当我通过Postman上的PUT方法更新数据时，我收到了这个错误消息。

No query results for model [App\Models\Post].

代码

public function store(Request $request)
    {
        $post = $request->isMethod('put') ? Post::findOrFail
        ($request->post_id): new Post;

        $post->id= $request->input('id');
        $post->title= $request->input('title');
        $post->body= $request->input('body');

        if($post->save()){
            return response($post);
        }
    }
