Why I can't use redirect_to '/pages/:id'? It said the 'id' params doesn't passed into the #show action.

All info is above. Thank you!

redirect_to("/pages/:id") will literally redirect the browser to load the path "/pages/:id". So if you have a get "/pages/:id", to: "pages#show" route set up, then when show is called, params[:id] will be set to the string ":id", which is not what you want.

Instead, you should pass redirect_to a model object that has its id attribute set:

redirect_to @page

Or you should interpolate the ID into a string, and pass that to redirect_to:

redirect_to "/pages/#{@page.id}"

Here's what it would look like in a controller action:

  def create
    @page = Page.new(page_params)

    if @page.save
      redirect_to @page, notice: 'Page was successfully created.'
    else
      render :new
    end
  end
