Overview
Action Cable Channel Callbacks
Action Cable Channel provides hooks during the life cycle of a channel subscription. Callbacks allow triggering logic during this cycle. Available callbacks are:
-
before_subscribe -
after_subscribe(also aliased as:on_subscribe) -
before_unsubscribe -
after_unsubscribe(also aliased as:on_unsubscribe)
NOTE: the after_subscribe callback is triggered whenever the subscribed method is called, even if subscription was rejected with the reject method. To trigger after_subscribe only on successful subscriptions, use after_subscribe :my_method_name, unless: :subscription_rejected?
