Laravel - Multiple Controllers within a View - php

Question

I'm trying to code a simple social media page. The show view should display a post with all the comments for that particular post listed below.
I've tried a couple different approaches with no luck, this is the approach I feel like I might be closet to success with, any suggestions?
I can provide other extracts of code if you think the problem lies elsewhere but I think my problem lies within these 4 files.
web.php
Route::resource('post', 'PostController');
Route::resource('post', 'CommentController');
show.blade.php
<h1>{{$post->title}}</h1>
<p>Description: {{$post->description}}</p>
<h3>Comments</h3>
<ul>
#foreach ($comments as $comment)
<li>
User: {{$comments->user_name}} <br>
Comment: {{$comments->comment}} <br>
</li><br>
#endforeach
</ul>
PostController.php
public function show($id)
{
$post= Post::find($id);
return view('post.show')->with('post', $post);
}
CommentController.php
public function show($id)
{
$comments= Comment::find($id);
return view('post.show')->with('comments', $comments);
}
EDIT 1
Post.php
class Post extends Model
{
protected $fillable = ['title', 'description'];
function user() {
return $this->belongsTo('App\User');
}
function comment() {
return $this->hasMany('App\Comment');
}
}

Answer 1

firstly set the relationship between Post and Comment Model
In Post Model
class Post extends Model
{
public function comments(){
return $this->hasMany(Comment::class);
}
}
In Comment Model
class Comment extends Model
{
public function post(){
return $this->belongsTo(Post::class);
}
}
Post Controller
public function show($id)
{
$post= Post::find($id);
return view('post.show')->with('post', $post);
}
Write in the blade file
<h1>{{$post->title}}</h1>
<p>Description: {{$post->description}}</p>
<h3>Comments</h3>
<ul>
#foreach ($post->comments as $comment) //get all the comments related to this post
<li>
User: {{$comment->user_name}} <br>
Comment: {{$comment->comment}} <br>
</li><br>
#endforeach
</ul>

Answer 2

You can get both data by make relations between your models
I think in your two models the relation would be like that,
Post Model
namespace App\Post;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
public function comments(){
return $this->hasMany(Comment::class);
}
}
Comment Model:
namespace App\Comment;
use Illuminate\Database\Eloquent\Model;
class Comment extends Model
{
public function post(){
return $this->belongsTo(Post::class);
}
}
so if you want to return the data to view then,
PostController.php
public function show($id)
{
$post= Post::with('comments')->find($id);
$data = [
'post' => $post,
'comments' => $post->comments,
];
return view('post.show', $data);
}
CommentController.php
public function show($id)
{
$comments= Comment::with('post')->find($id);
$data = [
'post' => $comments->post,
'comments' => $comments,
];
return view('post.show' , $data);
}
