Re: QuerySet for related models

Hello Todor,

I followed your directions and used https://docs.djangoproject.com/ja/1.9/ref/contrib/contenttypes/ for reference but I got stuck at error 'GenericForeignKey' object has not attribute 'get_lookup'. I tried Product.objects.aggregate(Count('hits'))[:6]. In my models.py I got following code:

hits = GenericRelation(HitCount, content_type_field='content_object', object_id_field='object_pk',)

    class Meta:

        ordering = ["-title"]

Removed the -hits from ordering section and rest of the code is same. I searched it on google but it showed some Django based bugs.

Any suggestions?

Thanks,

Honestly, I don't understand that.

The HitCount class already has a GenericForeignKey, maybe you are looking for a Reverse Generic Relation class in order to get the Hits for a product.
