How to change connection of eager loading? - laravel

Question

These are my models
class Posts extends Model {
protected $connection = 'connection_1';
public function comments()
{
$model = new Comments();
$model->setConnection($this->connection);
return $this->hasMany($model, 'comments_id');
}
}
class Comments extends Model {
protected $connection = 'connection_1';
public function author()
{
$model = new Authors();
$model->setConnection($this->connection);
return $this->hasOne($model, 'id', 'authors_id');
}
public function post()
{
$model = new Posts();
$model->setConnection($this->connection);
return $this->hasOne($model, 'id', 'posts_id');
}
}
class Authors extends Model {
protected $connection = 'connection_1';
public function comments()
{
$model = new Comments();
$model->setConnection($this->connection);
return $this->hasMany($model, 'authors_id');
}
}
When i put this code in my controller, Comments model is connected to connection_2 but Authors is empty, i guess it's not changing connection to connection_2
$posts = new Posts;
$posts->setConnection('connection_2');
$posts->load("comments.author")->get();
How can I change dinamically Authors model connections, or why Authors is empty?

Answer 1

I have resolved my problem like this:
$conn = \App\Helpers\Helper::connection($item_id);
$newPdo = \DB::connection($conn)->getPdo();
\DB::setPdo($newPdo);
$posts = \App\Posts::with("comments.author")->get();
And in my helper
public static function connection($project) {
switch($project) {
case 01:
return 'connection_01';
break;
case 02:
return 'connection_02';
break;
case 03:
return 'connection_03';
break;
}
}
