Route Parameter for link_to "New Todo Item"

I am sort of confused when the link for New Todo Item was defined within the index.html.erb file of Todo Items. Can you explain as to why the parameter is not required here? I was expecting the path of todo_list_todo_item_path to have a parameter of @todo_list since when you run rake routes it has a :todo_list_id within the URI. Moreover, I thought that this was needed so when we create a new item how would it then determine how to associate this particular item to a particular todo list.

Hey Nikolai Montesclaros good catch! That appears to have been cut from the video. We'll get that added.
