Answer 1

try this

public function show($id){ //<= pass id here
   $post = Post::find($id);
   $comments = Comment::where('post_id', $post->id)->latest()->paginate(20);
   return view('posts.show', compact('post', 'comments'));
}

in view

@foreach($comments as $comment)
  {{ $comment->message }}
@endforeach


{!! $comments->render() !!}

Answer 2

使您的foreach像这样：

 @foreach($post->comments()->paginate(5) as $comment)
