Overview

The connection data store operates much like the Controller store. The biggest difference is that the data placed inside is private for individual users and accessible from any controller. Anything placed inside the connection data store will be deleted when a user disconnects.

The connection data store is accessed through the ‘#connection_store` instance method inside your controller.

If we were writing a basic chat system, we could use the connection data store to hold onto a user’s current screen name.

class UserController < WebsocketRails::BaseController

  def set_screen_name
    connection_store[:screen_name] = message[:screen_name]
  end

end

class ChatController < WebsocketRails::BaseController

  def say_hello
    screen_name = connection_store[:screen_name]
    send_message :new_message, "#{screen_name} says hello"
  end

end
