Paginate while returning array Api resource object - laravel

Question

I need to send multiple object to the api resources. So I am returning multiple Object inside array.Everything works fine but not showing any pagination meta data. like Current_page,next_page url etc.
return [
'across_city' => ServiceProviderCollection::collection($across_city),
'near_by' => ServiceProviderCollection::collection($near_by)
];
My resource
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\Resource;
class ServiceProviderCollection extends Resource
{
public function toArray($request)
{
return
[
'name'=>$this->forename,
'rating'=>$this->rating,
'price'=>$this->price,
'distance'=>round($this->distances,1),
];
}
}
My Controller:
here I have two type of users . near_by users and Users across the city. I sent them to the ServiceProviderCollection As an array.
$user_city = $userObj->location->city;
$locationObj = Location::whereNotIn('id', $blockeduser)->where('city',$user_city)->first();
$across_city = $locationObj->users()->simplePaginate(20);
$near_by = User::join('locations as l', 'users.location_id', '=', 'l.id')
->select('users.*', DB::raw('(6371 * acos(cos(radians(' . $coordinates['latitude'] . ')) * cos(radians(`lat`)) * cos(radians(`lng`) - radians(' . $coordinates['longitude'] . ')) + sin(radians(' . $coordinates['latitude'] . ')) * sin(radians(`lat`)))) as distances'))
->having('distances', '<', $max_distance)
->orderBy('distances', 'ASC')
->where('role_id',2)
->whereNotIn('id', $blockeduser)
->simplePaginate(20);
return [
'across_city' => ServiceProviderCollection::collection($across_city),
'near_by' => ServiceProviderCollection::collection($near_by)
];
I want Json Data with pagination.
{"data":{
"across_city": [
{
"name": "??",
"rating": 0,
"price": 0,
"distance": 0,
}
],
"links": {
"first": "",
"last": "",
"prev": null,
"next": ""
},
"meta": {
"current_page": 1,
"from": 1,
"last_page": 3,
"path": "",
"per_page": 2,
"to": 2,
"total": 6
},
{
"near_by": [
{
"name": "??",
"rating": 0,
"price": 0,
"distance": 0,
}
],
"links": {
"first": "",
"last": "",
"prev": null,
"next": ""
},
"meta": {
"current_page": 1,
"from": 1,
"last_page": 3,
"path": "",
"per_page": 2,
"to": 2,
"total": 6
}
}

I have no idea, what the purpose of ServiceProviderCollection is. If it creates a regular collection then there is a better way to do so.
To be able to paginate a simple collection you need to add this helper function to your base:
function paginateCollection($items, $perPage = 15, $page = null, $options = [])
{
$page = $page ?: (\Illuminate\Pagination\Paginator::resolveCurrentPage() ?: 1);
$items = $items instanceof \Illuminate\Support\Collection ? $items : \Illuminate\Support\Collection::make($items);
return new \Illuminate\Pagination\LengthAwarePaginator($items->forPage($page, $perPage), $items->count(), $perPage, $page, $options);
}
With this function in place you can make
return [
'across_city' => paginateCollection(collect($across_city), 20),
'near_by' => paginateCollection(collect($near_by), 20)
];
Edit
Do you have generated the corresponding resource collections?
Like so: php artisan make:resource Cities --collection
If so, you can return a paginated resource collection
