I need to run the factory 50 times, so within DatabseSeeder:
public function run()
{
for($i=1;$i<=50;$i++){
(new CategoryQuestionFactory($i))->create();
}
}
As you can see, I tried passing a variable named $i as a parameter to the CategoryQuestionFactory class.
Then in this factory I tried this:
class CategoryQuestionFactory extends Factory
{
protected $counter;
public function __construct($c)
{
$this->counter = $c;
}
/**
* Define the model's default state.
*
* @return array<string, mixed>
*/
public function definition()
{
$question = Question::find($this->counter);
return [
'category_id' => $this->faker->numberBetween(1,22),
'question_id' => $question->id
];
}
}
But when I run php artisan db:seed in the terminal, I get this error:
Call member function pipeline() on null
exist C:xampphtdocsforumrootvendorlaravelframeworksrcIlluminateDatabaseEloquentFactoriesFactory.php:429
So what’s the problem here? How to correctly send values as parameters to factory classes?
Additionally, in the IDE for the factory's __construct method, I get the following message:
The following is the error capture in the IDE:

It seems to me that you want to seed the intermediate table. There are a few methods you can use when seeding, one of them is
has(), which is the method I often use./** * will create a one question and 3 category then create a data in the intermediate table. * expected data : * question_id | category_id * 1 1 * 1 2 * 1 3 */ Question::factory()->has( Category::factory()->count(3) )->create();Suppose you want to create 100 questions and 5 categories
/** * will create a 100 question and 5 category then create a data in the intermediate table. * expected data : * question_id | category_id * 1 1 * 1 2 * 1 3 * 1 4 * 1 5 * 2 1 * 2 2 * 2 3 * 2 4 * 2 5 * until the 100th question will have a 5 categories */ Question::factory(100)->has( Category::factory()->count(5) )->create();
