Why are my links not working for my ruby on rails site? Links stay on same page when clicked on

问题

My links aren't working for my ruby on rails site. When I click the link the site stays on the same page. I'm following code from a book called: "RailsSpace: Building a social networking site with ruby on rails" By Michael Hartl. The book is available free for download you can follow the code for yourself, its on pages 55-56 starting under the title "adding navigation". Here is a link to the ebook.

Thanks for your help.

I tried googling the "link_to" function and changing the format, all it did was generate more errors please help.

Here is the code from my app/views/layout/site.html.erb file:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
  <html>
    <head>
      <title><%= @title %></title>
      <%= stylesheet_link_tag "site" %>
    </head>
    <body>
      <div id="whole_page">
        <div id="header">RailsSpace</div>
        <div id="nav">
          <%= link_to_unless_current "Home", :action => "index" %> |
          <%= link_to "About Us" , :action => "help" %> |
          <%= link_to_unless_current "Help", :action => "help" %>
          <div style="background-color:white">
            <h1>Welcome to RailSpace!</h1>
            <p>This is going to be the best site ever!</p>
          </div>
        </div>
        <div id="content">
          <%= @content_for_layout %>
        </div>
      </div>
    </body>
  </html>

Here is the code for my app/controllers/site_controller.rb file:

class SiteController < ApplicationController

  def index
    @title = "Welcome to RailsSpace!"
  end

  def about
    @title = "About RailsSpace"
    @header = "Hello"
  end

  def help
    @title = "RailsSpace Help"
  end

end

Here is the code for my config/routes.rb file:

Rails.application.routes.draw do
  get  'site/index'
  get '/site/about'
  get 'site/help'

  root  'site#index'

// Here is the output from the console when I click on a link as requested:

 Started GET "/site/about" for ::1 at 2019-10-01 15:28:48 -0700
 Processing by SiteController#about as HTML

Thanks for all your help

When I click on the links in my navbar the site stays on the same page. Please help.

Thanks To Mr. Rockwell Rice, he suggested that I replace <%= @content_for_layout %> with <%= yield %> and it actually worked. All praise goes to Mr. Rockwell Rice. Thanks alot man.
