Sylius EntityFilter choice from a part of resources - symfony

Question

I used a Sylius 1.0.0-beta1 and ported EntityFilter from dev-master due to lack of this functionality in last stable version. Everything works fine but is there any way of choosing not from all resources but only from part of them?
I need to make a filter based on Taxonomies. I have a few taxons which are city names and all of them have parent taxon called City (code: city). So I want to display in that filter all children of city taxon.
My grid configuration is shown below:
sylius_grid:
grids:
smartbyte_admin_products_by_event_archetype:
...
filters:
...
taxon:
type: app_entity
options:
fields: [taxon.id]
class: "%sylius.model.taxon.class%"
city:
type: app_taxon
The first filter from configuration works and filters fine, except it takes all taxons, but I need to show only some.
I tried also make my own filter (the second one) but I get a text field instead of entity field in filter. Following the docs I created custom one. Here is my try:
<?php
namespace SyliusExtensionBundle\Form\Type\Filter;
use Doctrine\ORM\EntityRepository;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
final class TaxonFilterType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('city', EntityType::class, array(
'class' => 'Sylius\Component\Core\Model\Taxon',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('t')
->leftJoin('t.parent', 'taxon')
->where("taxon.code = 'city'");
},
'label' => 'Miasto',
'required' => false
));
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver
->setDefaults([
'label' => false,
'placeholder' => 'sylius.ui.all',
])
->setDefined('fields')
->setAllowedTypes('fields', 'array')
;
}
/**
* {#inheritdoc}
*/
public function getName()
{
return 'sylius_grid_filter_taxon';
}
}
Service configuration:
services:
sylius.grid_filter.entity:
class: SyliusExtensionBundle\Grid\Filter\EntityFilter
tags:
- { name: sylius.grid_filter, type: app_entity, form-type: SyliusExtensionBundle\Form\Type\Filter\EntityFilterType }
- { name: sylius.grid_filter, type: app_taxon, form-type: SyliusExtensionBundle\Form\Type\Filter\EntityFilterType }
sylius.form.type.grid_filter.entity:
class: SyliusExtensionBundle\Form\Type\Filter\EntityFilterType
tags:
- { name: form.type, alias: sylius_grid_filter_entity }
app.form.type.grid_filter.taxon:
class: SyliusExtensionBundle\Form\Type\Filter\TaxonFilterType
tags:
- { name: form.type, alias: sylius_grid_filter_taxon }
And lastly filter templates:
sylius_grid:
templates:
filter:
app_entity: "SyliusExtensionBundle:Grid/Filter:entity.html.twig"
app_taxon: "SyliusExtensionBundle:Grid/Filter:entity.html.twig"
Please guide my how can I restrict EntityFilter or how to make the custom filter work. I spent many hours on this subject and cannot see whereis the error.
Current effect below:
EDIT:
Current TaxonFilterType according to Paweł Jędrzejewski tips. Still doesn't work and dont detect fields option in configuration.

Currently this is not possible via configuration. I will add it to the backlog, but not sure when it can be implemented. That being said, your custom filter is a good idea. You should do a small change and it should work: The form type should have EntityType::class in getParent() instead of using the buildForm method. And the custom query builder should be configured in configureOptions method, then it will render a proper field. Here is full code that should work:
<?php
namespace AcmeExtension\Form\Type\Filter;
use Doctrine\ORM\EntityRepository;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
final class CityFilterType extends AbstractType
{
public function getParent()
{
return EntityType::class;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver
->setDefaults([
'label' => false,
'placeholder' => 'sylius.ui.all',
'class' => 'Sylius\Component\Core\Model\Taxon',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('t')
->leftJoin('t.parent', 'taxon')
->where("taxon.code = 'city'")
;
},
'required' => false
])
->setDefined('fields')
->setAllowedTypes('fields', 'array')
;
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'sylius_grid_filter_city';
}
}
