When we create a blog, it belongs to a blog, but also a user. How to tidy things up.



```php
class PostsController extends Controller
{
	public function store(Request $request, Topic $topic)
	{
		$topic->posts()->create([
			'body' => 'Test body',
			'user_id' => $request->user()->id
		]);
	}
}
```


It works but the user is associated, but it makes more sense to use the following way

```php
class PostsController extends Controller
{
	public function store(Request $request, Topic $topic)
	{
		$post = new Post($request->only(['body']));
		$post->user()->associate($request->user());
		$topic->posts->save($post):
	}
}
```
