django_program.registration.views_checkin

Staff-facing JSON API views for on-site check-in and product redemption.

These views power the scanner UI used by registration desk volunteers. All endpoints require staff or superuser authentication and are scoped to a conference via the conference_slug URL kwarg. The scanner UI is responsible for including the CSRF token in POST requests.

Classes

LookupView	Look up an attendee by access code without performing check-in.
OfflinePreloadView	Bulk export attendee data for offline scanner fallback.
RedeemView	Redeem a purchased product (order line item) for an attendee.
ScanView	Scan an attendee's access code and perform check-in.
StaffRequiredMixin	Require staff or superuser access for check-in API views.
