Как я могу получить данные от указанного c пользователя django python

Question

Ошибка IntegrityError в / add-media / UNIQUE: сбой ограничения users_media.user_idUNIQUE: users_media.user_id Ошибка UNIQUE: users_media.user_id

Я пытаюсь получить данные от указанного пользователя c, но вместо этого я получаю все данные от всех пользователей в базе данных.

views.py

@login_required
def profile(request):

    if request.method == 'GET':        
        media_images = Media.objects.all()

    context = {
        'media_images':media_images,  

    }
    return render(request, 'users/profile.html', context)

@login_required
def add_media(request):

    if request.method == 'POST':
        form = MediaForm(request.POST, request.FILES)
        if form.is_valid():
            form.instance.user= request.user

            form.save()
            return redirect('http://127.0.0.1:8000/')
    else:
        form = MediaForm()

    return render(request, 'users/add_media.html', {'form':form})

models.py

class Media(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
    image_name = models.CharField(max_length=50)
    image_description = models.CharField(max_length=80)
    image_image = models.ImageField(upload_to='media', default='default.jpg')

    def __str__(self):
        return f'{self.user.username} Media'

Вы фильтруете файлы так, что user ссылается на request.user:

@login_required
def profile(request):
    media_images = Media.objects<b>.filter(user=request.user)</b>
    context = {
        'media_images':media_images,  
    }
    return render(request, 'users/profile.html', context)
