請求數據 { "exam_id": 10, "exam_scores": [ { "student_id": 1, "subject_id": 1, "marks": 50, }, { "student_id": 1, "subject_id": 2, "marks": 70, }, { "student_id": 1, "subject_id": 3, "marks": 80, } ], }如果student_id和subject_id是唯一的復合鍵，如何使用規則方法為復合鍵制作驗證程序，該方法接受我嘗試過的數據數組（），但它無法按預期工作。$validator = Validator::make(request()->all(), [ "exam_id"=> "required|integer", "exam_scores"=> "required|array", 'exam_scores.*.student_id' => [ Rule::unique('results')->where(function ($query) { return $query ->whereStudent_idAndSubject_id(request()->get('exam_scores.*.student_id'),request()->get('exam_scores.*.subject_id')) }) ],]);以下請求不應驗證數據。但它驗證成功。{ "exam_id": 10, "exam_scores": [ { "student_id": 1, "subject_id": 1, "marks": 50, }, { "student_id": 1, "subject_id": 1, "marks": 70, } ], }以下請求使用預期的單個對象exam_scores成功驗證數據。 { "exam_id": 10, "exam_scores": { "student_id": 1, "subject_id": 1, "marks": 50, } }$validator = Validator::make(request()->all(), [ "exam_id"=> "required|integer", "exam_scores"=> "required|array", 'exam_scores.student_id' => [ Rule::unique('results')->where(function ($query) { return $query ->whereStudent_idAndSubject_id(request()->get('exam_scores.student_id'),request()->get('exam_scores.subject_id')) })],]);

在搜索了許多博客，教程，當然還有laravel文檔之后，我得到了一些解決我的問題是博客鏈接的東西。這不是我真正想要的，但它清楚地說明了我必須做什么的概念。這個家伙拯救了我的一天。
下面是一個示例。
namespace App\Http\Requests;
use App\Http\Requests\Request;
class OrderRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
$rules = [
'name' => 'required|max:255',
];
foreach ($this->request->get('items') as $key => $val) {
$rules['items.' . $key] = 'required|max:10';
}
return $rules;
}
public function messages()
{
$messages = [];
foreach ($this->request->get('items') as $key => $val) {
$messages['items.' . $key . '.max'] = 'The field labeled "Book Title ' . $key . '" must be less than :max characters.';
}
return $messages;
}
}
解決方案非常簡單易行。
