My website works perfectly fine with django-markdownx, unless I upload images.
When I drag and drop image on markdownx form, auto generated image url is added in form like below:
As you see, image is shown just fine. My storage is AWS s3, and I'm using private bucket.
The problem occurs, however, an hour later. In the markdown url query parameter X-Amz-Expires=3600, which is an hour. So after that the url is no longer valid, saying request has expired.
This is another expired url, but you get the idea.
I use django-storages, boto3, AWS S3 for file storages. According to django-storages doc,
AWS_QUERYSTRING_EXPIRE (optional; default is 3600 seconds)
The number of seconds that a generated URL is valid for.
I might extend expiry time like super long as suggested in other post in SO, but doesn't that mean I should update at least once every super long time period? That doesn't seem the right way.
Some suggested making S3 bucket public, but I don't want allow anyone to download my image.
I delved in django-markdownx doc and github, without making much progress.
How can I get dynamically made presigned url when uploading image using djang-markdownx? Let me know if I'm missing anything or any suggestion is welcome.
