Module: Sequel::Database::AppydaysLogger

Defined in:
lib/appydays/loggable/sequel_logger.rb

Overview

Helpers for the Appydays Sequel logger. Very long messages may end up getting logged; the logger will truncate anything longer than truncate_messages_over, with truncation_context number of chars at the beginning and at the end.

If a message is truncated, the full message is logged at log_full_message_level (default :debug). Use nil to disable the full message logging.
