Transform eloquent model using fractal - php

Question

I am trying to use fractal to convert dates in my eloquent model when sending it to a web page via ajax. However, I'm not getting the expected transformed data object. Here's my code:
Transformer:
<?php
namespace App\Transformers\Models;
use App\Models\Student;
use League\Fractal;
class StudentTransformer extends Fractal\TransformerAbstract
{
public function transform(Student $student)
{
return [
'name' => $student->name,
'birth_date' => date('d-m-Y', strtotime($student->birth_date)),
'start_date' => date('d-m-Y', strtotime($student->start_date)),
'is_active' => $student->is_active ? 'Yes' : 'No',
'course_title' => $student->course_title,
'university_id' => $student->university_id,
'institution_id' => $student->institution_id,
'course_id' => $student->course_id,
];
}
}
Routes file:
Route::get('/', function () {
$student = App\Models\Student::first();
$response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer);
return response()->json([$response]);
});
returns this:
[
{ }
]
if I dd(), like so:
Route::get('/', function () {
$student = App\Models\Student::first();
$response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer);
dd($response);
});
I get the following, with no apparent transformations made
Item {#299 ▼
#data: Student {#305 ▼
#fillable: array:10 [▼
0 => "name"
1 => "birth_date"
2 => "start_date"

5 => "university_id"
6 => "institution_id"
7 => "course_id"
]

Any ideas what I'm missing here?

Answer 1

My implementation is the following :
Route::get('/', function () {
$student = App\Models\Student::first();
$response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer);
$manager = new \League\Fractal\Manager();
$manager->setSerializer(new \League\Fractal\Serializer\ArraySerializer());
return response()->json($manager->createData($response)->toArray());
});
You have to create a \League\Fractal\Manager instance and assign a serializer into it. The manager will return the data into array or others.
In fractal page, there is more detail.

Ive not used Factral in a project but I think you need to do something like.
Route::get('/', function () {
$student = App\Models\Student::first();
$response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer);
return response()->json($response->toArray());
});
