How to get args, info, context or value in a resolver declared with #[GQL\Query]? #1160

I'm implementing a resolver that add a field to an existing type and I want to access the the value of this object type (to get its id and do some sql queries for example)

I might have missed it but I couldn't find how to do this easily. I first tried something like this:

#[GQL\Provider]
final class UserExtension
{
 #[GQL\Query(targetTypes: 'User')]
 public function something(User $user): int
 {
 return $this->computeSomething($user->id);
 }
}

hoping that it would get auto-injected, but it's not (I was not really expecting to work, but it would be nice to be able to implement something like that, something à la Symfony ValueResolverInterface like discussed in #875 would be nice)

next step was to specify the $resolve argument of #[GQL\Query], and after a few tries I go it working with this:

#[AsAlias('gql.user.something', public: true)]
#[GQL\Provider]
final class UserExtension
{
 #[GQL\Query(
 targetTypes: 'User',
 name: 'something',
 resolve: '@=call(service("gql.user.something").something, [value])',
 )]
 public function fake(): array
 {
 throw new \LogicException('TODO: figure out how we can get rid of this fake method');
 }
 public function something(User $user): int
 {
 return $this->computeSomething($user->id);
 }
}

but this means:

• I need to make the service (or an alias as in my example) public to be able to call it in the resolve: expression
• I can't have arguments on the method with the #[GQL\Query] attribute as the bundle would try to expose them as GraphQL arguments

but at least it works :)

then I had a case where I want to have the value and a GraphQL argument, so I tried something like this:

#[AsAlias('gql.user.something', public: true)]
#[GQL\Provider]
final class UserExtension
{
 #[GQL\Query(
 targetTypes: 'User',
 name: 'something',
 resolve: '@=call(service("gql.user.something").something, [value, ...args])',
 )]
 public function fake(int $foo): array
 {
 throw new \LogicException('TODO: figure out how we can get rid of this fake method');
 }
 public function something(User $user, int $foo): int
 {
 return $this->computeSomething($user->id, $foo);
 }
}

but this doesn't work because unpacking with ... isn't supported in expressions, so [value, ...args] doesn't work.

Is there a better way to do this? I would really like to this with attributes on DTO instead of doing too much stuff "manually" so that everything is less error-prone.

maybe something like this:

#[GQL\Provider]
final class UserExtension
{
 #[GQL\Query(targetTypes: 'User')]
 public function something(
 #[GQL\Expr('value') User $user,
 int $foo,,
 ): int {
 return $this->computeSomething($user->id, $foo);
 }
}

wdyt? or again, maybe I've missed something?

thank you,
