Query condition on entity reference field count

Question

I need to query an article with more than 1 tag (a field entity reference) in drupal entity query.

I tried this :

$query = Drupal::entityQuery('node')
                ->condition('type', 'article')
                ->condition('field_tags', 1, '>');
dd($query->execute());

But I got more than expected the articles id's and I don't why.

What is the good query to do that ?

Answer 1

Try to use the delta. This is explained here: QueryInterface:

$query = Drupal::entityQuery('node')
            ->condition('type', 'article')
            ->condition('field_tags.%delta', 1, '>');
dd($query->execute());
