Question

I have 2 models:

Pages
------------
Page    User
S500    John
Gimp    John
WoW     John

Subscriptions
------------
Page    User 
S500    John

So Page field in Subs model is an FK to Pages model. I am trying to return a queryset that will display all the pages belonging to John that doesn’t have a subscription belonging to him.

I tried something like:

fbpages = Page.objects.filter(user='John').exclude(id__in=[Page.id for Page in Page.subscriptions.filter(Page=Page)])

I think I’m close but I’m not sure where I’m going wrong with that query.

I did something like:

current_subs = Subscriptions.objects.filter(user='John')
pages = Page.objects.filter(user='John').exclude(id__in=[subs.Page.id for subs in current_subs])

which works but how do I combine it into 1 query?

Answer 1

pages = Page.objects.filter(user='John').exclude(subscriptions__user="John")
