错误:在非对象上调用成员函数paginate()

Question

我正在尝试将从Eloquent模型中检索到的一些数据转换为对象，然后也使用Laravel的分页功能。但是，当我将数据强制转换为数组以进行转换时，就不能使用paginate方法了。

$postsPerPage = 10;
$posts = Post::where('published', '=', true)->get();
$posts = Helpers::transform_posts($posts->toArray());
// $posts = Helpers::transform_posts($posts->toArray())->paginate($postsPerPage);
// doesn't work because $posts has been cast to an array
// error: Call to a member function paginate() on a non-object
return View::make('blog.index', ['posts' => $posts]);

类助手:

public static function transform_post(array $post)
{
    $publishedDate = CarbonCarbon::createFromTimeStamp(strtotime($post['published_date']))->diffForHumans();
    return [
        'id' => $post['id'],
        'title' => $post['title'],
        'slug' => $post['slug'],
        'subtitle' => $post['subtitle'],
        'body' => $post['body'],
        'published' => (bool)$post['published'],
        'published_date' => $post['published_date'],
        'published_date_for_humans' => $publishedDate
    ];
}
public static function transform_posts(array $posts)
{
    foreach ($posts as &$array) {
        $array = Helpers::transform_post($array);
    }
    return $posts;
}

我怎么能做到这一点，而不强制转换到一个数组，这样我仍然可以在数据上使用分页方法?

编辑:这现在解决了:

    $posts = Post::where('published', '=', true)->get()->toArray();
    $posts = Helpers::transform_posts($posts);
    $posts = Paginator::make($posts, 0 , $postsPerPage);
    return View::make('blog.index', ['posts' => $posts]);

Answer 1

试一试:

$posts = Post::where('published', '=', true)->get()->toArray();
$paginator = Paginator::make($posts, $totalItems, $perPage);

Answer 2

您是否尝试过在没有将$posts转换为数组的情况下进行分页?

$posts = Post::where('published', '=', true)->paginate($postsPerPage);
