在Laravel中更新有很多关系

Question

我建立一个小应用程序Laravel 5.5 ，其中我有两个型号： Interaction和Interaction Summary在我的Interaction我有以下关系模型：

public function meetingSummaries()
{
    return $this->hasMany('App\InteractionSummary');
}

现在要创建交互，请在控制器中使用以下代码：

$data = $request->only('user_id', 'event_type', 'schedule', 'summaries', 'type', 'venue', 'with_client');
$data['schedule'] = Carbon::parse($request->schedule)->addHours(5)->addMinutes(30)->toDateTimeString();
$meeting = [];
$meeting['user_id']= $data['user_id'];
$meeting['schedule'] = $data['schedule'];
$meeting['type'] = $data['type'];
$meeting['with_client'] = $data['with_client'];
$meeting['venue'] = $data['venue'];
$meeting['event_type'] = $data['event_type'];
$interaction = Interaction::create($meeting);
if($data['summaries'])
{
    $container = [];
    foreach($data['summaries'] as $summary)
    {
        $summary = (Object)$summary;
        if($summary->client['label'])
        {
            $container[] = new InteractionSummary([
                'company_id' => $summary->client['label'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['label'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
            }
        }
    }
    $interaction->meetingSummaries()->saveMany($container);
}

但是在更新时，我不知道该如何克服，因为在我的领域中可能会有新的或旧的关系数据。 我正在尝试这样的事情：

if($data['summaries'])
{
    $container = [];
    foreach($data['summaries'] as $summary)
    {
        $summary = (Object)$summary;
        if($summary->id)
        {
            $container[] = new InteractionSummary([
                'id' => $summary->id,
                'company_id' => $summary->client['value'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['value'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
        }
        else {
            $container[] = new InteractionSummary([
                'company_id' => $summary->client['value'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['value'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
        }
    }
    $interaction->meetingSummaries()->save($container);
}

哪个发送给我错误：

类型错误：传递给Illuminate \\ Database \\ Eloquent \\ Relations \\ HasOneOrMany :: save（）的参数1必须是Illuminate \\ Database \\ Eloquent \\ Model的实例，给定数组，在〜\\ app \\ Http \\ Controllers \\ InteractionsController.php中调用在第449行

如果我做：

$interaction->meetingSummaries()->saveMany($container);

我得到重复的新领域。

指导我如何克服这一点。 谢谢。

Answer 1

使用findOrNew()方法：

$summaryItem = InteractionSummary::findOrNew($summary->id);
$summaryItem->fill([
    'company_id' => $summary->client['value'],
    'nature' => $summary->type,
    'user_id' => $summary->mention['value'],
    'action' => $summary->action,
    'feedback' => $summary->comment
]);
