Create or merge fields when exporting a model

Hi,

If you want to merge fields on export you can do the following:

1. Change your models/ModelExport.php

   
   class YourmodelExport extends ExportModel
   {
   
   public $table = 'your_table';
   
   protected $appends = [
       'full_name'
   ];
   
   public function exportData($columns, $sessionKey = null)
   {
       $result = self::make()
           ->get()
           ->toArray();
   
       return $result;
   }
   
   public function getFullNameAttribute()
   {
       return $this->firstname . ' ' . $this->lastname;
   }

}

2. Add the fields to your models/yourmodelexport/columns.yaml

columns: ... full_name: Full name
