Action Cable Connection Callbacks

The before_command, after_command, and around_command callbacks are invoked when sending commands to the client, such as when subscribing, unsubscribing, or performing an action.

Example

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
