instance method
behavior=
Ruby on Rails edge
Since v4.0.13Signature
behavior=(behavior)Sets the behavior to the specified value. Can be a single value, array, or an object that responds to call.
Available behaviors:
:raise:stderr-
Log all deprecation warnings to
$stderr. :log-
Log all deprecation warnings to
Rails.logger. :notify-
Use
ActiveSupport::Notificationsto notifydeprecation.rails. :report-
Use
ActiveSupport::ErrorReporterto report deprecations. :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.
deprecator = ActiveSupport::Deprecation.new
deprecator.behavior = :stderr
deprecator.behavior = [:stderr, :log]
deprecator.behavior = MyCustomHandler
deprecator.behavior = ->(message, callstack, deprecation_horizon, gem_name) {
# custom stuff
}
If you are using Rails, you can set config.active_support.report_deprecations = false to disable all deprecation behaviors. This is similar to the :silence option but more performant.
