Question

I have a query in Django that is resulting in unique rows but some contain common values in various fields. I want to consolidate those rows with the common values.
Example:
Assume each row returns an id, library, book title, author, and publication date.
I only want to know only about the book title, author and publication date. Additionally, I would like to know about 1 and only one library where it can be found. How so using Django?

Answer 1

Could you try this:

Books.objects.all().only('title', 'author', 'date').extra(where=['library IS NOT NULL']).distinct()
