Почему не происходит запись данных из формы Django в базу данных?

Question

[PreFireSkills]

Не хочет записывать данные из формы в БД. При этом месседж приходит, что пост добавлен успешно. Вот мой код:
models.py

class Post(models.Model):
    STATUS_CHOICES = (
        ('unpublished', 'Unpublished'),
        ('published', 'Published'),
    )
    user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='posts_created', on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    slug = models.SlugField(max_length=200, blank=True)
    body = models.TextField(max_length=5000, null=False, blank=False)
    image = models.ImageField(upload_to='images/%Y/%m/%d/')
    created = models.DateField(auto_now_add=True, db_index=True)
    updated = models.DateTimeField(auto_now=True)
    status = models.CharField(max_length=11, choices=STATUS_CHOICES, default='unpublished')
    anonymity = models.SmallIntegerField()


    def __str__(self):
        return self.title


    def save(self, *args, **kwargs):
        if not self.slug:
            self.slug = slugify(self.title)
        super(Post, self).save(*args, **kwargs)

forms.py

class PostCreateForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ('title', 'body', 'image','anonymity')

views.py

@login_required
def post_create(request):
    if request.method == 'POST':
        post_form = PostCreateForm(instance=request.user, data=request.POST, files=request.FILES)
        if post_form.is_valid():
            cd = post_form.cleaned_data

            post_new = post_form.save(commit=False)

            #post.user = Profile.objects.get(user=request.user.id)
            post_new.user = request.user
            post_new.save()
            messages.success(request, 'Add post successfully')

        else:
            messages.error(request, 'Error add your post')
    else:
        post_form = PostCreateForm(instance=request.user)
    return render(request,
                  'posts/post/create.html',
                  {'section': 'posts',
                   'post_form': post_form})

Буду очень благодарен за помощь!
