authorize, authenticate, loginRedirect, logoutRedirect, authError
$this->request->session()->destroy();

### login.ctpを作成

<div class="users form">
<?= $this->Flash->render('auth') ?>
<?= $this->Form->create() ?>
	<fieldset>
		<legend>アカウント名とパスワードを入力して下さい。</legend>
		<?= $this->Form->input('username') ?>
		<?= $this->Form->input('password') ?>
	<fieldset>
<?= $this->Form->button(__('Login')); ?>
<?= $this->Form->end() ?>
</div>

AuctionBaseController.phpを作成し、継承させる
なるほどー

$ php composer.phar create-project –prefer-dist cakephp/app:3.* auction

bin/cake bake migration CreateUsers username:string[100] password:string[100] role:string[20]
bin/cake bake migration CreateBiditems user_id:integer name:string[100] finished:boolean endtime:datetime created
bin/cake bake migration CreateBidinfo bititem_id:integer user_id:integer price:integer created
bin/cake bake migration CreateBidrequests biditem_id:integer user_id:integer price:integer created
bin/cake bake migration CreateBidmessages bidinfo_id:integer user_id:integer message:text created
bin/cake migrations migrate
bin/cake bake all users
bin/cake bake all biditems
bin/cake bake all bidinfo
bin/cake bake all bidrequests
bin/cake bake all bidmessages

controller

$this->loadComponent('Paginator');

PeopleController.php

	public $paginate = [
		'limit' => 5,
		'sort' => 'id',
		'direction' => 'asc',
		'contain' => ['Messages'],
	];

	public function initialize(){
		parent::initialize();
		$this->loadComponent('Paginator');
	}

	public function index(){
		$data = $this->paginate($this->People);
		$this->set('data', $data);
	}

template

<p>This is People table records.</p>
<table>
<thead><tr>
	<th>id</th><th>name</th><th>mail</th><th>age</th><th>message</th>
</tr></thead>
<?php foreach($data->toArray() as $obj): ?>
<tr>
	<td><?=h($obj->id) ?></td>
	<td><a href="<?=$this->Url->build(["controller"=>"People", "action"=>"edit"]); ?>?id=<?=$obj->id ?>"><?=h($obj->name) ?></a></td>
	<td><?=h($obj->mail) ?></td>
	<td><?=h($obj->age) ?></td>
	<td><?php foreach($obj->messages as $item): ?>
	"<?=h($item->message) ?>"<br>
	<?php endforeach; ?></td>
	<td><a href="<?=$this->Url->build(["controller"=>"People", "action"=>"delete"]); ?>?id=<?=$obj->id ?>">delete</a></td>
</tr>
<?php endforeach; ?>
</table>
<div class="paginator">
	<ul class="pagination">
		<?=$this->Paginator->first(' |<< ' . '最初へ') ?>
		<?=$this->Paginator->prev(' << ' . '前へ') ?>
		<?=$this->Paginator->next('次へ ' . ' >> ') ?>
		<?=$this->Paginator->last('最後へ' . ' >>| ') ?>
	</ul>
</div>

custom finderを利用することもできる

なるほど、とりあえずOK 次に行こう

$this->Html->doctype(document type)
$this->Html->charset(charset)
$this->Html->css(file name)
$this->Html->style()
$this->Html->script()
$this->Html->scriptStart()
$this->Html->scriptEnd()
$this->Html->link()
$this->Html->image()
$this->Html->script()
$this->Html->tableHeaders()
$this->Html->tableCells()

<table>
<?=$this->Html->tableHeaders(["title", "name", "mail"],
	["style"=>["background:#006; color:white"]]) ?>
<?=$this->Html->tableCells([["this is sample", "taro", "taro@yamada"],["this is sample", "taro", "taro@yamada"],["this is sample", "taro", "taro@yamada"]], ['style'=>['background:#ccf']], ['style'=>['background:#ccf']]) ?>
</table>

$this->Html->nestedList()

アクションの指定、クエリパラメータの指定、拡張子の指定などもUrlBuilderで指定できる

### Textヘルパー

<?=$this->Text->autoLinkUrls('http://google.com') ?>
<?=$this->Text->autoLinkEmails('hoge@gmail.com') ?>
<?=$this->Text->autoParagraph('one\ntwo\nthree') ?>

Numberヘルパー

<p>金額は、<?=$this->Number->currency(1234567, 'JPY') ?>です。</p>
<p>2桁で表すと、<?=$this->Number->precision(1234.56789, 2) ?>です。</p>
<p>2桁で表すと、<?=$this->Number->toPercentage(0.12345, 2, ['multiply'=>true]) ?>です。</p>

OK、大分いいところまで来た気がする
