Laravel 5.3過濾后的鏈分頁

Question

$posts = Post::all()->filter(function($item) use (&$pYear){
    return Persian::jDate(...) == $pYear;
})->sortByDesc('id')->paginate(5);

當我鏈接paginate（5）時，出現此錯誤“方法paginate不存在。”，我如何對我的結果進行分頁，請幫忙，謝謝。

Answer 1

最后，我通過創建我的收藏夾的自定義分頁器解決了它，也許這不是最好的方法，我找不到更短的解決方案，無論如何我的代碼現在都可以正常工作。

use Illuminate\Pagination\LengthAwarePaginator;

protected $perPage = 5;

$posts = Post::get()->filter(function($item) use (&$pYear){
    return Persian::jDate(...) == $pYear;
})->sortByDesc('id');

//this code simulates: ->paginate(5)
$posts = new LengthAwarePaginator(
         $posts->slice((LengthAwarePaginator::resolveCurrentPage() *
         $this->perPage)-$this->perPage,
         $this->perPage)->all(), count($posts),
         $this->perPage, null, ['path' => '']);
 

Answer 2

嘗試刪除all()

$posts = Post::filter(function($item) use (&$pYear){
    return Persian::jDate('Y', strtotime($item->created_at),'','Asia/Tehran','en') == $pYear;
})->sortByDesc('id')->paginate(5);
