Django Media file auto-delete

Question

When I upload an image through Django administrator and I delete the image file again, why does it not delete the image int the /media directory?

When I delete an image file, I want it to delete the image automatically even from the directory, not only the model instance.

My model:

class ImageForExtractText(models.Model):
    image = models.FileField()

And settings:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static")

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "media")

What should I do to make it happen, when deleting the image file from Django administration? It should be deleted from both Django administration and the media directory.

Django doesn't delete the files on delete.

You can add a signal to delete the file:

from django.db.models.signals import pre_delete
from django.dispatch.dispatcher import receiver

class ImageForExtractText(models.Model):
    image = models.FileField()

@receiver(pre_delete, sender=ImageForExtractText)
def delete_image(sender, instance, **kwargs):
    # Pass false so FileField doesn't save the model.
    if instance.image:
        instance.image.delete(False)
