Selecting specific fields using select_related in Django

Question

I have two models Article and Blog related using a foreign key. I want to select only blog name while extracting the article.

articles = Articles.objects.all         


        

Answer 1

select_related should be use on the whole model, and then you can filter it more. This will work:

Articles.objects.select_related('blog').only('blog__name', 'title', 'create_time')
