This is probably a dead thread, but... i think the answer given is incorrect.
'order_with_respect_to' adds an '_order' integer field to the model. Each set of instances that share a parent object of the relation specified by 'order_with_respect_to' get ordered as a set. So in the example, three Answer instances with fk's to one Question instance will have '_order' values of 0, 1, and 2, which represent their (specified) ordering "with respect to" that Question instance. i'd be curious to know if anyone has seen an admin implementation for reordering with this field. i'd also heard some chatter a while back that this might be removed in future releases of Django, because it leans toward the "magic" end of things. shannon On Nov 30, 3:20 pm, Preston Holmes <pres...@ptone.com> wrote: > On Nov 29, 4:50 pm, Continuation <selforgani...@gmail.com> wrote: > > > In the doc (http://docs.djangoproject.com/en/dev/ref/models/options/ > > #order-with-respect-to) it is mentioned that order_with_respect_to > > marks an object as "orderable" with respect to a given field. > > > What exactly does that mean?
