A display's DHCP IP can change; its FQDN (F<serial>.<domain>, domain from the
display_fqdn_domain setting) is stable and the collector already reports the
serial. Add a nullable unique fqdn column (varchar191 so the index fits utf8mb4
without innodb_large_prefix), make ipaddress nullable, and require fqdn OR ip.
visitor-location + display-role resolve by FQDN first, then IP; create/update
accept fqdn. Core migration 7d31, verified up/down/idempotent on MySQL 5.6.
'Business unit' wording -> 'location' in the validation messages.
One 'display' image resolves what it shows from its own IP, like the existing
visitor-location BU mapping. Extend DashboardDefault with displayrole
(dashboard|lobby|partskiosk; migration 7d28, businessunitid now nullable since
only the dashboard role needs one) + a role->path map. New unauthenticated
GET /api/dashboarddefaults/display-role returns {role, path, businessunitid}
for the caller IP. Settings UI gains a Display selector, showing the business
unit only for the dashboard role.
Classic feature gap: a shopfloor/lobby kiosk auto-selects which business unit to
show based on the display PC's IP (classic dashboarddefaults table +
apivisitorlocation.asp). For the main admin dashboard this does nothing - it is
kiosk/visitor-display infra.
- Model: DashboardDefault (dashboarddefaults: ipaddress unique, businessunitid
FK, description). Migration 7d01_dashboarddefaults (head).
- API (core, /api/dashboarddefaults): CRUD + GET /visitor-location that resolves
the calling display's business unit from its IP (X-Forwarded-For/remote_addr,
or explicit ?ipaddress=); unmapped IP returns a null businessunitid, not an
error. Unauthenticated resolve (kiosks); writes are admin.
- Frontend: ShopfloorDashboard auto-selects its business unit via visitor-location
on load when none is chosen; Settings > Dashboard Defaults CRUD page +
dashboardDefaultsApi client.
Tests: create + resolve by IP -> BU; unmapped IP -> null; duplicate IP 409.
191 tests pass, naming green, app boots, endpoint + admin page verified live.
