How can I pass an AbstractQueryFilter or its filters to a Job in Laravel without encountering the 'Serialization of 'Closure' is not allowed' error?

To pass an AbstractQueryFilter or its filters to a Laravel Job without encountering the 'Serialization of Closure is not allowed' error, you need to convert the filter or its components into an array or object that can be serialized. Here's a step-by-step guide on how to do it:

1. Define your AbstractQueryFilter or custom filter class:

Let's assume you have an AbstractQueryFilter class called CustomFilter with a method apply that returns a closure.

namespace App\Filters;

use Illuminate\Database\Eloquent\Builder;

abstract class CustomFilter
{
    abstract protected function filter(Builder $query);

    public function apply(Builder $query)
    {
        return $this->filter($query);
    }
}

2. Create a concrete filter class:

Create a concrete filter class that extends the CustomFilter abstract class and implement the filter method.

namespace App\Filters;

use App\Filters\CustomFilter;

class NameFilter extends CustomFilter
{
    protected function filter(Builder $query)
    {
        return $query->where('name', 'like', '%' . request()->query('name') . '%');
    }
}

3. Convert the filter to an array or object:

Instead of passing the filter instance directly to the job, convert it to an array or object that can be serialized. In this example, we'll convert it to an array.

use App\Filters\NameFilter;

$filter = new NameFilter();
$filterArgs = [
    'filterClass' => NameFilter::class,
    'filterArgs' => [
        'name' => request()->query('name'),
    ],
];

4. Pass the filter arguments to the job:

Now, you can pass the filter arguments to the job.

use App\Jobs\ProcessDataJob;

$job = new ProcessDataJob($filterArgs);
$job->handle();

5. Implement the job:

In the ProcessDataJob class, you can access the filter arguments and create the filter instance when needed.

namespace App\Jobs;

use App\Filters\CustomFilter;
use App\Filters\NameFilter;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\SerializesModels;

class ProcessDataJob implements ShouldQueue
{
    use Dispatchable, SerializesModels;

    protected $filterArgs;

    public function __construct(array $filterArgs)
    {
        $this->filterArgs = $filterArgs;
    }

    public function handle()
    {
        $filterClass = $this->filterArgs['filterClass'];
        $filter = app($filterClass);
        $query = app('Illuminate\Database\Eloquent\Model')->query();
        $filter->apply($query);

        // Process the data using the filtered query
    }
}

By converting the filter to an array or object that can be serialized, you can pass it to a Laravel Job without encountering the 'Serialization of Closure is not allowed' error.
