add(), remove() and clear()).
