Entity Reference Count is a field type that will count and display the number of
references to a particular entity.
Say you have two content types: 'Clinic' and 'Doctor'. Doctor has an entity
reference field referencing Clinic (i.e. a doctor works at a clinic, and
therefore a clinic can have one-or-more doctors). When you add an 'Entity
Reference Count' field to Clinic and configure it to count references from the
Doctor content type, you will be able to see how many doctors a clinic has when
viewing the node. Whenever the Clinic or any of the Doctor nodes are added,
updated or deleted, the count field will also be updated.
Installation
-
Install this module using the official Backdrop CMS instructions at
https://docs.backdropcms.org/documentation/extend-with-modules. -
Be sure you have at least one entity reference field configured, then add an
'entity reference count' field to the entity type that is referenced by the
entity reference field. Check the boxes for the entity reference fields that
should be counted. -
You will need to re-save any existing entities (or their referencing entities)
in order to update the count, otherwise it will be empty. -
NOTE: The module only works with entity reference fields which use the "Simple
(with optional filter by bundle)" mode. The "Views: filter by an entity
reference view" mode will not work.
