Resolving type, need data that I don't have

[edalzell]

Sorry if this is in the docs somewhere I looked and didn't see anything. Also looked to see if there was an issue for this.

I have a custom type Row that needs some data/config for the attributes to work:

    public function fields()
    {
        $fields = collect($this->fields)
            ->map(function ($field, $ignored) {
                return [
                        'type' => $this->getType($field),
                        'description' => array_get($field, 'display'),
                        'resolve' => [$this, 'resolveField'],
                    ];
            });

        return $fields->all();
    }

I need the $this->fields to be passed in during instantiation of the RowType. But I don't see in the parent object how to pass this in. This is how it's set in the parent, as part of the fields() call:

 getType method...
                return Type::listOf(GraphQL::type('Row'));

in here:

                return [
                        'type' => $this->getType($field),
                        'description' => array_get($field, 'display'),
                        'resolve' => [$this, 'resolveField'],
                    ];

If I had this, then I could make Statamic, a wicked CMS built on Laravel, also support GraphQL.

This is needed because the items in a row are defined elsewhere and I don't have enough information in that fields call to figure it out.

AFAIK the types are "maked" via Laravel, i.e. you can inject any dependency you want via the constructor; did you give this a try?

Sorry, I'm not explaining myself very well.

This is for Statamic. The data definitions are not fixed, so I need a generic solution. Here's an example definition (called a fieldset) of a User:

title: User
hide: true
taxonomies:
  class:
    max_items: 1
    sort: title:desc
sections:
  main:
    display: Main
    fields:
      username:
        type: text
        display: Username
        width: 50
      email:
        type: text
        display: Email address
        width: 50
      first_name:
        type: text
        display: First Name
        width: 50
        validate: required
      last_name:
        type: text
        display: Last Name
        width: 50
        validate: required
      roles:
        type: user_roles
        width: 50
        display: Roles
      biography:
        type: text
        width: 50
      photo:
        type: assets
        display: Photo
        container: main
        folder: screenshots
        max_files: 1
        restrict: false
        width: 50
        validate: required
      content:
        type: textarea
        display: Biography
      grid:
        mode: table
        fields:
          text:
            type: text
            display: text
          radio:
            options:
              one: One
              two: Two
            inline: true
            type: radio
            display: radio
        type: grid
        display: grid

And here's what the corresponding data looks like:

Each fieldset can have various fields, each site is different. There are a fixed number of fields, include two that are "lists", grid and replicator. I'm focused on grids right now. A grid is essentially a table, or list of rows, each row having various fields.

The challenge is, when I resolved the Row, I don't have access to the "fieldset" to get the list fields for that row.

HEre's my UserType:

    public function fields()
    {
        $fields = collect(FieldsetAPI::get('user')->fields())
            ->map(function ($field, $ignored) {
                return [
                        'type' => $this->getType($field),
                        'description' => array_get($field, 'display'),
                        'resolve' => [$this, 'resolveField'],
                    ];
            })->put('id', [
                'type' => Type::nonNull(Type::id()),
                'description' => 'The id of the user',
                'resolve' => [$this, 'resolveField'],
            ]);

        return $fields->all();
    }

    // this has to be public for some reason
    public function resolveField(User $user, $args, $context, ResolveInfo $info)
    {
        return array_get($user->toArray(), $info->fieldName);
    }

    private function getType($field)
    {
        /**
         * @todo how to handle all the different fields types
         * @todo how to handle the composite types, like grids of things
         * @todo how to handle the "related" types, like relate or taxonomy
         * @todo add Date type
         */
        switch ($field['type']) {
            case 'toggle':
                return Type::boolean();
                break;
            case 'redactor':
            case 'template':
            case 'text':
            case 'textarea':
            case 'video':
            case 'yaml':
                return Type::string();
                break;
            case 'assets':
            case 'checkboxes':
            case 'list':
            case 'radio':
            case 'select':
            case 'tags':
                if (array_get($field, 'max_files', 1) > 1 ||
                    array_get($field, 'max_items', 1) > 1) {
                    return Type::listOf(Type::string());
                } else {
                    return Type::string();
                }
                break;
            case 'bard':
            case 'replicator':
                break;
            case 'grid':
                // right here I *DO* have the fields, I'd love to pass something to the RowType, like the list of fields
                return Type::listOf(GraphQL::type('Row'));
                break;
            default:
                return Type::listOf(Type::string());
        }
    }

Because in the RowType fields() method:

    public function fields()
    {
        $fields = collect($this->fields)
            ->map(function ($field, $ignored) {
                return [
                        'type' => $this->getType($field),
                        'description' => array_get($field, 'display'),
                        'resolve' => [$this, 'resolveField'],
                    ];
            });

I need to have the list of fields, which I don't. I can't pass it in the constructor because I don't know it there, and data type might have multiple grids, each with different kinds of rows (different fields).

If the type() method took a 3rd parameter that was passed into buildObjectTypeFromClass then I might have access to it somewhere else, like in the constructor or something.

Sorry if that's not clear, this is hard to write out clearly.
