How can I find the union of two Django querysets

0 votes
I’ve got a Django model with two custom manager methods. Each returns a different subset of the model’s objects, based on a different property of the object.

Is there any way to get a queryset, or just a list of objects, that’s the union of the querysets returned by each manager method?

Hello @kartik,

Try this:

records = query1 | query2

If you don't want duplicates, then you will need to append .distinct():

records = (query1 | query2).distinct()

Hope this is helpful!!

Thank You!
