php - Insert Collection to saveMany Eloquent

Question

我有一个充满模型的集合，我如何将它们放入关系的 saveMany 方法中？我知道它一定是一个数组，但是当我执行 $collection->toArray() 时，它们不再是 Eloquent 模型了。

public function uploadAndGetModels($messageId, array $attachments)
{
    $models = new Collection();
    $attachments = new Collection($attachments);
    $attachments->each(function (UploadedFile $attachment) use ($messageId, $models) {
        $identifier = $this->uploader->makeIdentifier($attachment->getClientOriginalExtension());
        $this->uploader->uploadImage($attachment, "attachments/{$identifier}");
        $model = new Attachment(array('message_id' => $messageId, 'path' => $identifier));
        $models->push($model);
    });

    return $models;
}

$models 的结果是一个包含Attachment 模型的Collection。

if ($request->hasFile('attachments')) {
    $attachments = $attachmentRepository->uploadAndGetModels($message->id, $request->file('attachments'));
    $message->attachments()->saveMany($attachments);
}

我该如何解决这个问题？

Answer 1

Collection 类有一个 all() 方法，它以模型数组的形式返回集合中的所有项目。

考虑到这一点，这应该可行...

$message->attachments()->saveMany($attachments->all());
