Module: Hyrax::RedirectToDisplayUrl

Extended by:

ActiveSupport::Concern

Included in:

CollectionsControllerBehavior, WorksControllerBehavior

Defined in:

app/controllers/concerns/hyrax/redirect_to_display_url.rb

Overview

Controller concern that sends visitors who land on a path with a redirect-table row pointing elsewhere to that other path. Included on work and collection show controllers via the curation-concerns behavior modules.

Two request shapes hit this concern:

• Direct UUID URL visits (/concern/generic_works/<uuid>) — Rails routes natively to the show action. If the resource has a display alias, the row keyed on the UUID URL has to_path pointing at the alias, and the before_action 301s the visitor there.
• In-process dispatches from Hyrax::RedirectsController — the resolver finds a display-URL row and re-dispatches the request through recognize_path + controller.dispatch. To avoid the before_action firing again on the same logical request, the resolver sets request.env['hyrax.redirects.dispatched'] = true before dispatching; this concern checks the same env key and no-ops when set.
