关于laravel:laravel模型的一些特性

1模型复制

replicate办法能够保留一个新的模型正本,例如:此处的$user与$NewUser,$shipping与$NewShipping的根本数据是统一的$user = \App\User::find(1);$newUser = $user->replicate();$newUser->save();$shipping = App\Address::create([    'type' => 'shipping',    'line_1' => '123 Example Street',    'city' => 'Victorville',    'state' => 'CA',    'postcode' => '90001',]);$NewShipping=$shipping->replicate();

2模型校验

is办法能够校验两个模型实例是否领有雷同的主键,表，数据库连贯$user=\App\User::find(1);$sameUser=\App\User::find(1);$diffUser=\App\User::find(2);$user->is($sameUser);//true$user->is($diffUser);//false
