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 : 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.
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.
