Cannot display comments for post

Question

Basically, I want to show a posts comment.

Whatt is supposed to happen is that,when a user goes to view a post using a url such as http://localhost:8000/post/show/1,their supposed to be able to to type a comment on a post,press 'submit' ,the comment data inserted into the database,the page should reload and the comments on that post should be shown including the comment just commented by the user

BUT what currently happens is that after typing the comment in http://localhost:8000/post/show/1 it inserts the comment data into the database,reloads the page but does not show any comment on that page.

I have no clue what I'm doing wrong.

Please help

Answer 1

Update the PostControllerfunction as below:

public function show($id)
{
  $post = Post::where('id', $id)->with('comments.user')->first();
  return view('show', compact('post'));
}

It should get comments and user details attached

On the Post Model, update comments function

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