We are using Django for our website. I have a query for model User and I want to exclude users which have two identical fields – in this case id and username. So if the id==username, I want to exclude them. How do I do it?
The query looks like:
users = User.objects.filter(...)
And I want to add .exclude(...) where the id and username fields are equal.
>Solution :
You can refer to a field with an F expression [Django-doc], so:
from django.db.models import F
users = User.objects.exclude(id=F('username'))
