def behavior
  @behavior ||= [DEFAULT_BEHAVIORS[:stderr]]
end

#behavior=(behavior) ⇒ Object

Sets the behavior to the specified value. Can be a single value, array, or an object that responds to call.

Available behaviors:

[+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. Deprecation warnings raised by gems are not affected by this setting because they happen before Rails boots up.

ActiveSupport::Deprecation.behavior = :stderr
ActiveSupport::Deprecation.behavior = [:stderr, :log]
ActiveSupport::Deprecation.behavior = MyCustomHandler
ActiveSupport::Deprecation.behavior = ->(message, callstack) {
# custom stuff
}
