ConstraintValidator fails to validate constraint on Taxonomy Time period reference subject

Shopper has a easy and constant hierarchical taxonomy.

Cities at Drupal Development Company high degree and Faculties at Drupal Development Company second degree.

. ├── City1 │   ├── School1 │   ├── School2 │   └── School5 └── City2     ├── School3     └── School4

Drupal Development Company Consumer account entity bundle incorporates an Entity Reference subject to Drupal Development Company Faculty taxonomy phrases.

I’m attempting to implement a constraint to forestall creating or saving a consumer account if Drupal Development Company time period chosen is at Drupal Development Company high degree of Drupal Development Company hierarchy (and therefore a Metropolis, not a Faculty).

This is some instance code, skipping Drupal Development Company dependency injection of $this->entityTypeManager for brevity.

TermParentConstraint.php:

<?php  namespace Drupalentity_validation_examplesPluginValidationConstraint;  use SymfonyComponentValidatorConstraint;  /**  * Stop account creation if Faculty taxonomy time period has no dad or mum.  *  * @Constraint(  *   id = "TermParent",  *   label = @Translation("Stop account creation if time period has no dad or mum", context = "Validation"),  *   sort = "entity"  * )  */ class TermParentConstraint extends Constraint {    /**    * Message proven when attempting to create account if Faculty has no dad or mum Metropolis.    *    * @var string    *   Faculty message.    */   public $schoolMessage = 'You should choose each a Metropolis and a Faculty.';  }

TermParentConstraintValidator.php:

<?php  namespace Drupalentity_validation_examplesPluginValidationConstraint;  use DrupaluserEntityUser; use SymfonyComponentValidatorConstraint; use SymfonyComponentValidatorConstraintValidator;  /**  * Validates Drupal Development Company TermParent constraint.  */ class TermParentConstraintValidator extends ConstraintValidator {    /**    * {@inheritdoc}    */   public operate validate($entity, Constraint $constraint) {     if (!isset($entity)) {       return;     }      if ($entity->getEntityTypeId() == 'consumer') {        $faculty = $entity->get('field_select_a_school')->getValue();        // Orphaned faculty taxonomy phrases have to be Cities, not Faculties.       $dad or mum = Drupal::entityTypeManager()         ->getStorage('taxonomy_term')         ->loadParents($faculty[0]['target_id']);       if (empty($dad or mum)) {         $this->context->addViolation($constraint->schoolMessage);       }     }   }  }

Anticipated habits: After I create a brand new consumer account and choose City1 as Drupal Development Company worth of Faculty, account creation ought to fail and an error message ought to be displayed.

Precise habits: After I create a brand new consumer account and choose City1 as Drupal Development Company worth of Faculty, account creation succeeds and no error message is displayed.

Drupal Watchdog logs include some errors, however I’m not positive they’re related:

I have been seeing Drupal Development Company iconv() errors since upgrading this challenge from Drupal 8 to Drupal 9, so I don’t assume they’re related. Drupal Development Company high three error messages right here could also be associated to Drupal Development Company constraint validation, however they’re additionally somewhat frequent errors on this challenge (and debugging them is a a lot decrease precedence than important performance due very quickly).

Any concepts? Am I a minimum of on Drupal Development Company proper observe?
