Sub-subfolder displayed but does not open

Hi!

I’m setting up pigallery2 for the first time on my Raspberry Pi 3B. I’m using the docker image without nginx, but with pigallery2 as a subdirectory of my Apache vhost for Nextcloud (using ProyPass etc.), so that my Nextcloud is reachable on https://subdomain.domain.com and Pigallery2 on https://subdomain.domain.com/photos . I struggled a bit to get it to use the pictures from Nextcloud but managed using symlinks to my storage disk /app/data/images/user -> /mnt/raid1/clouddata/user/files/gallery by adding a volume /mnt/raid1/clouddata:/mnt/raid1/clouddata:ro into docker-compose.yml. So far so good, but the background may be relevant to my problem.

Now, whether I create a sub-subfolder inside the images folder in the symlink’d Nextcloud folder or directly manually in the images folder, I can index and visualize the pictures in the main and in the first subfolder, but clicking on the sub-subfolder brings me back to the main images folder. Is this an expected limitation of pigallery2 or a real bug?

Docker-compose excerpt:

...
volumes:
      - "/mnt/raid1/pigallery2/config:/app/data/config"
      - "db-data:/app/data/db"
      - "/mnt/raid1/pigallery2/images:/app/data/images:ro"
      - "/mnt/raid1/pigallery2/tmp:/app/data/tmp"
# clouddata for symbolic links:
      - "/mnt/raid1/clouddata:/mnt/raid1/clouddata:ro"

Web app: In the web app, I can see the folders images/simon and images/simon/Albumtest1 and their thumbnail, as well as the pictures in images/ and in images/simon/, but not in Albumtest1.

Thanks for the example GPX file! I’ve put that one in the album folders, it’s unfortunately not displayed either on the gallery page, both on my laptop and on the rpi (both with the nightly docker image).

Can you try logging in, then opening in a separate browser https:///photos/api/gallery/content/subfolder1/subsubfolder (so not with%2 but with / ) and see what happens.

Navigating to the subsubfolder on my local instance shows the URL http://localhost:81/gallery/subfolder%2Fsubsubfolder in my browser, however pointing the browser directly at http://localhost:81/gallery/subfolder/subsubfolder just brings up pigallery2’s loading and welcome page. On the rpi, opening the URL https://<mydomain>/photos/gallery/subfolder1/subsubfolder does the same (loading and welcome page), but https://<mydomain>/photos/gallery/subfolder1%2Fsubsubfolder brings error 404 (like the console was saying). Instead of permissions (my current image/ folder structure is all in the same local folder, not a single symbolic link) I looked into Apache’s rules to somehow decode this %2F, and following this thread I added the following to my apache config:

AllowEncodedSlashes NoDecode
# Pigallery2 docker container exposes to port 1234
ProxyPass        http://localhost:1234 nocanon

Aaand voilà, the sub-subfolder issue is resolved! I hope that this post helps other people someday 😃

The GPX issue is however not due to Apache since it’s also failing using the pre-containerized Nginx proxy.

I do not mind adding this. A separate feature request would be great. Better would be a pull request 😃 (I dont have that much time for this project)
