Problem/Motivation

Using default-content:export-references does not export comments.

Steps to reproduce

  1. Create a content type that allows comments
  2. Create a node of the type
  3. Place a comment on the node
  4. Export the node using drush dcer
  5. Notice that the comment is not automatically exported

Proposed resolution

Add support for comments.

Remaining tasks

  • Decide whether to treat comments as compound entities and export within the parent entity, or as stand-alone entities
  • Create a patch
  • Review
  • Commit

Comments are clearly standalone, and the node has no reference to comments, its comments that reference the parent node in a custom DER-like, two-field based reference. The comment field just stores the comment setting and I don't think it's a good match to embed them.

Supporting that lookup in either direction would require comment-specific logic. Open to that as I suspect right now, the comment parent reference isn't properly referenced.

this already seems to be half-working at least, entity_id does contain the entity UUID. not sure if there's anything to do here.

When working with forum comments at least, we get this error:

TypeError: Drupal\forum\ForumIndexStorage::updateIndex(): Argument #1 ($node) must be of type Drupal\node\NodeInterface, null given, called in /var/www/html/web/core/modules/forum/forum.module on line 287 in /var/www/html/web/core/modules/forum/src/ForumIndexStorage.php on line 93 #0 /var/www/html/web/core/modules/forum/forum.module(287): Drupal\forum\ForumIndexStorage->updateIndex(NULL)

That suggests that the entity_id mapping isn't loading properly.

What that probably means is that the reference is there, but not tracked as a dependency, so default_content doesn't know that it needs to create the node before the comments.
