RelatedObjectDoesNotExist at /post/new/ - Post has no author - django

Question

I have implemented allauth for user registration and now I am trying to associate the current_user to a post when its being created. When I press 'Submit' I get 'Post has no author' clearly the posts don't recognize the user.
Model:
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
class Post(models.Model):
title = models.CharField(max_length=100)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.DO_NOTHING)
def __str__(self):
return self.title
View:
def create_post(request, pk=None):
form = PostForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.author(request.user)
post.save()
else:
form = PostForm()
context = {'form' : form}
return render(request, 'blog/create_post.html', context)
I could really use some pointers, many thanks.

You can set the author instance of the .instance wrapped in the form:
from django.contrib.auth.decorators import login_required
from django.shortcuts import redirect
#login_required
def create_post(request, pk=None):
if request.method == 'POST':
form = PostForm(request.POST)
if form.is_valid():
form.instance.author = request.user
form.save()
return redirect('name-of-a-view')
else:
form = PostForm()
context = {'form' : form}
return render(request, 'blog/create_post.html', context)
Note: You can limit views to a view to authenticated users with the
#login_required decorator [Django-doc].
Note: In case of a successful POST request, you should make a redirect
[Django-doc]
to implement the Post/Redirect/Get pattern [wiki].
This avoids that you make the same POST request when the user refreshes the
browser.
