#cache_update_trigger(set_of_changed_card, args = {}) { ... } ⇒ Object

If a card of the set given by 'set_of_changed_card' is updated the given block is executed. It is supposed to return an array of cards whose solid caches are expired because of the update.

Parameters:

  • set_of_changed_card (set constant) —

    a set of cards that triggers a cache update

  • args (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (args):

  • :on (Symbol, Array of symbols) —

    the action(s) (:create, :update, or :delete) on which the cache update should be triggered. Default is all actions.

  • :in_stage (Stage) —

    the stage when the update is executed. Default is :integrate

Yields:

  • return an array of cards with solid cache that need to be updated
