Description:

How to apply for casting when there is embedded fields

Steps to reproduce

1. Prepare Create Query

User::create([
    'reg_date' => (new Carbon())->format('Y-m-d'),
    'input_params' => [
      'start_date' => (new Carbon())->format('Y-m-d')
     ],
]);

2. User

namespace App\Models\MongoDb\IpayApp;

use App\Casts\ObjectIdCasts;
use MongoDB\Laravel\Eloquent\Model;
use Illuminate\Database\Eloquent\Factories\HasFactory;

class User extends Model
{
    use HasFactory;
    protected $connection = 'ipay_app';
    protected $table = 'user';
    protected $guarded = [];

    protected $casts = [
        'reg_date' => 'datetime',
        'start_date' => 'datetime',
    ];

}

3. reg date is casting properly, while on start casting not work

Expected behaviour

Both Should Cast Accordingly, i have missing something, let me know

Actual behaviour

reg date is casting properly, while on start casting not work

Edited to add code blocks.

start_date is not the correct field path, it would be input_params.start_date. Off the top of my head I'm not sure if this will work, as you're not embedding a model but "only" storing unstructured data.

The value assigned is a string. In fact, only DateTimeInterface objects can be casted into MongoDB\BSON\UTCDateTime.
