Check your view blade, that method links() only could be used when your data model is implementing paginate method. If you dont use paginate remove this part:
检查您的视图刀片，该方法 links() 只能在您的数据模型实现分页方法时使用。如果你不使用 paginate 删除这部分：
{{$messages->links()}}
回答by stanley mbote
If you are trying to paginate your data when it gets to the view then you need to add the paginate in your controller before passing the data to the view. Example
如果您试图在数据到达视图时对其进行分页，那么您需要在将数据传递到视图之前在控制器中添加分页。例子
return $users = Users::select('id','name')->paginate(10);
with that paginate method in your controller, you can call the links method to paginate your object in view as shown below
使用控制器中的分页方法，您可以调用 links 方法在视图中对对象进行分页，如下所示
{{$user->links()}}

You can do something like this in your controller file.
您可以在控制器文件中执行类似操作。
public function index()
{
$messages = Message::all()->paginate(5);
$user_id = auth()->user()->id;
$user = User::find($user_id);
return view('message.index')->with('messages', $messages, $user->message);
}
