ActiveSupport::Deprecation::Behavior

Behavior module allows to determine how to display deprecation messages. You can create a custom behavior or set any from the DEFAULT_BEHAVIORS constant. Available behaviors are:

:raise

Raise ActiveSupport::DeprecationException.

:stderr

Log all deprecation warnings to $stderr.

:log

Log all deprecation warnings to Rails.logger.

:notify

Use ActiveSupport::Notifications to notify deprecation.rails.

:report

Use ActiveSupport::ErrorReporter to report deprecations.

:silence

Do nothing. On Rails, set config.active_support.report_deprecations = false to disable all behaviors.

Setting behaviors only affects deprecations that happen after boot time. For more information you can read the documentation of the #behavior= method.
