Say*_*Das 5 php pagination laravel
我的问题:我需要在我尝试使用 laravel 开发的简单 api 中使用分页。我正在使用游标来做到这一点。但是即使我的模型正在返回结果,结果也是空白的。
我的代码:
$newCursor = $groups->last()->id;
$cursor = new Cursor($cursor, $previousCursor, $newCursor, $groups->count());
//dd($cursor);
$groups = new Collection(fractal($groups, new GroupRequestTransformer('filtered')));
$groups->setCursor($cursor);
$data = [
'groups' => $groups,
'cursor' => $cursor
];
$this->setResponseStatus(true, 200, trans('group.filtered'));
return $this->sendResponseData($data);

注意:$groups具有从模型返回的值。如果我dd($cursor);,我得到
Cursor {#403
#current: "5"
#prev: null
#next: 13
#count: 1
}

所以这似乎很好。但是我发送的实际响应$data是空白的。
"data": {
"groups": {},
"cursor": {}
}

我在这里缺少什么?

use fractal's paginator instance to format the paginated collection no need to use cursor below is the example on their site
use League\Fractal\Resource\Collection;
use League\Fractal\Pagination\IlluminatePaginatorAdapter;
use Acme\Model\Book;
use Acme\Transformer\BookTransformer;
$paginator = Book::paginate();
$books = $paginator->getCollection();
$resource = new Collection($books, new BookTransformer);
$resource->setPaginator(new IlluminatePaginatorAdapter($paginator));

或者使用 laravel-fractal 一个方便的包,它支持所有类型的分页和所有内容。 https://github.com/spatie/laravel-fractal
