Add a calculated field to Laravel model query

Yes there is? just add this to your Comment model

public function getTagTranslatedAttribute()
{
    return Lang::methodYouWish($this->tag);
}

then you can access this property from comment instance

$comment->tag_translated;

EDIT

You can modify your toArray method, just add it to Comment class

protected $appends = ['tag_translated'];

and then

$comment->toArray();

Add this in your Comment Model:

protected $appends = ['tag_translated'];

public function getTagTranslatedAttribute()
{
    return 'the translated tag';
}

Hope this helps.
