RailsCallbackLog

Logs callbacks to help with debugging.

Installation

# Gemfile
gem "rails-callback_log", group: [:development, :test]

Do not use this gem in production because it adds significant overhead.

Filtering Output

Rails has a lot of its own callbacks that you probably don't care about. If you don't want to log them, enable filtering.

# Enable filtering
export RAILS_CALLBACK_LOG_FILTER="make it so"

# Disable filtering
unset RAILS_CALLBACK_LOG_FILTER

Filtering incurs a serious performance penalty, so it is off by default.
