Help with collections

[zikkrin]

I cannot get new movies automatically added to a preexisting collection, though I'm not sure if this an issue or a result of unclear wording. I have a movies library, and in the administration page I checked this box: "Automatically add to collection: When at least 2 movies have the same collection name, they will be automatically added to the collection". This works; however, I would also expect that new movies added with the same collection name as a preexisting collection would be automatically added to the collection. For instance, if I add the first 4 Harry Potter movies and ask Jellyfin to scan the library, it determines they all belong to the same collection and adds all 4 to the Harry Potter collection. If I then add the 5th movie and scan the library, Jellyfin won't add this new movie to the collection even if it determines the new movie is part of the same box set ID as the previous 4. Am I misunderstanding this setting? Regardless, is there a way to get the functionality I want without manually adding all the movies?

This should work, but is all based on metadata. If you add a movie, it needs to have the exact same collection name in order to be added to the same collection. If you're relying on disparate sources or Jellyfin's scraping capabilities you might be disappointed. I would point you toward examining the metadata of a couple of the films that are already in the collection -- specifically TMDB Box Set ID (I'm sort of guessing here, but this is the only ID that corresponds to "collection" I can find which matches in my collections).

My guess is that the odd film out doesn't share the same box set ID and thus doesn't qualify to be added to the collection automatically. You might be able to fix by refreshing the metadata on the film.

EDIT: You can also try the plugin that helps with this, but I'm unsure what using both the built-in setting and this plugin will result in...play around at your own risk: https://github.com/jellyfin/jellyfin-plugin-tmdbboxsets.

Thanks for the reply! So the puzzling thing to me is that every instance I've noticed this problem, the newly added movie has the same TMDb box set ID as the previously added movies, which is unsurprisingly the same box set ID as the collection. They just don't get added, even when I refresh metadata on the library. However, I tried your suggestion to refresh metadata on the movie itself and it immediately added it to the collection. So I'm not really sure what's up, but this is better than manually adding to a collection. I wish it was fully automatic though...

Sounds like something might not be firing in the background. Have you checked your logs? That should get picked up by an automated process, but I'm not sure which task. Look at your scheduled tasks, see about when they run, and scan your logs to see if there are warnings or errors that might key you in on if there's an issue that could be causing these to not get added. If it's a new occurrence, there might be a new problem with your setup, config, or even a bug that has been introduced. Keep an eye on it. I haven't noticed, but my attention has also been elsewhere. When I get a moment I'll see if I can recreate...

I'm still fairly new to JF... where could I find my logs? I'm using the official Docker image. Also, any luck recreating this yourself? I hope the issue isn't with my setup, as I basically just booted up the container and pointed the movies library to a folder. I don't think I've done any specialized setup.
