Behavior module allows to determine how to
display deprecation messages. You can create a custom behavior or set any
from the DEFAULT_BEHAVIORS
constant. Available behaviors are:
raise
-
Raise
ActiveSupport::DeprecationException
. stderr
-
Log all deprecation warnings to +$stderr+.
log
-
Log all deprecation warnings to
Rails.logger
. notify
-
Use
ActiveSupport::Notifications
to notifydeprecation.rails
. silence
-
Do nothing.
Setting behaviors only affects deprecations that happen after boot time.
For more information you can read the documentation of the
behavior=
method.
[RW] | debug | Whether to print a backtrace along with the warning. |

:stderr
.

an object that responds to call

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
