Bug Description

It would be useful to have the contents of a carousel have a definite and configurable ordering for display purposes. This would enable several use cases:

- new item carousels that display the newest items first
- manually-organized carousels where the position of a title in the carousel's bucket matched the position that the title would display in the carousel

I think it would be useful to have an option to set a specific order for records - such as Galen specified, or even for things like series in series order - but ALSO to have an option for dynamic changing order.

I have a carousel that has 60+ titles, I would love if the order were not static so that different titles appear in the first few slots on opening the opac home.

I've added a commit to make use of the already-calculated ordering data at the display level. I did not address the "random order" request, as that's definitely a new feature, but I think the basic predictable ordering issue is 100% bug fix.


And, from the commit message:

Previous to this commit, the item display order for carousels was undefined. Now, ordering is stable and predictable.

For Newly Cataloged Item and Newest Items by Shelving Location carousels, the order is from most recently cataloged to least recently cataloged.

For Recently Returned Item carousels, the order is from most recently returned to least recently returned.

For Top Circulated Items carousels, the order is from most circulated to least circulated.

For Manual carousels (as of now, without the ability to adjust the Position of items) it is the order they are added to the backing bucket. Thus emptying and refilling the bucket allows reordering.

Since Mike's patch addresses part of the original bug I've split off the other two pieces of this report. See bug 1911938 for manual reordering and bug 1911940 for random ordering.

I tested all four types of carousels and it works great! (And I did +1 to the option to randomize ordering on bug 1911940.) My sign off is at:;a=shortlog;h=refs/heads/user/mccanna/lp1866406-carousel-item-order-signoff
