Constant Summary collapse

LockKeyPrepopulator =

This constant is part of a private API. You should avoid using this constant if possible, as it may be removed or be changed in the future.

Note:

includes special handling for Wings, to support compatibility with ‘etag`-driven, application-side lock checks. for non-wings adapters we want to move away from application side lock validation and rely on the adapter/database features instead.

proc do |_options|
  if Hyrax.config.disable_wings || !Hyrax.metadata_adapter.is_a?(Wings::Valkyrie::MetadataAdapter)
    Hyrax.logger.info "trying to prepopulate a lock token for " \
                      "#{self.class.inspect}, but optimistic locking isn't " \
                      "supported for the configured adapter: #{Hyrax.metadata_adapter.class}"
    self.version = ''
  else
    self.version =
      model.persisted? ? Wings::ActiveFedoraConverter.convert(resource: model).etag : ''
