I want to displaying comments for each post

hello I just moved from php native and want to try relationships in laravel, so I want to display a post and each comment and the name of user who comments so that when looped the post has a comment that has a relationship with it.

So this is my HomeController.php :

public function index() {
        
        $posts = Post::all();
        $comment = Comment::all();
        
        
        return view('home', [
            'posts' => $posts,
            'comments' =>  $comment
        ]);
}

My Post.php :

 public function comments() {
        return $this->hasMany(Comment::class);
    }

  public function user() {
        return $this->belongsTo(User::class);
    }

My Comments.php :

 public function post() {
        return $this->belongsTo(Post::class);
    }

 public function user() {
        return $this->belongsTo(User::class);
    }

My User.php :

 public function post() {
        return $this->hasMany(Post::class);
    }

My home.blade.php :

@foreach ($posts as $post)
        <div class="box-post">
          <p>{{ $post->user->name }}</p>
          <p>{{ $post->post_content}}</p>
          <a href="/comment/{{ $post->id }}"><button>Comment</button></a>
        </div>

        @foreach ($comments as $comment)
           <div class="box-post">{{ $comment->comment_content }} </div>
        @endforeach
@endforeach

the code above runs with the post displayed along with the author but all the comments also appear in all posts, I have searched for references and tried to change the comments value in Controller but the results are still the same so I made the comments appear in each post *$comment = Comment::all();.

what I want is to display posts and comments that relate to each post, like a twitter feature that can reply to people's tweets.

Thx you..

    public function index() {
        
        $posts = Post::with('comments')->get();
        
        
        
        return view('home', [
            'posts' => $posts,
            
        ]);
}

then in blade

    @foreach ($posts as $post)
        <div class="box-post">
          <p>{{ $post->user->name }}</p>
          <p>{{ $post->post_content}}</p>
          <a href="/comment/{{ $post->id }}"><button>Comment</button></a>
        </div>

        @foreach ($post->comments as $comment)
           <div class="box-post">{{ $comment->comment_content }} </div>
        @endforeach
   @endforeach

Your relations builded well, so just can simply use $post->comments can get all comments related on each post.

@foreach ($posts as $post)
        <div class="box-post">
          <p>{{ $post->user->name }}</p>
          <p>{{ $post->post_content}}</p>
          <a href="/comment/{{ $post->id }}"><button>Comment</button></a>
        </div>

        @foreach ($post->comments as $comment) // make changes here
           <div class="box-post">{{ $comment->comment_content }} </div>
        @endforeach
@endforeach

You have done fine job building models and their relationship.

I recommend you change how you call post query.

public function index(Request $request) {
        
        // add eager loading comments for each post and user
        $posts = Post::with('comments', 'user')->get();
        // eager loading user is needed, cause in blade you call $post->user->name
        // calling comments will no longer needed
  
        // return only $posts
        return view('home', compact('posts'));
}

And inside your blade, you can call comments from each post, like this.

@foreach ($posts as $post)
        <div class="box-post">
          <p>{{ $post->user->name }}</p>
          <p>{{ $post->post_content}}</p>
          <a href="/comment/{{ $post->id }}"><button>Comment</button></a>
        </div>

        @foreach ($post->comments as $comment)
           <div class="box-post">{{ $comment->comment_content }} </div>
        @endforeach
@endforeach

That's it and if you use barryvdh/laravel-debugbar , you will see there are only 3 queries run, each one from table posts, comments and users.<br>
And for comments query and users query, not all rows will be fetched,<br>
only related to fetched posts from the 1st query.

Have fun using Laravel Framework!<br>
Your PHP native knowledge/expertise will be very useful and speed up your learning/mastering process.
