I am refactoring a D6 site into D8.
Two of the entities (content types) I have are Event and Document. There is a 1:n relationship between Event and Documents.
I added 'For Event' field on Document as an entity reference field to the entity Event. Works fine. Documents have a reference to an Event.
Now on the Event display I need to show a list of all referencing Documents (linking to them).
In D6 this was accomplished through two modules, Node Reference and Node Referrer.
I've lost the plot for finding the equivalent for this for D8.
Can anyone give me a clue on how to get a list of referring entities on an entity display?
