Allow more filters on specific route on GetCollection

[Cryde]

Hello

I would like to know if it's possible to give access to certain filters for only one GetCollection route.
Example :

#[ApiResource(
    operations: [
        new GetCollection( // this one shouldn't have access to the "status" filter 
            uriTemplate: '/my-collection/',
            name: 'api_get_collection'
        ),
        new GetCollection( // this one should have access to more filters like on "status" for instance
            name: 'api_user_get_collection',
            uriTemplate: '/users/my-collection/',
            provider: MyProvider::class
        )
    ]
)]
#[ApiFilter(filterClass: OrderFilter::class, properties: ['publicationDatetime' => OrderFilterInterface::DIRECTION_DESC])] // default order everyone have : order on date
#[ApiFilter(filterClass: SearchFilter::class, properties: ['category' => SearchFilterInterface::STRATEGY_EXACT])] // default filter everyone have : search item on specific category
class Post
{
  private $id;
  private Category $category;
  private ?DateTimeInterface $publicationDatetime = null;
  private int $status = self::STATUS_DRAFT;
}

Does anyone have face this kind of needs ?
Thank you for

I haven't done that before, but as a workaround you probably could make a custom Filter that does nothing when called on the other Operation - it's available in the filterProperty() parameters. Then you'd just forward the call to the filter you really want if it's the right operation?

Yes it could be a solution I guess !
It would have been nice if we could "plug" some filters to operation directly (there is a field filters inside GetCollection but I don't know if it works the same way than other filters)

It looks like this is actually possible by declaring a service, similar to the example in https://api-platform.com/docs/core/filters/#manual-service-and-attribute-registration

services:
    'app.filter.book.search':
        class: 'ApiPlatform\Doctrine\Orm\Filter\SearchFilter'
        arguments: [ '@doctrine', '@api_platform.iri_converter', ~, '@logger', { 'title': ~ } ]
        tags: [ 'api_platform.filter' ]

new GetCollection(filters: ['app.filter.book.search']),

Discussion in #5665 of having an easier syntax

Thanks to #6244 it'll be possible to declare parameters on an operation-basis in API Platform 3.3.
