Relationships and displaying data.

I have two models Users, Posts. Either I am not doing the relationships correctly or there is something I am missing but it is not displaying anything. No error, just empty field on my view

User Model

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

Post Model

public function users(){
        return $this->belongsTo('App\User');
    }

Controller

 public function getSingle($slug)
    {
       $post = Post::where('slug', '=', $slug)->first();
       return view('blog.single')->with('post', $post);

    }

How I Display The Data

{{$post->user['name']}}
