如何在 laravel 验证中验证阵列数据的唯一复合键
请求数据
{
"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是唯一的复合键，如何使用规则方法为复合键制作验证程序，该方法接受我尝试过的数据数组（），但它无法按预期工作。
$validator = Validator::make(request()->all(), [
"exam_id"=> "required|integer",
"exam_scores"=> "required|array",
'exam_scores.*.student_id' => [
Rule::unique('results')->where(function ($query) {
return $query
->whereStudent_idAndSubject_id(request()->get('exam_scores.*.student_id'),request()->get('exam_scores.*.subject_id'))
})
],
]);
以下请求不应验证数据。但它验证成功。
{
"exam_id": 10,
"exam_scores": [
{
"student_id": 1,
"subject_id": 1,
"marks": 50,
},
{
"student_id": 1,
"subject_id": 1,
"marks": 70,
}
],
}
以下请求使用预期的单个对象exam_scores成功验证数据。
{
"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'))
})
],
]);

在搜索了许多博客，教程，当然还有laravel文档之后，我得到了一些解决我的问题是博客链接的东西。这不是我真正想要的，但它清楚地说明了我必须做什么的概念。这个家伙拯救了我的一天。验证动态请求值下面是一个示例。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; }}解决方案非常简单易行。
