Laravel 分页和合并

Question

在我的 Laravel 项目中，我在代码的前 3 行中获取数据并将其组合起来并在我的视图页面中使用它，但我使用完整的数据 ->get();我用 拍摄后分页。我的目标是使用控制器中此函数的分页功能从 3 个不同类别中提取数据，并将它们均衡为单个变量。

我的控制器功能

    public function allApprovedQuestions(Request $request)
{
    $csQuestions = QuestionCheck::where('QUESTION_TYPE', 1)->with('questionsCS')->get();

    $daQuestions = QuestionCheck::where('QUESTION_TYPE', 2)->with('questionsDA')->get();

    $dyQuestions = QuestionCheck::where('QUESTION_TYPE', 3)->with('questionsDY')->get();

    $csCount = $csQuestions->count();
    $daCount = $daQuestions->count();
    $dyCount = $dyQuestions->count();

    $nonPagiinatedQuestions = collect();

    foreach ($csQuestions as $csQuestion) {
        $nonPagiinatedQuestions->push((object)[
            'id' => $csQuestion->questionsCS->SID,
            'question' => $csQuestion->questionsCS->SORU,
            'type' => $csQuestion->QUESTION_TYPE,
        ]);
    }

    foreach ($daQuestions as $daQuestion) {
        $nonPagiinatedQuestions->push((object)[
            'id' => $daQuestion->questionsDA->SID,
            'question' => $daQuestion->SORU1,
            'type' => $daQuestion->QUESTION_TYPE,
        ]);
    }

    foreach ($dyQuestions as $dyQuestion) {
        $nonPagiinatedQuestions->push((object)[
            'id' => $dyQuestion->questionsDY->SID,
            'question' => $dyQuestion->questionsDY->SORU,
            'type' => $dyQuestion->QUESTION_TYPE,
        ]);
    }

    $perPage = 2;
    $currentPage = request()->input('page', 1);
    $currentPageItems = $nonPagiinatedQuestions->slice(($currentPage - 1) * $perPage, $perPage)->all();
    $questions = new LengthAwarePaginator($currentPageItems, $nonPagiinatedQuestions->count(), $perPage, $currentPage);

    return view('content.approved-questions', compact('questions', 'csCount', 'daCount', 'dyCount'));
}

Answer 1

您需要将

whereIn

子句与一组

with

语句一起使用，然后对其进行分页。

$csQuestions = QuestionCheck::whereIn('QUESTION_TYPE', [1, 2, 3])->with([
    'questionsCS',
    'questionsDA',
    'questionsDY',
])->paginate();
