django form is not picking data which is already in database - django

Question

How do I update my form as the
form.instance.users = request.user
is not working however if I print request.user on terminal it prints the username of the user currently logged in.
Also in this form I want to pick existing data from that user to display in the form to update it.
The save form button return HttpResponse saved successfully but the data is not stored in the database.
