Delete data using the user form.

First go to routes/web.php file and add this route:

Route::get('/users/posts/delete', function () {
    $user = User::with('posts')->find(1);
    $user->posts()->whereIn('id', [1, 2])->delete();
    return response()->json($user);
});

We open the browser and go to the new URL http://127.0.0.1:8000/users/posts/delete to find that the post has been deleted successfully.

{
  "id": 1,
  "username": "John Doe Updated",
  "created_at": "2023-09-06T17:24:02.000000Z",
  "updated_at": "2023-09-06T18:49:54.000000Z",
  "posts": [
    {
      "id": 5,
      "title": "Post title 5",
      "body": "Post body 5",
      "user_id": 1,
      "created_at": "2023-09-06T17:29:49.000000Z",
      "updated_at": "2023-09-06T17:29:49.000000Z"
    },
    {
      "id": 6,
      "title": "Post title 6",
      "body": "Post body 6",
      "user_id": 1,
      "created_at": "2023-09-06T17:29:49.000000Z",
      "updated_at": "2023-09-06T17:29:49.000000Z"
    }
  ]
}

Delete data using the publication form.

First go to routes/web.php file and add this path:

Route::get('/posts/user/delete', function () {
    $post = Post::with('user')->findOrFail(2);
    $post->delete();
});

We open the browser and go to the new URL http://127.0.0.1:8000/posts/user/delete. We see that the post has been successfully deleted.
