[RUBY] How to display the result of form input

I will write an article for the first time I'm a beginner for a month since I started learning programming

I am creating a furima app with ruby on rails When you register as a user, list an item, and another user purchases it, the transaction is completed.

In the specifications at this stage, when the user finishes inputting the exhibited product, it will move to the top page.

def create
  @item = Item.new(item_params)
  if @item.valid?
     return redirect_to root_path #Return to top page
    render :new

Here, I am considering how to add a page that says "Product listing is complete" and click back to the top page.

--Try by writing the path in the controller

First, create an HTML document for displaying the results (let's call it kanryou) Described in the routes file

resources :items  do
  resources :orders, only: [:index, :create]
  member do
    get 'kanryou'

Described in the controller

def create
  @item = Item.new(item_params)
  if @item.valid?
     return redirect_to kanryou_item_path(@item.id)
     render :new

That worked
