controller_admin_referrers
Shows the list of pages (resources) which refer to this resource through an edge.
The required id path argument can be a resource id or name. The controller
requires permission to use mod_admin, renders admin_referrers.tpl, and
passes the resolved resource as id. It also honors Zotonic's gone-resource
redirect when the requested resource was replaced.
Use {% url admin_referrers id=id %} to construct its URL.
