how to sort a merged object in laravel - php

Question

i have 2 objects that i use merge on them like below :
$data = $city->merge($accommodation);
return AccCitySearchResource::collection($data);
and in my resource
return [
'id' => $this->id,
'name' => $this->name,
'english_name' => $this->english_name,
'accommodation_type_id' =>$this->accommodation_type_id,
'grade_stars' =>$this->grade_stars,
'hits' =>$this->hits,
'accommodation_count' => $this->accommodation_count,
];
now all i want is that my $data first shows all cities and then shows all accommodations but now it shows all together is there any way to sort them ??
EDIT
This is what i get now
{
id: 5,
name: "hotel",
accommodation_type_id: 1,
grade_stars: 4,
hits: 22,
accommodation_count: null
},
{
id: 7,
name: "city",
accommodation_type_id: null,
grade_stars: null,
hits: null,
accommodation_count: 0
},
{
id: 10,
name: "hotel",
accommodation_type_id: 1,
grade_stars: 2,
hits: 0,
accommodation_count: null
},
And this is what i want
{
id: 5,
name: "hotel",
accommodation_type_id: 1,
grade_stars: 4,
hits: 22,
accommodation_count: null
},
{
id: 10,
name: "hotel",
accommodation_type_id: 1,
grade_stars: 2,
hits: 0,
accommodation_count: null
},
{
id: 7,
name: "city",
accommodation_type_id: null,
grade_stars: null,
hits: null,
accommodation_count: 0
},
just to mention as you see all hotels comes first and then all cities come .

Answer 1

The recommended way in the documentation is to create your own resource collection if you need to customise the default behavior:
php artisan make:resource AccCitySearchCollection
Then you can customise your collection:
class AccCitySearchCollection{
public function toArray($request)
{
return [
'data' => $this->collection->sortBy('name')
];
}
}
You can then return a collection instance:
$data = $city->merge($accommodation);
return new AccCitySearchCollection($data);

Answer 2

You can use sortBy Collection method
Created Resource Collection for model.
Then in toArray method write:
/**
* Transform the resource collection into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
return [
'data' => $this->collection->sortByDesc(function($d){
return (int) ($d['name'] == 'hotel');
}),
];
}
This will sort your data as you want.
Hope this answer helps you

Answer 3

Maybe something like this ... But if you are getting your data from a database , maybe you could join and order the query instead..
$data = $city->merge($accommodation)->sortByDesc('some field of first object here');
