Support for Factories

[joelatgrayv]

Should the Factories work? I get this error:

Call to undefined method Illuminate\Database\Query\Builder::usingModel()

The entry ends up in the local dynamodb but an error is thrown.

Model

 use Kitar\Dynamodb\Model\Model as DynamoModel;

 class ExampleDynamoDbModel extends DynamoModel
{
    use HasFactory;

   protected $connection = 'dynamodb';

    protected $table = 'example_table';
    protected $primaryKey = 'my_primary_key';
    protected $sortKey = 'my_sort_key';
    protected $fillable = [
        'my_primary_key',
        'my_sort_key',
    ];
}

create table '{
  "TableDescription": {
    "AttributeDefinitions": [
      {
        "AttributeName": "my_primary_key","AttributeType": "N"
      },{
        "AttributeName": "my_sort_key","AttributeType": "N"
      }
    ],"TableName": "local_example_table",
    "KeySchema": [
      {
        "AttributeName": "my_primary_key","KeyType": "HASH"
      },{
        "AttributeName": "my_sort_key","KeyType": "SORT"
      }
    ],
    "ProvisionedThroughput": {
      "ReadCapacityUnits": 1,"WriteCapacityUnits": 1
    },
    "TableClassSummary": {
      "TableClass": "STANDARD"
    }
  }
}';

Factory

<?php

namespace Database\Factories\DynamoDb;

use Illuminate\Database\Eloquent\Factories\Factory;

class ExampleDynamoDbModelFactory extends Factory
{

    public function definition(): array
    {
        return [
            'my_primary_key' => $this->faker->randomNumber(),
            'my_sort_key' => $this->faker->randomNumber(),
        ];
    }
}

Seeder

<?php

namespace Database\Seeders;

use App\Models\DynamoDb\ExampleDynamoDbModel;
use Illuminate\Database\Seeder;

class ExampleDynamoDbModelSeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        // This works
        $model = new ExampleDynamoDbModel();
        $model->my_primary_key = rand();
        $model->my_sort_key = rand();
        $model->save();

        // This throws the error
        $data = ExampleDynamoDbModel::factory()->count(1)->create();
    }
}

I have a feeling your model is not using the DynamoDb connection. Try to hard code the connection in your model

protected $connection = 'dynamodb';

[joelatgrayv]

Sorry, I should have included my base model. It does have protected $connection = 'dynamodb';. I'll revise the example. You can see that the single model creation works in the seeder class but the factory create function throws the error.

       // This works
        $model = new ExampleDynamoDbModel();
        $model->my_primary_key = rand();
        $model->my_sort_key = rand();
        $model->save();

        // This throws the error
        $data = ExampleDynamoDbModel::factory()->count(1)->create();

[joelatgrayv]

The Factory was overriding the $connection in the model. For me I additionally had to revise the setConnection method to prevent this:

    protected $connection = 'dynamodb';

    public function setConnection($name)
    {
        // Don't override the $connection
        // $this->connection = $name;
        return $this;
    }
