てくてくあるく

WordPress の テーマ とか プラグイン に ついて 勉強しています

cakePHP 3 を 直接 触って 覚えてみることにした No.4

わかってしまえば 大した事ないのですが 前回から ず〜と 悩んでました…

やっと ログイン画面を 作成することができたので 忘れないように メモしておきます

テーブル作成

管理者用 の ユーザ を 保存するための テーブル を 作成します
ユーザ名 メールアドレス パスワード を 1セット として Admins を作成します

bin/cake bake migration CreateAdmins username:string:unique email:string:unique password:string created modified -p Admin
bin/cake migrations migrate -p Admin

コントローラー

コントローラー は Users として 作成します

plugins/Admin/src/Controller/UsersController.php

<?php
namespace Admin\Controller;

use Admin\Controller\AppController;

/**
 * Users Controller
 *
 * @property \Admin\Model\Table\AdminTable $Admins

    {
        $this->set( 'title_for_layout', __( 'Admin List' ) );
        $this->loadModel( 'Admin.Admins' );

        $admins = $this->paginate( $this->Admins );

        $this->set( compact( 'admins' ) );
        $this->set( '_serialize', ['admins'] );
    }

     * Logout method
     */
    public function logout()
    {
        return $this->redirect( $this->Auth->logout() );

モデル

モデル は bake で 作ってしまいましょう
DB を 元に 作ってくれるので 非常に便利です!!

bin/cake bake model Admins -p Admin

単純に 作成しただけでは password は ハッシュ化されないので Entity という 機能を使って DB に 入れる直前に ハッシュ化 されるようにします

省略した形で書きます

plugins/Admin/src/Model/Entity/Admin.php

~ bake された 記述 ~
use Cake\Auth\DefaultPasswordHasher;

class Admin extends Entity
{
    ~ bake された 記述 ~

    protected function _setPassword( $password )
    {
          return ( new DefaultPasswordHasher )->hash( $password );
    }
}

ビュー部分は Bootstrap の コーディングが必要ですので ソースを ガシガシ 載せます!!

ユーザ登録

http://localhost:8888/my_app_name/admin/users/add から 最初のユーザを 登録します

これで ハッシュ化された パスワードが 生成されます

ログイン認証

/plugins/Admin/src/Controller/AppController.php

class AppController extends BaseController
{

    public function initialize()
    {
        parent::initialize();

        $this->loadComponent( 'Auth', [
            'loginRedirect' => [
                'controller' => 'Pages',
                'action'     => 'display',
                                'front-page',
            ],
            'logoutRedirect' => [
                'controller' => 'Users',
                'action'     => 'login',
            ],
            'loginAction' => [
                'controller' => 'Users',
                'action'     => 'login',
            ],
            'authenticate' => [
                'Form' => [
                    'userModel' => 'Admin.Admins',
                ]
            ],
            'sessionKey' => 'Auth.Admin',
        ] );

    }

    ~ bake された 記述 ~
}

これで ログイン ログアウト が できるようになりました

UsersController で $this->loadModel( ‘Admin.Admins’ ); の Admin. が わからなくて パスワードが ハッシュ化されなくて ずっと悩んでました…

手探りで 勉強しているので 間違っていたら ご指摘いただけると助かります!!
