Cutted string when get value of field

Question

Anyone can explain why when access to field only return part of string?

Answer 1

Can you check your CursSM model file, there may be a attribute casting, which override the result. Check the additional information in laravel documentation - https://laravel.com/docs/9.x/eloquent-mutators

Answer 2

I can't understand!

Model was:

class cursSM extends Model
{
    use HasFactory;

    protected $table = 'curs_sm';
    protected $primaryKey = 'curs';

    public $timestamps = false;
}

changed to

class cursSM extends Model
{
    use HasFactory;

    protected $table = 'curs_sm';
}

now works fine!
