Lets say you’re developing a product and selling in the market and then you’re providing a service for the product. Laravelフレームワークを使用した開発経験と知識がある程度積むことが出来ましたので、身に付けたRepositoryデザインパターンとLaravelフレームワークの応用をみなさんに共有したいと思います。, これは高度なデザインパータンですので初心者のエンジニアさんはあまり気にしないかも知れませんが、IT会社で勤務経験のあるインターンシップは必ずトレーナーから教えてもらったかと思います。Repositoryデザインパターンは.NET、Java、 PHP等多くの言語・フレームワークを使っており、ウェブサイト、サービス、アプリケーションからモバイルアプリまで幅広く使用されています。, RepositoryデザインパターンはBusiness LogicとData Sourceの中間クラスにあるものです。この中間クラスにあるオブジェクトはをRepositoryと呼ばれます。そして、 Business LogicとData Source をお互いに呼び出し合うために、Interface経由で実施されます。, これによってアウトプットデータを標準化させ、ビジネスロジックとデーターアクセスロジックを分けて処理することが出来ます。また、ビジネスロジックもデータソースの処理に関係なく、異なるの処理を行います（その逆も同じです）。この分割処理の目的はそれぞれのパーツを自己分担することが出来ます。こうする事でソースの構築が綺麗になり、保守しやすくなります。, Laravelでは、リポジトリはモデルとコントローラ間の「ブリッジ」として機能し、データクエリの処理場所でもあります。, これらのクエリは、コンローラーで実装する代わりにリポジトリに入れられます。コントローラは、モデルを直接呼び出すのではなく、リポジトリを介してデータソースへのアクセス・操作します。 クエリの実行方法はリポジトリ内に隠されます。（コントローラー自体は気にする必要はありません。正しくと十分なデータが返せられれば大丈夫です）, 実際に、データの簡単なGet処理であれば、リポジトリを介してコントローラで直接呼び出すことができます。, 複雑なビジネスの場合、コントローラとリポジトリの間にService層があります。これは、コントローラーがロジック処理をService層に転送することのみを担当することを意味し、Service層はビジネスロジックが実装され、データソースに更新される場所です。, システムのほとんどはユーザーモデルがあるので、今回は例として紹介したいと思います。, UserControllerでは、データを照会するためにUserが直接呼び出されます。 ユーザーがデータのクエリ方法を変更するまで、すべてが順調に進みます。ユーザーはuser_codeでソートされ、ユーザーの詳細ページはidではなくuser_codeでクエリされます。お客様の要件に合わせてデータを照会するようにコントローラーを更新する必要があります。, これは非常に危険で無駄な操作です。 UserControllerがこのような操作を実行するだけでなく、他の多くのコントローラーでも同じことを行うことを想像してください。 非常に多くの場所のコードを更新すると、見逃したり、誤動作したりする可能性が高くなります。, したがって、今後、ロジックを追加する必要があるときはいつでも、それをリポジトリに追加するだけです。, 【Laravel入門者向け】Laravel6系+PHP7.4でMVCの流れをサクッと試す (Mac編), Laravel（API）とNuxt.jsの連携を行う【Laravel6+Nuxt.jsで作る管理画面】, CookieによるAPI経由のユーザー認証機能を作る【Laravel6とNuxt.jsで作る管理画面】, Nuxt.js+VuetifyとLaravelでCRUD機能を作る【Laravel6+Nuxt.jsで作る管理画面】, オフショア開発について知る オフショア開発とは 長期開発に最適！ラボ型開発とは オフショア開発と相性の良い案件とは 発注する案件を知る WEBシステム開発の流れ Shopifyとは ハイブリッドアプリとは AI開発 オフショア開発会社を選ぶ オフショア開発を始める流れ. I'm a full-stack developer, entrepreneur and owner of Aatman Infotech. In this video, I am going to walk you through a design pattern in Laravel where we can use Service classes to push all our business logic into that class and ensure that our Controller is very slim.

What is important is that you understand the principle behind the Repository pattern. Assume, you want to change your DB from Mysql to MongoDB or anything else. The point is, your service layer would not care about the data source, it only cares about the contract the interface promises your data layer will fulfil. http://bmf-tech.com/. ラバー・ダックというプログラミングにおける 「問題解決」の方法 デバッグの最高な技術, React Native VS Flutter アプリ開発に必要な5つの比較ポイント, データの構築、データソース、ビジネスロジックに変更が発生する場合、ソースの変更が少なく済む. With that in mind, let’s start with the definitionof the Repository pattern: Repository patternseparates the data access logic and maps it to the business entities in the business logic. Let’s go!
