使用分形轉換雄辯模型

Question

我嘗試使用fractal將模型中的日期轉換爲通過ajax發送到網頁時的日期。但是，我沒有得到預期的轉換數據對象。這裏是我的代碼：

變壓器：

<?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, 
     ]; 
    } 
} 

路線文件：

Route::get('/', function() { 

    $student = App\Models\Student::first(); 

    $response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer); 

    return response()->json([$response]); 

}); 

返回此：

[ 
    { } 
] 

如果我dd()，像這樣：

Route::get('/', function() { 

    $student = App\Models\Student::first(); 

    $response = new League\Fractal\Resource\Item($student, new App\Transformers\Models\StudentTransformer); 

    dd($response); 

}); 

我得到以下，沒有明顯的轉變做出

Item {#299 ▼ 
    #data: Student {#305 ▼ 
    #fillable: array:10 [▼ 
     0 => "name" 
     1 => "birth_date"

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

    } 
} 

任何想法，我在這裏失蹤？

Answer 1

我的實現如下：

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()); 

}); 

你必須創建一個\League\Fractal\Manager實例和一個串行分配到它。經理會將數據返回給數組或其他人。

在fractal page，有更多的細節。

Answer 2

我沒有在項目中使用Factral，但我認爲你需要做類似的事情。

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()); 

});
