[Enhancement]: Random library sorting

[gavinorland]

Describe the Feature/Enhancement

For this issue you introduced the "Discover" feature. Thanks! I think it would still be good, though, if there was a "Randomly" option available for the library sorting menu as well (as I think Plex has, for example).

Why would this be helpful?

This would enable us to see audiobooks we haven't seen for some time, helping us to choose which to play.

Future Implementation (Screenshot)

"Randomly" option would be among the existing options shown in the screenshot.

Audiobookshelf Server Version

2.11.0

This is something that the Plex media server even uses....

@advplyr Many thanks for adding this - and so quickly.

[ZLoth]

Thank you!

Fixed in v2.12.0.

@advplyr Just trying this out (thanks again). It seems to give two different randomised orders when "toggled", but these two never change, even on page refresh. Is that the intended functionality? I thought perhaps it might randomise the view every time that option is selected.

[advplyr]

All of the library API requests are cached for 30 minutes.

The caching system setup right now is very basic. The cache gets cleared if any of the items are updated. This will be improved eventually to only clear what is necessary.

That specific request could probably be setup to skip the cache.

[advplyr]

I was wrong about the cache. The 30 minute cache is only applied to the home page shelves. Otherwise the cache remains until something in the database changes.

I made the update so that random sort skips the cache. That makes sense.
Here is the issue for that #3249

Sounds great, thanks. btw I guess to enable this sorting in the app (as well as in the web UI) a task or issue would need raising in the other repo.
