Overview

Abstract Controller provides hooks during the life cycle of a controller action. Callbacks allow you to trigger logic during this cycle. Available callbacks are:

  • after_action

  • append_after_action

  • append_around_action

  • append_before_action

  • around_action

  • before_action

  • prepend_after_action

  • prepend_around_action

  • prepend_before_action

  • skip_after_action

  • skip_around_action

  • skip_before_action
