Delete image from media when object is deleted

Question

When I delete an object from my database, the image previously uploaded stays in the media directory. I would like to delete it automatically.

Here is my model:

class Door(models.Model) :
    image = models.ImageField(upload_to=upload_location)
    color = models.ForeignKey(Color, on_delete=models.CASCADE)
    price = models.DecimalField(max_digits=10, decimal_places=2, default='119.99')

Here is my delete view:

def door_delete(request, door_id) :
    door = get_object_or_404(Door, id=door_id)
    door.delete()
    return redirect("/dashboard/doors")

I have tried to instert before door.delete() line door.image.delete() but that hasn't worked out as far I as know.

Please help me if you know the answer.

A possible scenario: two `Door`s have the *same* `image`. So it is quite unsafe to simply delete the file. — Willem Van Onsem, Jul 31 '18 at 09:30
I would advice *not* to do this at the `.delete()` function (it is furthermore sometimes possible to *bypass* functions like `.save()` and `.delete()` anyway). But write a command that occasionaly checks what media is no longer used, and removes these. — Willem Van Onsem, Jul 31 '18 at 09:34
I did exactly what the post suggested but that didn't solve anything. — Fantasmo Clone27, Jul 31 '18 at 09:36

do as below,

def door_delete(request, door_id):
    door = get_object_or_404(Door, id=door_id)
    if door.image:
        door.image.delete()
    door.delete()
    return redirect("/dashboard/doors")
