Lograge / lograge-sql kann verwendet werden, um Rails-Protokolle und mehrzeilige Protokolle wie z. B. Ausführungs-SQL in einem Format wie Json auszugeben, damit die Protokolle leicht lesbar sind.
lograge lograge ist ein Juwel, das eine einzelne Protokollzeile (Beispiel: json) ausgeben kann, indem nur die erforderlichen Informationen für das mehrzeilige Protokoll des grundlegenden Loggers von Rails verwendet werden. https://github.com/roidrage/lograge

Das Verbindungsergebnis der Root-Analyse wird in einer Zeile in der letzten Zeile ausgegeben
** Fügen Sie Folgendes hinzu, wenn Sie im Json-Format ausgeben möchten **
config/environments/develpment.rb
config.lograge.formatter = Lograge::Formatters::Json.new
Das Ergebnis der Verbindung zu Root wird im Json-Format angezeigt.
