Delete image from storage when removing image within the widget

[Marchamp]

I was wondering if it is possible to delete images from storage when they are removed within the summernote widget.
Whenever an image is dragged into the widget, it would automatically be uploaded even before 'save'.

I tried using django-cleanup but it only works on FileField and ImageField.

Is 'delete from storage' feature built into django-summernote?
If so, how may I proceed?

I guess workaround solution would be to upload images as ImageField and use the image in the widget as img src url after upload.
Thanks.

I wish this feature be added too.
This is very helpful when a lot of objects with rich-text are added and removed frequently. If the image cannot be deleted with field in cascade, many unused files will remain on the server.
The difficulty of this feature is, currently SummernoteTextField is just a models.TextField with html code and images are display with url, no additional information about images is recorded outside the rich-text.

My tentative suggestion of 2 solution:

1. Create a totally self-defined field extends from Field rather than TextField or CharField
2. Append the file id or url to the end of the html code (one file per line) and making it a kind of new "format". Strip those when display

That would be a cool feature to have.

i'm do it by that demo way

import os

from django.dispatch import receiver
from django.db.models.signals import post_delete

from mindkeeper.settings import MEDIA_ROOT, MEDIA_URL
from .models import Cards


@receiver(post_delete, sender=Cards)
def on_delete(sender, **kwargs):
    images = []
    html_str = kwargs['instance'].content

    while "img" in html_str:
        left_enter = html_str.find('<img')
        html_str = html_str[left_enter:]
        right_enter = html_str.find('>') + 1
        images.append(html_str[:right_enter])
        html_str = html_str[right_enter:]

    for image in images:
        left_enter = image.find(MEDIA_URL)
        image = image[left_enter + len(MEDIA_URL):]
        right_enter = image.find('"')
        path = os.path.join(MEDIA_ROOT / image[:right_enter])
        os.remove(os.path.join(path))

where Cards it's something like post in blog
