I have 3 Entities : Country, Region, City A region has a country property, and the city had a region property. In the city crud controller, I'd like to add a filter by country. I try to do
return $filters
->add('region.country')
But I have this error : Call to a member function getAsDto() on array
And I also try to add a getCountry in my City entity, which return region.getCountry value, and then do
return $filters
->add(EntityFilter::new('country'))
But I have this error : An error has occurred resolving the options of the form "Symfony\Bridge\Doctrine\Form\Type\EntityType": The required option "class" is missing.
Is there a simple way to do a filter on a parent of an object in my entity ?
