■カスタマイズ: 新着情報管理をもとに独自の記事管理を作成

既存機能の「新着情報管理」をもとに、独自の記事管理を作成してみる
独自に作成したテーブルには専用のプレフィックスを付けておく方が管理しやすいか。contactも含めて考える

■調査メモ@ORM\DiscriminatorColumn(name="discriminator_type", type="string", length=255)


EC-CUBE4のDBのそれぞれのテーブルにあるdiscriminator_typeとは何なのか - Qiita
https://qiita.com/okazy/items/974d8e07b0dbd50b9c6a
Entityを継承して拡張するときに利用されるらしい
ECCubeでは以下のアノテーションを指定すると、discriminator_type列にクラス名が小文字になった文字列が入る
現状それ以上は気にしなくていいか

@ORM\InheritanceType("SINGLE_TABLE")


Doctrine2のInheritanceMapping | QUARTETCOM TECH BLOG
https://tech.quartetcom.co.jp/2015/08/24/doctorine2-inheritance-mapping/
Single Table Inheritance は、全ての階層構造を一つのテーブルで表現したもの
Class Table Inheritance は、複数テーブルで継承関係を表現したもの
ECCubeではすべてのテーブルで SINGLE_TABLE が指定されいているみたい

@ORM\HasLifecycleCallbacks()


データーベースと Doctrine | SymDoc - PHP フレームワーク Symfony3 日本語ドキュメント Wiki
http://symdoc.kwalk.jp/doc/book/doctrine
エンティティが INSERT や UPDATE、DELETE される直前または、直後に、アクションを実行することができる
例えば「データを登録する際に、自動で特定のメソッドが実行されるようにする」のような処理ができる
ECCubeではすべてのテーブルに指定されいているみたい
