Laravel 8 Undefined variable: comments - php

Question

I am trying to build a commenting system where users are able to leave comments behind on posts.
I can save and display the post and on a page i display all post I have a form where users can leave comments behind. I am able to save the comments in the database but when I try to show the comments I get this error Undefined variable: comments (View: /var/www/resources/views/projects/comment.blade.php).
My files: Comment Model:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Comment extends Model
{
use HasFactory, SoftDeletes;
protected $dates = ['deleted_at'];
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = ['user_id', 'post_id', 'parent_id', 'description'];
/**
* Write Your Code..
*
* #return string
*/
public function user()
{
return $this->belongsTo(User::class);
}
/**
* Write Your Code..
*
* #return string
*/
public function replies()
{
return $this->hasMany(Comment::class, 'parent_id');
}
}
Post Model:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class post extends Model
{
use HasFactory, SoftDeletes;
protected $dates = ['deleted_at'];
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [ 'titre',
'description',
'image',
'tag',
'video',
'status',
'user_id'];
/**
* Write Your Code..
*
* #return string
*/
public function comments()
{
return $this->hasMany(Comment::class)->whereNull('parent_id');
}
}
My CommentController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Comment;
class CommentController extends Controller
{
/**
* Write Your Code..
*
* #return string
*/
public function store(Request $request)
{
$input = $request->all();
$request->validate([
'body'=>'required',
]);
$input['user_id'] = auth()->user()->id;
Comment::create($input);
return back();
}
}
post display controller
public function post_display()
{
if(Auth::id()){
$userid=Auth::user()->id;
$profile=user::find($userid);
$post=post::where('user_id',$userid)->get();
return view('user.post_display',compact('post','profile'));
}
else{
return redirect()->back();
}
}
