### Update data using the user form.

1- Using ***`push method`***.

* First go to ***`routes/web.php`*** file and modify this route:
```PHP
Route::get('/users/update', method () {
    $user = User::with('posts')->find(1);
    $post = $user->posts()->whereId(1)->first();
    $post->title = 'Post title 1 updated';
    $post->push();
    return response()->json($user);
});
```

* We open the browser and go to the new URL ***`http://127.0.0.1:8000/users/update`*** to find that the post has been updated successfully.
```json
{
  "id": 1,
  "username": "John Doe",
  "created_at": "2023-09-06T17:24:02.000000Z",
  "updated_at": "2023-09-06T17:25:58.000000Z",
  "posts": [
    {
      "id": 1,
      "title": "Post title 1 updated",
      "body": "Post body 1",
      "user_id": 1,
      "created_at": "2023-09-06T17:28:58.000000Z",
      "updated_at": "2023-09-06T18:37:30.000000Z"
    },
    {
      "id": 5,
      "title": "Post title 5",
      "body": "Post body 5",
