Question

我在表之间有联接，然后我希望更改2个值并使用此联接保存每个记录。

foreach ($data as $datas) {
     $datas->dealerCode = $datas->dealer;
     $datas->owner = 'K';

     $datas->save();
}

我能够获取集合中的记录（$data），但似乎无法保存。我想要更新的字段可以在模型中填写。

我错过了什么？

感谢。

$ datas is;

消费者模型;

protected $fillable = [
    'salutation',
    'firstName',
    'lastName',
    'email',
    'postal',
    'phone',
    'address1',
    'address2',
    'city',
    'province',
    'owner',
];

顺便说一句，这就是它在mySql中的工作方式;

update consumers c
join owners o
on c.email = o.email
set c.owner = 'K'

以下是我的控制器的完整功能;

public function setOwner()
{
        $data = Consumer::join('owners', 'consumers.email', '=', 'owners.email')
            ->where('consumers.eventCode', '=', 'Test')->get();

    foreach ($data as $datas) {
        $obj = Consumer::find($datas['id']);
        //$obj = empty($obj) ? new Consumer : $obj;
        // $obj = new Consumer;
        $obj->dealerCode = $datas['dealer'];
        $obj->owner = 'K';
        $obj->save();
    }

}

Answer 1

你必须在循环的每一步中创建新对象

foreach ($data as $datas) {
        $datas = new Datas();
        $datas->dealerCode = $datas->dealer;
        $datas->owner = 'K';
        $datas->save();
    }

Answer 2

foreach ($data as &$datas) {
        $datas->dealerCode = $datas->dealer;
        $datas->owner = 'K';

        $datas->save();
    }

刚刚通过＆amp;在$ database之前。 $ data将被更新。

Answer 3

试试这段代码： -

foreach ($data as $datas) {
     $obj = Consumer::find($datas['id']);
     //$obj = empty($obj) ? new Consumer : $obj;
     // $obj = new Consumer;
     $obj->dealerCode = $datas['dealer'];
     $obj->owner = 'K';
     $obj->save();
}

希望它对您有用：）

为什么这个foreach不能保存？ Laravel 5
