我试图ToMany在创建时通过 a 和一些复杂的数据处理来保存相关的资源，并想找出将我的巨型 kludgy obj_create 重构为在美味派范式中有意义的东西的最佳方法。

目前，我的obj_create样子是这样的：

@transaction.commit_manually
def obj_create(self, bundle, **kwargs):
    sid = transaction.savepoint()
    try:
        data = self.deserialize(bundle.request, bundle.request.body)
        related_data = data.pop('related')
        ## get_or_create the related objects by processing the data passed
        related_objs = self.create_related_objs(related_data)

        ## Create the object the above are related to
        obj = self._meta.object_class.objects.create(**data)  # this has been cleaned of non-object keys
        for (order, related) in enumerate(related_objs):
            ObjRelation.objects.create(obj=obj, related=related, order=order)
    except:
        transaction.savepoint_rollback(sid)
        raise Badrequest("you fail it")
    bundle.obj = obj
    bundle.data = data
    transaction.savepoint_commit(sid)
    return bundle

所以这是我正在做的一个相当简化的版本。我相信将相关的保存移到 的子类会更好fields.ToManyField，但我看不出我需要覆盖哪些方法。还是把它放进去会更好hydrate_related？
