instance method `behavior=`

Ruby on Rails 5.2.8.1

Since v4.0.13

Available in: v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

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.
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
}

Parameters
