Overview

Action Cable Connection Callbacks

There are before_command, after_command, and around_command callbacks available to be invoked before, after or around every command received by a client respectively. The term “command” here refers to any interaction received by a client (subscribing, unsubscribing or performing actions):

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :user

    around_command :set_current_account

    private

    def set_current_account
      # Now all channels could use Current.account
      Current.set(account: user.account) { yield }
    end
  end
end
