270. 270 270 まず最初にすることは MVC を捨てること

     $inputPort, Request $request) { $name = $request->input('name'); $roleId = $request->input('roleId'); $inputData = new UserCreateInputData($name, $roleId); $inputPort->handle($inputData); ... 戻り値を無くす } }

     $inputPort, Request $request) { $name = $request->input('name'); $roleId = $request->input('roleId'); $inputData = new UserCreateInputData($name, $roleId); $inputPort->handle($inputData); ... 戻り値を無くす } }

273. 273 class UserController extends BaseController { public function create( UserCreateInputPortInterface

     $inputPort, Request $request) { $name = $request->input('name'); $roleId = $request->input('roleId'); $inputData = new UserCreateInputData($name, $roleId); $inputPort->handle($inputData); ... 戻り値を無くす } }

274. 274 class UserController extends BaseController { public function create( UserCreateInputPortInterface

     $inputPort, Request $request) { $name = $request->input('name'); $roleId = $request->input('roleId'); $inputData = new UserCreateInputData($name, $roleId); $inputPort->handle($inputData); ... 戻り値を無くす } }

275. 275 class UserCreatePresenter implements UserCreateOutputPortInterface { public function output(UserCreateOutputData $outputData)

     { ... どうにかしてビューを描画する } }

276. 276 class UserCreatePresenter implements UserCreateOutputPortInterface { public function output(UserCreateOutputData $outputData)

     { ... どうにかしてビューを描画する } } こっちの方がむしろ Classic MVC に近い

277. 277 戻り値がなくなる
