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.

silence

Do nothing.

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