[SOLVED] CB Gallery Module - Cached random order?

I've got the module working to show 7 random gallery images from profile.%, but the images do not change unless I change the Limit on the Media tab in the module setting. It seems to generate a new random selection only when it's saved with new settings.



Is there a cache?

Version 2.0.1

Yes, the random order value is cached per gallery. There's already a feature ticket to review improving this.

One thing I've done is cache the directory build/database call every 15 minutes into a stored array, then use array_rand(), shuffle($array) or array[rand(0,count($array)-1)] to pick a key until the cache expires. You aren't reading the disk or database every time, but get pretty decent random display. Creating an item in the gallery could trigger the array cache, even. Just some ideas. At least I'm not crazy thinking it was misconfigured. Thanks!

The galleries are cached into session and pass from page to page using the gallery id generated from the galleries parameters. The random value is basically just the id. The big issue is it needs to have the same random seed when moving from Page 1 to Page 2 for example (otherwise paging literally can't work with random usage). This means it needs to cache with the gallery or be passed with the pagination link. Passing with pagination link only means when you edit an entry and hit cancel it returns to the wrong seed if you're on page 1 since it'll generate a new seed. This means return URLs then need to have it. It was easier to just cache it with the gallery initially and improve it later.

To show 1 random image (from users' uploads) in a module, I went to module's settings , and set Media \ Paging \ OrderBy to `random`.
In the `Gallery` tab there, I've set `asset` option to `profile.%`. Done!
Just stating this for anyone who might be stuck on this.

Yes, random now works because of a fix krileon put in forge.joomlapolis.com/issues/6250 six months ago.
