Overview

The [before_command](ClassMethods#before_command), [after_command](ClassMethods#after_command), and [around_command](ClassMethods#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 :

    private

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