Querying For Followers In News-feed-based Data Model In Django
I have this following (simplified) model in Django which is very similar to the Pinterest data model: class UserProfile(models.Model): user = models.OneToOneField(User) class
Solution 1:
The first would be something like this I think:
User.objects.filter(collection_owner__owner='the user')
The latter should be something like this:
Item.objects.filter(collections__followers='the user').distinct()
You should be aware however that these type of queries do not scale to large amounts of data. Doing that will require quite a bit of hacking...
