https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42790 --- Comment #4 from Martin Renvoize (ashimema) <martin.renvoize@openfifth.co.uk> --- Created attachment 201558 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=201558&action=edit Bug 42790: Add booking-aware Extend action for issued bookings This patch adds an Extend action to the bookings tables for issued bookings, visible to users with the circulate permission on both the patron bookings tab and the biblio bookings page. The button opens a new modal showing the current booking end date and the current checkout due date, with a flatpickr date picker that: * blocks the date ranges of any other new or issued booking for the same item * caps the maximum selectable date at the day before the earliest subsequent booking starts On confirm, the extension is performed as a staff authorised renewal of the linked checkout - a single call to POST /api/v1/checkouts/{checkout_id}/renewal with the requested due_date and the renewal_limit override. The server validates the date against bookings for the item and keeps booking.end_date in sync with the renewed due date. Errors (clash with the next booking, renewal limits with overrides disabled) are displayed inside the modal without closing it, so staff can pick an earlier date. The Extend button only renders when the booking has a linked checkout to renew. Test plan: 1) Create a booking, check the item out to the patron (booking becomes issued) and confirm the Extend button appears on both the patron bookings tab and the biblio bookings page 2) Click Extend; confirm the modal shows the current end date and the checkout due date 3) Create a subsequent booking for the same item; re-open the modal and confirm its dates are blocked in the picker and dates beyond its start cannot be selected 4) Select a valid new date and confirm; verify both the booking end_date and the checkout due date are updated 5) Confirm the checkout now shows a renewal in its renewal history -- You are receiving this mail because: You are watching all bug changes.
