isReferenced( )

Checks if a reference to the referenced item exists in the specified property of the referring item.

The isReferenced() function returns a Promise that resolves to true if the referring item contains a reference to the referenced item in the specified property. The Promise is rejected if the current user does not have read permissions for the collection.

Calling the isReferenced() function does not trigger any hooks.
