end

Instance Method Details

#find_access_control_for(resource:) ⇒ Valkyrie::Resource

Wings needs special handling for this query, since ‘Hydra::AccessControl` relationship direction is inverted from the `Hyrax::AccessControl`. We need to query from the `access_control_id` stored on the resource, instead of doing an `inverse_references_by` lookup.

Parameters:

  • resource (Valkyrie::Resource) —

    find access control for this resource

Returns:

  • (Valkyrie::Resource) —

    the access control resource

Raises:

  • (Valkyrie::Persistence::ObjectNotFoundError)
