Public Instance Methods

behavior() click to toggle source

Returns the current behavior or if one isn't set, defaults to :stderr.

# File lib/active_support/deprecation/behaviors.rb, line 46
def behavior
  @behavior ||= [DEFAULT_BEHAVIORS[:stderr]]
end
behavior=(behavior) click to toggle source

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.
