laravel 5.6批量插入json数据 [英] laravel 5.6 bulk inserting json data

问题描述

我正在尝试构建一个用于存储和检索MCQ考试论文的API.我正在使用laravel资源类发送句柄Json数据.我需要在单个查询中将40条记录插入MySQL数据库，而无需使用多维数组.有没有可用的方法?

I am trying to build an API to store and retrieve MCQ exam papers. I am using laravel resource class to send handle Json data. I need to insert 40 records into MySQL database in a single query without using multi dimensional arrays. Is there any method available?

从前端采样数据:

{
"data":[
    {
    "paper_id":"5",
    "question_no":"2",
    "question":"test insert code",
    "answer1":"answer1",
    "answer2":"answer2 ",
    "answer3":"answer3 ",
    "answer4":"Answer4 ",
    "answerC":"Correct Answer",
    "knowarea":"who knows!"

    },

    {
        "paper_id":"5",
        "question_no":"3",
        "question":"test insert code",
        "answer1":"answer1",
        "answer2":"answer2 ",
        "answer3":"answer3 ",
        "answer4":"Answer4 ",
        "answerC":"Correct Answer",
        "knowarea":"who knows!"

    },

    {
        "paper_id":"5",
        "question_no":"4",
        "question":"test insert code",
        "answer1":"answer1",
        "answer2":"answer2 ",
        "answer3":"answer3 ",
        "answer4":"Answer4 ",
        "answerC":"Correct Answer",
        "knowarea":"who knows!"

    },

    {
        "paper_id":"5",
        "question_no":"5",
        "question":"test insert code",
        "aanswer1":"answer1",
        "answer2":"answer2 ",
        "answer3":"answer3 ",
        "answer4":"Answer4 ",
        "answerC":"Correct Answer",
        "knowarea":"who knows!"

    }
]

}`

前端发送40个此类对象，我需要将其批量插入到我的数据库中. 下面的代码是我的控制器存储功能，

The front end send 40 such objects i need to bulk insert them into my database. The below code is my controller store function,

`   $paper->paper_id = $request->input('paper_id');
    $paper->question_no = $request->input('question_no');
    $paper->question = $request->input('question');
    $paper->answer1 = $request->input('answer1');
    $paper->answer2 = $request->input('answer2');
    $paper->answer3 = $request->input('answer3');
    $paper->answer4 = $request->input('answer4');
    $paper->answerC = $request->input('answerC');
    $paper->knowarea = $request->input('knowarea');

    if($paper->save())
    {
        return new ExamPaperResource($paper);
    }

批量插入数据有哪些选择?

推荐答案

此代码对我有用.它插入了全部40条记录，没有问题.

This code works for me. It inserted all 40 records with no problems.

$array = $request->all();
    foreach($array["data"] as $row)
    {
        Exam_Paper::create(['paper_id'      => $row["paper_id"],
                            'question_no'   => $row["question_no"],
                            'question'      => $row["question"],
                            'answer1'       => $row["answer1"],
                            'answer2'       => $row["answer2"],
                            'answer3'       => $row["answer3"],
                            'answer4'       => $row["answer4"],
                            'answerC'       => $row["answerC"],
                            'knowarea'      => $row["knowarea"],
        ]);

    }
