I don't think he mentions this in any of the videos (it's a bit chaotic at times), but this is used in the code presented in this video. Basically: Rails gives you two flash message types built-in: notice and alert. And they let you write code like notice: "You must be logged in to access that page." . This method allows you to add your own, custom types of flash messages. You can name them here and then use in your code. This is what happens here - Jason adds :success flash message type and he may now use things like flash[:success] and success: "You registered successfully!" . Here's more:
