目標
- ソリューションの機能について理解する。
- ソリューション内での Apps Script サービスの役割を理解する。
- スクリプトを設定します。
- スクリプトを実行します。
このソリューションについて
エンドツーエンドの社外活動の登録システムを作成します。このソリューションでは、従業員がアクティビティの設定を入力できるフォームを作成し、従業員の設定をアクティビティ スケジュールと照合します。
仕組み
このスクリプトは、Google スプレッドシートのアクティビティ スケジュールを使用して、従業員がアクティビティの設定を選択できる Google フォームを作成します。回答が届くと、スクリプトは従業員の希望を各アクティビティのスケジュールと容量と照合します。一致は 2 つの新しいシートに表示されます。1 つは従業員別に、もう 1 つはアクティビティ別に整理されています。
Apps Script サービス
このソリューションでは、次のサービスを使用します。
- スプレッドシート サービス - アクティビティのスケジュールとフォームの回答を保持し、アクティビティを社員に割り当てます。
- フォーム サービス - 社員がアクティビティの設定を入力するためのフォームを作成します。
- ユーティリティ サービス - 文字列と日付をフォーマットします。
前提条件
このサンプルを使用するには、次の前提条件を満たしている必要があります。
- Google アカウント（Google Workspace アカウントの場合、管理者の承認が必要となる可能性があります）。
- インターネットに接続できるウェブブラウザ。
スクリプトを設定する
次のボタンをクリックして、社外活動の登録サンプル スプレッドシートのコピーを作成します。このソリューションの Apps Script プロジェクトがスプレッドシートに添付されています。
コピーを作成
スクリプトを実行する
- コピーしたスプレッドシートで、[アクティビティ] > [フォームを作成] をクリックします。このカスタム メニューが表示されない場合は、ページを更新してください。
プロンプトが表示されたら、スクリプトを承認します。OAuth 同意画面に [このアプリは確認されていません] という警告が表示された場合は、[詳細] > [{プロジェクト名} に移動（安全でない）] を選択して続行します。
[アクティビティ] > [フォームを作成] をもう一度クリックします。
テスト レスポンスを生成するには、[アクティビティ] > [テストデータを生成] をクリックします。
フォームを自分でテストするには、[ツール] > [フォームを管理] > [実際のフォームを開く] をクリックします。
フォームに記入し、[送信] をクリックします。
スプレッドシートで、[アクティビティ] > [アクティビティを割り当てる] をクリックします。
2 つの新しいシート（アクティビティ（個人別）とアクティビティ名簿）を確認します。
