Securing the Login for a Rails Ecommerce Application


In the first part of this four-part series we started to learn about security for an ecommerce application in Ruby-on-Rails. In this second part we're going to test some of what we did in the first part, and implement some important login features. This article is excerpted from chapter eight of the book Practical Rails Projects, written by Eldon Alameda (Apress; ISBN: 1590597818).

Securing the Login for a Rails Ecommerce Application - Adding Login Links and Styling
(Page 4 of 4 )

Letís finish off by adding links for logging in and out in the default layout file,app/views/ layouts/application.rhtml:

<div id="header">
  <h1 id="logo">Emporium&trade;</h1>
  <h2 id="slogan">Books on Rails</h2>
 
<p id="loginlogout">
    <% if current_user %>
      Logged in as <%= current_user.login %>
      (<%= link_to "Logout", :controller => "/account", :action => "logout" %>)
    <% else %>
      <%= link_to "Login", :controller => "/account", :action => "login" %>
    <% end %>
  </p>
</div>

Finally, letís add a bit of styling for the#loginlogoutbox. Openpublic/stylesheets/style.cssand add the following rules at the bottom of the file:

#loginlogout {
  background-color: #ccc;
  padding: 8px;
  width: 100px;
  position: absolute;
  top: 0px;
  right: 10px;
}

Now the login status box appears in the top-right corner of the page, as shown in Figure 8-3.
