Hello im new to django and this is my model and I have 2 tables "auth_user" table and "blog_post" table. Inside blog_post table I have a column called "author_id" which is the foreign key between "blog_post" table and "auth_user" table. The question is how can i get all posts from "blog_post" table when foreign key = 1 or 2 or 3 or.. etc. Thanks before hand.

If you meant that you wanted to filter by the author, then what you can do is provide the author_id as a query parameter on your request, and have the view serving the request filter by the author.

Post.objects.filter(author_id=author_id)
