Answer 1

AssociationField has a method called setQueryBuilder which help you modify the query.

In your case, your association field should look like:

AssociationField::new('chapters')
            ->setQueryBuilder(function ($queryBuilder) {
                return $queryBuilder->andWhere(''); // your query

            });

You could also use a repository and call its method but returning a query builder (and not the result) inside setQueryBuilder.
