[Answer]-Add value to database without using forms in django

get the article instance first, commit explained in docs

article = form.save(commit=False)

then assign the author

article.Author = request.user 

creating an Author field will automatically create an Author_id field in your table. I think if you create your field named Author_id it could create an Author_Id_id field? It’s safer in some ways to work with objects ie ‘User’ instance then it is to work with integers ie user.id

article.save()
