Error when using ->paginate() with Laravel

Question

So I have this Topic controller on my forum. The Topic has many Posts and the Post belongs to the Topic.

class Topic 
{
    public function posts()
    {
        return $this->hasMany('Post');
    }
}

class Post 
{
    public function topic() 
    {
        return $this->belongsTo('Topic');
    }
}

To get the informations about a Topic and all of the posts related to it, I do:

$query = Topic::where('id', $id)->with('posts');

But every time I try to add :

$query = $query->paginate(15)

and I use $topic->title, I get :

Undefined property: Illuminate\Pagination\Paginator::$title

Any idea? Thank you.

EDIT : Oh and if I use ->get() instead of ->paginate() I don't have errors.

The paginate(15) call returns a Paginator object, holding many Topic items. If you want to get the title field of one of these items, you need to get one of them first. You can do this for example via:

$query->first()->title;

More likely, you will loop through the results and use them like that:

foreach($query as $key => $value)
{
    // do something here, $value contains a Topic object.
    $name = $value->name;
}
