在Laravel 5.2中，我会让它尽可能的干净:

public function saveContact(Request $request, Contact $contact)
{
   $create = $contact->create($request->all());
   return response()->json($create->id,  201);
}

For anyone who also likes how Jeffrey Way uses Model::create() in his Laracasts 5 tutorials, where he just sends the Request straight into the database without explicitly setting each field in the controller, and using the model's $fillable for mass assignment (very important, for anyone new and using this way): I read a lot of people using insertGetId() but unfortunately this does not respect the $fillable whitelist so you'll get errors with it trying to insert _token and anything that isn't a field in the database, end up setting things you want to filter, etc. That bummed me out, because I want to use mass assignment and overall write less code when possible. Fortunately Eloquent's create method just wraps the save method (what @xdazz cited above), so you can still pull the last created ID...

public function store() {

    $input = Request::all();
    $id = Company::create($input)->id;

    return redirect('company/'.$id);
}

这在laravel 4.2中是可行的

$id = User::insertGetId([
    'username' => Input::get('username'),
    'password' => Hash::make('password'),
    'active'   => 0
]);

对于Laravel，如果你插入一个新记录并调用$data->save()，这个函数执行一个insert查询并返回主键值(默认为id)。

你可以使用以下代码:

if($data->save()) {
    return Response::json(array('status' => 1, 'primary_id'=>$data->id), 200);
}

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

为劳拉***

首先创建一个对象，然后为该对象设置属性值，然后保存对象记录，然后获取最后插入的id。如

$user = new User();        

$user->name = 'John';  

$user->save();

//现在获取最后插入的id

$insertedId = $user->id;

echo $insertedId ;
