自定义验证不调用 passes() 函数

Question

我正在尝试进行验证，以按照 Custom Validation Rules 中的步骤检查数组中是否至少提供了一项 Routes.php

Route::middleware(['auth:api', 'bindings'])->group(function () {
  Route::prefix('api')->group(function () {
    Route::apiResources([
      'exam-papers/{examPaper}/questions' => ExamPaperQuestionsController::class
    ]);
  });
});

ValidateArrayElementRule.php


namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class ValidateArrayElementRule implements Rule
{
  public function __construct()
  {
    //
  }

  public function passes($attribute, $value)
  {
    echo "there";
    return count($value) > 0;
  }

  public function message()
  {
    return 'At least one element is required!';
  }
}

ExamPaperQuestionsController.php

 public function store(ExamPaperQuestionStoreRequest $request, ExamPaper $examPaper)
 {
    return response()->json([])->setStatusCode(201);
 }

在我的测试文件中我有

  public function error_422_if_no_questions_provided()
  {
    Permission::factory()->state(['name' => 'create exam paper question'])->create();
    $this->user->givePermissionTo('create exam paper question');
    $this->actingAs($this->user, 'api')
      ->postJson('/api/exam-papers/' . $this->examPaper->id . '/questions', [])
      ->assertStatus(422);

  }

ExamPaperQuestionStoreRequest.php


class ExamPaperQuestionStoreRequest extends FormRequest
{
  /**
   * Determine if the user is authorized to make this request.
   *
   * @return bool
   */
  public function authorize()
  {
    return auth()->user()->can('create exam paper question');
  }

  /**
   * Get the validation rules that apply to the request.
   *
   * @return array
   */
  public function rules()
  {
    echo "HERE";
    return [
      'questions' => [new ValidateArrayElementRule],
      'questions.*.description' => 'required'
    ];
  }


}

测试失败

Expected status code 422 but received 201.

我可以看到记录了文本“HERE”，但没有记录“there”。为什么我的验证 passes() 函数没有被调用？

Answer 1

为什么不在验证中使用简单方法？ :

$request->validate([
    'title' => 'required|min:5|max:20',
    'detail' => 'required',
    'cat_image' => 'required',
]);

Answer 2

假设如果您的请求包含空值，那么它不会调用自定义验证。所以你必须添加 required filed 以确保请求有 key questions

'questions' => ["required",new ValidateArrayElementRule]

Incase 问题是可选的，如果输入，则至少需要两到三个项目，然后您可以在验证时使用 required。

默认laravel支持数组最小值

'questions' => ["required","array","min:1"]

自定义验证不调用 passes() 函数

Custom validation not calling the passes() function

php

laravel
