ValidReferenceConstraintValidator should not try to enforce data integrity on pre-existing references

Problem:

Nodes are not saving with inaccesible pre-existing referenced items.

Issue has been fixed once with the ticket: https://www.drupal.org/project/drupal/issues/2791269 → stating, "Allow saving pre-existing references to inaccessible items" means there should not be any validation check for the existing referenced items.

Still the node save was disallowed and throwing an exception : "This entity (node: 32) cannot be referenced."

On cheking deeper the solution contains a condition:

/core/lib/Drupal/Core/Entity/Plugin/Validation/Constraint/ValidReferenceConstraintValidator.php
@@ -119,32 +119,31 @@ public function validate($value, Constraint $constraint) {
+          // Check if any of the invalid existing references are simply not
+          // accessible by the user, in which case they need to be excluded from
+          // validation
+          if (isset($previously_referenced_ids[$target_id]) && isset($existing_entities[$target_id]) && !$existing_entities[$target_id]->access('view')) {
+            continue;
+          }

Accordingly, the clause !$existing_entities[$target_id]->access('view') is causing problem in my casue.

Steps to reproduce

  • Create a content type with an entity reference field, able to reference the same content type.
  • Give a test user access to edit all content of that type + "view own unpublished content".
  • Create an unpublished node using user "test user".
  • Create another node referencing the unpublished node. using user "test user"
  • As the test user, edit the second node. Notice the reference field says “- Restricted access - (1)”
  • Try saving the node, get an “This entity (node: 1) cannot be referenced.” error.

here, the condition is failing becasue the "test user" has "view access" for the referenced unpublished node ceated by himself.

It is not only the problem with "view own unpublished content" permisisons. When you have any other Node access module enabled like Domain Access or content modertion. The issue get more severe and requires a broader scope.

Becasue user will be editing a node shared on different domains consisting different doamins (assigned) entity references.

Required solutions

  1. The scope of the validation check should be defined.
    • When the items should be validated - pre-existing or new ?
    • Should validate existing items in case of deleted entites ?
    • What is overall requirement of the validations ?
  2. Remove the "view access" condition ? And add other conditions depending upon the anwser of above point.

    I'm in Drupal 10.3.1 using Mercury Editor, Layout Paragraphs and Paragraphs.

    We are getting the following error when editing a node with the above setup with a particular paragraph type which is referencing an image (the image is not using a view to render - it is default).

    This entity (paragraph: [paragraph id #]) cannot be referenced.

    I found initially that I could clone the entity, delete the original, and then save the node. However, on the next edit the issue still remained.

    I tried the patch from 39 and could not apply it.

    I tried the patch from 38 and it addressed my specific issue.

    Rerolled #38 for 10.3.x branch (it also applies to 11.x). There's something not quite right in #40 it's missing a variable name. I couldn't reproduce the TypeError either. I'll push this to an MR for 11.x as well.

    There is an additional problem here - if we're working with TRANSLATED entities, the existing entity IDs need to be added from all the translations, otherwise the integrity violation still gets triggered. I've added another patch (apologies - haven't figured out how to contribute to an existing PR yet).
