Rails通过表单传递表单ID参数

I'm new to rails and I am building a todo list app. I am trying to set it up- like Trello so I can output multiple lists and have items under each list. So currently I can create lists, and within each list create list items. Everything is working by taking the player between the different pages but I am trying to combine it all into one page.
