Overview
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
