I'd like to setup two content types in a parent -> child relationship.
Node A of content type "parent" has custom field:
Node B of content type "child" has custom field:
When the description of Node A changes, Node B automatically reflects this change.
I'd like to achieve this entirely on the backend, no UI or forms needed.
I will be creating the child nodes programmatically.
Topics I've found have danced around what I'm trying to do but lack the details I need to execute it. inheriting fields from a base content type
I have experience with Drupal 6 & 7 but am new to Drupal 8's entity apis.
A detailed explanation or example of how to achieve this would be greatly appreciated.
