Accociate a user name to the post they created - php

Question

If I created a blog post, how can I have my name associated with it? For example, on a page that lists all blog posts, I will see the user name of the post they created. Yes?
In my post controller:
public function __construct(Post $post, User $user)
{
$this->middleware('auth',['except'=>['index','show',]]);
$this->post = $post;
$this->user = $user;
}
public function show($id)
{
$user = $this->user->first(); // This seems to show the first user
$post = $this->post->where('id', $id)->first(); // Grabs the assigned post
}
In my show.blade.php:
{{ $user->name }}
How can I display the name of the user who created the post? I thought this $user = $this->user->first(); would work. Im new to Laravel and I am using Laravel 5.
Thanks!
EDIT
User Model:
class User extends Model implements AuthenticatableContract, CanResetPasswordContract, BillableContract {
use Authenticatable, CanResetPassword;
use Billable;
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'users';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = ['name', 'email', 'password', 'company_url', 'tagline','company_name', 'company_description'];
/**
* The attributes excluded from the model's JSON form.
*
* #var array
*/
protected $hidden = ['password', 'remember_token'];
/**
* #var array
*
*/
protected $dates = ['trial_ends_at', 'subscription_ends_at'];
public function posts()
{
return $this->hasMany('App\Post')->latest()->where('content_removed', 0);
}
}
Post Model:
class Post extends Model {
/**
* Fillable fields for a new Job.

protected $fillable = [
'post_title',
'post_description',
'post_role',

public function users()
{
return $this->hasMany('App\User')->orderBy('created_at', 'DESC');
}
public function creator()
{
return $this->belongsTo('App\User');
}
}

Answer 1

first
you need to add the following line to your post model
public function creator()
{
return $this->belongsTo('App\User','user_id', 'ID');
}
then in you show method
public function show($id)
{
$post = $this->post->with('creator')->findOrFail($id);
return view('show',compact('post'));
}
In you show.blade.php
{{ $post->creator->name }}
