Using a presenter on attributes in a pivot table in Laravel

Question

I'm just wondering how to go about implementing the Presenter pattern for attributes inside of a pivot table? For example, consider this code (it's just an example and is not a replication of my actual code):

@foreach($users->comments as $comment)
 <h1>{{ $comment->title }}</h1> // calls 'title()' in CommentPresenter
 <p>{{ $comment->body }}</p> // calls 'body()' in CommentPresenter...
 <p>{{ is_null($comment->pivot->deleted_at) ? '' : '[REMOVED]' :}} // Where can I put this???
@endforeach

Where can I put that final attributes presenting method? Bearing in mind I also want to be able to use the inverse of this relation.

Any help greatly appreciated

Thanks!

You can override newPivot in your models and then use your own Pivot model. It will be treated mostly like a "normal" Eloquent model so the auto presenter package should work.

Comment model

public function newPivot(Model $parent, array $attributes, $table, $exists)
{
    if($parent instanceof User){
        return new CommentUserPivot($parent, $attributes, $table, $exists);
    }
    return parent::newPivot($parent, $attributes, $table, $exists);
}

User model

public function newPivot(Model $parent, array $attributes, $table, $exists)
{
    if($parent instanceof Comment){
        return new CommentUserPivot($parent, $attributes, $table, $exists);
    }
    return parent::newPivot($parent, $attributes, $table, $exists);
}

CommentUserPivot model

class CommentUserPivot extends \Illuminate\Database\Eloquent\Relations\Pivot {
    // presenter stuff
}
