最短的方法可能是在模型上调用refresh():

public function create(array $data): MyModel
{
    $myModel = new MyModel($dataArray);
    $myModel->saveOrFail();
    return $myModel->refresh();
}

下面是我们如何在Laravel 4中获得最后一个插入id

public function store()
{
    $input = Input::all();

    $validation = Validator::make($input, user::$rules);

    if ($validation->passes())
    {

     $user= $this->user->create(array(
            'name'              => Input::get('name'),
            'email'             => Input::get('email'),
            'password'          => Hash::make(Input::get('password')),
        ));
        $lastInsertedId= $user->id; //get last inserted record's user id value
        $userId= array('user_id'=>$lastInsertedId); //put this value equal to datatable column name where it will be saved
        $user->update($userId); //update newly created record by storing the value of last inserted id
            return Redirect::route('users.index');
        }
    return Redirect::route('users.create')->withInput()->withErrors($validation)->with('message', 'There were validation errors.');
    }

这里有一个例子:

public static function saveTutorial(){

    $data = Input::all();

    $Tut = new Tutorial;
    $Tut->title = $data['title'];
    $Tut->tutorial = $data['tutorial'];   
    $Tut->save();
    $LastInsertId = $Tut->id;

    return Response::json(array('success' => true,'last_id'=>$LastInsertId), 200);
}

获取数据库中最后插入的id 你可以使用

$data = new YourModelName;
$data->name = 'Some Value';
$data->email = 'abc@mail.com';
$data->save();
$lastInsertedId = $data->id;

这里$lastInsertedId会给你最后插入的自动增量id。

保存模型后，初始化实例的id为:

$report = new Report();
$report->user_id = $request->user_id;
$report->patient_id = $request->patient_id;
$report->diseases_id = $request->modality;
$isReportCreated = $report->save();
return $report->id;  // this will return the saved report id

虽然这个问题有点过时了。我的快速解决方案是这样的:

$last_entry = Model::latest()->first();

但我猜它很容易受到频繁使用的数据库的竞争条件的影响。
