最近、Discourse ダッシュボードレポートと類似のデータを返すが、期間別に集計可能なデータエクスプローラークエリを作成しました。例えば、指定された開始日と終了日の間に作成されたトピックの数を示すが、集計を日次ではなく週次で行うといったものです。
クエリのパラメータは以下のルールで設定されます：
クエリパラメータ：query_interval（Postgres のインターバル、例：‘1 day’、‘7 days’、‘1 week’、‘1 month’）、start_date（‘yyyy-mm-dd’）、end_date（‘yyyy-mm-dd’）、category_ids（カンマ区切りのカテゴリ ID リスト、デフォルトは -1）、include_subcategories（ブーリアン、デフォルトは true）。指定された開始日と終了日の間に作成された投稿の数を返します。結果はクエリインターバルでグループ化されます。category_ids リストに -1 が含まれている場合、すべてのカテゴリの結果が返されます。
