モデルの作成

データベースができたら次はモデルの作成を行う

bin/cake bake model Users
bin/cake bake model Articles

# root/src/src/Modelの中に出来る

ModelディレクトリにはBehavior、Entity、Tableディレクトリがある

User.php

// src/src/Model/Entity

<?php
declare(strict_types=1);

namespace App\Model\Entity;

use Cake\ORM\Entity;

/**
 * User Entity
 *
 * @property int $id
 * @property string $email
 * @property string $password
 * @property \Cake\I18n\FrozenTime $created
 * @property \Cake\I18n\FrozenTime $modified
 *
 * @property \App\Model\Entity\Article[] $articles
 */
class User extends Entity
{
    /**
     * Fields that can be mass assigned using newEntity() or patchEntity().
     *
     * Note that when '*' is set to true, this allows all unspecified fields to
     * be mass assigned. For security purposes, it is advised to set '*' to false
     * (or remove it), and explicitly make individual fields accessible as needed.
     *
     * @var array<string, bool>
     */
    protected $_accessible = [
        'email' => true,
        'password' => true,
        'created' => true,
        'modified' => true,
        'articles' => true,
    ];

    /**
     * Fields that are excluded from JSON versions of the entity.
     *
     * @var array<string>
     */
    protected $_hidden = [
        'password',
    ];
}

エンティティは個々のインスタンスを表す
$_accessibleは一括代入できるかを制御している
$_hiddenはJSON等に変換した際に非表示にするフィールドを指定している

UsersTable.php

// src/src/Model/Table

<?php
declare(strict_types=1);

namespace App\Model\Table;

use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;

/**

 *

 *

 * @method \App\Model\Entity\User[]|\Cake\Datasource\ResultSetInterface deleteManyOrFail(iterable $entities, $options = [])
 *
 * @mixin \Cake\ORM\Behavior\TimestampBehavior
 */
class UsersTable extends Table
{
    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config): void
    {
        parent::initialize($config);

        $this->setTable('users');
        $this->setDisplayField('id');
        $this->setPrimaryKey('id');

        $this->addBehavior('Timestamp');

        $this->hasMany('Articles', [
            'foreignKey' => 'user_id',
        ]);
    }

    /**
     * Default validation rules.
     *
     * @param \Cake\Validation\Validator $validator Validator instance.
     * @return \Cake\Validation\Validator
     */

    {
        $validator
            ->email('email')
            ->requirePresence('email', 'create')
            ->notEmptyString('email');

        $validator
            ->scalar('password')
            ->maxLength('password', 255)
            ->requirePresence('password', 'create')
            ->notEmptyString('password');

        return $validator;
    }

    /**
     * Returns a rules checker object that will be used for validating
     * application integrity.
     *
     * @param \Cake\ORM\RulesChecker $rules The rules object to be modified.
     * @return \Cake\ORM\RulesChecker
     */
    public function buildRules(RulesChecker $rules): RulesChecker
    {
        $rules->add($rules->isUnique(['email']), ['errorField' => 'email']);

        return $rules;
    }
}

テーブルはデータを操作するための主要なインターフェースを提供する
initalizeメソッドはテーブル名、主キー、表示フィールドの設定
ビヘイビアや関連するテーブルとの関連付けを行う

次はコントローラを作る
