Upload file

Upload a file

For enabling uploading for a field type, you need to proceed with two steps, one in the Pepper class and one in the model class:

Change field type to Upload type in Pepper class:

<?php

namespace App\Http\Pepper;

use Pepper\GraphQL;
use Rebing\GraphQL\Support\Facades\GraphQL as ParentGraphQL;
use GraphQL\Type\Definition\Type;

class Post extends GraphQL
{
    public function setCoverType()
    {
        return ParentGraphQL::type('Upload');
    }

    public function setOptionalFields()
    {
        return [
            'cover_url' => [
                'type' => Type::string(),
                'selectable' => false,
                'resolve' => function ($root) {
                    $root->refresh();
                    return $root->cover;
                }
            ]
        ];
    }
}

Please take note that at this moment, you cannot use the Upload field both as an input type and return type, and they should be different fields as we have two fields, one for uploading an actual file and one for getting the path to uploaded file.

Add attribute mutation to your model to customize uploading behavior. most of the basic form of upload functionality is provided below:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $fillable = [
        'cover',
    ];

    public function setCoverAttribute($file)
    {
        $this->attributes['cover'] = $file->store('posts');
    }
}

Test Query

Test the upload mutation:

mutation($cover: Upload!) {
  insert_post(
    objects: {
      cover: $cover,
    }
  ) {
    id
  }
}

with variables have cover attribute. Read more how to upload file on rebing/graphql-laravel#file-uploads
