Subobject in Type

[hniehorster]

Hey, I'm trying achieve something super simple. For data structuring I want some fields to be in a sub object of the parent. While the fields are in the same table. Looks I do something wrong at the Type's or this is not supported by Rebing. Curious how to resolve this.

{ 
  devices(limit:1, page:1) {
    data{
      uuid
      user_uuid
      settings{
        highest
      }
      sounds{
        highest
      }
    }
  }
}

Here settings and sounds are in the same table as the device itself.

public function fields(): array
    {
        return [
            'uuid' => [
                'type'        => Type::string(),
                'description' => 'Represents the internal identifier',
            ],
            'user_uuid' => [
                'type'        => Type::nonNull(Type::string()),
                'description' => 'The unique user Identifier',
            ],
            'settings' => [
                'type'        => GraphQL::type('DeviceSettings'),
                'description' => 'The settings per priority',
            ],
            'sounds' => [
                'type'        => GraphQL::type('DeviceSounds'),
                'description' => 'The sounds settings per priority',
            ],
            'created_at' => [
                'type'        => Type::nonNull(Type::string()),
                'description' => 'The timestamp that the quiet hour has been created',
            ],
            'updated_at' => [
                'type'        => Type::nonNull(Type::string()),
                'description' => 'The timestamp that the quiet hour was last updated',
            ],
        ];
    }

With model:

  protected $fillable = [
        'user_uuid',
        'name',
        'channel',
        'identifier',
        'device_own_identifier',
        'is_system',
        'error_count',
        'datetime',
        'settings_highest',
        'settings_high',
        'settings_normal',
        'settings_low',
        'settings_lower',
        'sound_highest',
        'sound_high',
        'sound_normal',
        'sound_low',
        'sound_lower',
    ];

    protected $casts = [
        'user_uuid'             => 'string',
        'removed_at'            => 'datetime',
        'settings_highest'          => 'boolean',
        'settings_high'             => 'boolean',
        'settings_normal'           => 'boolean',
        'settings_low'              => 'boolean',
        'settings_lower'            => 'boolean',
        'sound_highest'         => 'string',
        'sound_high'            => 'string',
        'sound_normal'          => 'string',
        'sound_low'             => 'string',
        'sound_lower'           => 'string',
    ];

DeviceSettingsType.php

<?php

declare(strict_types=1);

namespace App\GraphQL\Types;

use GraphQL\Type\Definition\Type;
use Rebing\GraphQL\Support\Type as GraphQLType;

class DeviceSettingsType extends GraphQLType
{
    protected $attributes = [
        'name'        => 'DeviceSettings',
        'description' => 'Settings per priority',
    ];

    public function fields(): array
    {
        return [
            'highest' => [
                'type'        => Type::nonNull(Type::boolean()),
                'alias' => 'settings_highest',
            ],
            'high' => [
                'type'        => Type::nonNull(Type::boolean()),
                'alias'       => 'settings_high',
            ],
            'normal' => [
                'type'        => Type::nonNull(Type::boolean()),
                'alias'       => 'settings_normal',
            ],
            'low' => [
                'type'        => Type::nonNull(Type::boolean()),
                'alias'       => 'settings_low',
            ],
            'lowest' => [
                'type'        => Type::nonNull(Type::boolean()),
                'alias'       => 'settings_lowest',
            ],
        ];
    }
}

The selectedFields are correct and matching with the Database.

However the response remains null

{
  "data": {
    "devices": {
      "data": [
        {
          "uuid": "87573109-bd20-4d45-b88b-6c1bef4aa190",
          "user_uuid": "abc640a4-5136-46ae-bf9a-b5c90910cad1",
          "settings": null,
          "sounds": null
        }
      ]
    }
  }
}

Interesting use. How does the resolver on the query look like?

From a GraphQL type / shape view, this is supported.

It's when the SelectFields comes into play, it gets complex and one has to closely look at the query being generated and need to debug there.

The resolve is pretty simple, uses some auth and gets it straight from eloquent.

public function resolve($root, array $args, $context, ResolveInfo $resolveInfo, Closure $getSelectFields)
    {
        $fields = $getSelectFields();

        return Device::where('user_uuid', $context->user()->uuid)
            ->where('is_system', false)
            ->select($fields->getSelect())
            ->paginate($args['limit'], ['*'], 'page', $args['page']);
    }

$fields->getSelect()

Outputs the correct fields (in the alias and no prefixes).

[mfn]

Hmm, I've no further idea currently.

I would not a reproducer to debug (like a repo or so).

Did you check maybe if any of the existing tests matches what you try to achieve?

[hniehorster]

Yeah, did check those... But couldn't find them. I'll check the resolver functions and see if a slight adjustment in there will do the job.

[hniehorster]

And will create a repo over the weekend for you.

Maybe can be something related to the model attribute defined (or not) in your type. SelectFields is something like a black box for me but I see some code that check this attribute.
