Resolver Array type with key value

[darkiron]

Hi,
I try to resolve a collection as associative array withe key value, I don't know how I do proceed

my query look like:

      Product(
        productId: $productId
 {
        productId
  	  productImages {
          name
        }
    }
}

I expected for productImages:

"MY_KEY_1": {
     name: "image_name"
},
"MY_KEY_2": {
     name: "image_name_2"
},

Thanks for your help

Its long time but anyway here is possible solution:

class KeyValue extends ObjectType
{
    public function __construct()
    {
        parent::__construct([
            'name' => 'KeyValue',
            'fields' => [
                'key' => [
                    'type' => Type::nonNull(Type::string()),
                    'resolve' => static fn($rootValue) => $rootValue['key'],
                ],
                'value' => [
                    'type' => Type::nonNull(Type::string()),
                    'resolve' => static fn($rootValue) => $rootValue['value'],
                ],
            ],
        ]);
    }
}

In your type add a new field:

    'fields' => [
        'list' => [
            'type' => Type::listOf(new KeyValue()),
            'resolve' => static function() {
                return [
                    [
                        'key' => 'foo',
                        'value' => 'bar'
                    ]
                ];
            }
        ]
    ],
...

will result:

{
    "data": {
        ...
            "list": [
                {
                    "key": "foo",
                    "value": "bar"
                }
            ]
...
}

This or a variation of it is really the only possible solution, GraphQL does not allow maps with arbitrary keys. Field names always have to be explicitly defined in the schema.
