this seems correct but you already this user you are using doesn't have profile so here my notes :

You can use get_object_or_404 this if profile not found will return not found

from django.shortcuts import  get_object_or_404
form.authore =  get_object_or_404(Profile, user=request.user)

when user-created no logic here profile must created so it is logical user doesn't have profile

it is better to use one_to_one relation ship when creating user profile as each user has only one profile and vice versa

to make it correct working refer here https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

go to Extending User Model Using a One-To-One Link in previous link

field execute this tutorial and user profile will created auto when user created
