GCS links expire

[daedric]

Hi folks, I'm using django-summernote with a storage using the unified ACL. The generated links eventually expire so the images end up not being displayable.

To workaround the issue I've written a filter:

from urllib.parse import urlparse
import pathlib

from django import template
from django.core.files.storage import DefaultStorage
from bs4 import BeautifulSoup
from django.conf import settings
from django.template.defaultfilters import stringfilter

register = template.Library()
storage = DefaultStorage()
root = pathlib.Path("/", settings.GS_BUCKET_NAME)


def process_url(url_raw):
    url = urlparse(url_raw)
    if url.netloc != "storage.googleapis.com":
        return url_raw

    return storage.url(str(pathlib.Path(url.path).relative_to(root)))


@register.filter("refresh_images")
@stringfilter
def refresh_images(source):
    soup = BeautifulSoup(source)
    for img in soup.findChildren("img"):
        url = img.attrs["src"]
        img.attrs["src"] = process_url(url)
    return str(soup)

I am not too happy with this solution and was wondering if you had a suggestion?

Cheers,
