- What's this?
behavior=(behavior)
public
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::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, deprecation_horizon, gem_name) { # custom stuff }
