Authentication / Adding Log Out

Adding Log Out

To log out of the application, we can add a button to the top of . This layout is where you put HTML that you want to include in every page like a header or footer.

Add a small <nav> section inside the <body> with a link to Home and a Log out button and wrap yield with a <main> tag.

<!DOCTYPE html>
<html>
  <!-- ... -->
  <body>
    <nav>
      <%= link_to "Home", root_path %>
      <%= button_to "Log out", session_path, method: :delete if authenticated? %>
    </nav>

    <main>
      <%= yield %>
    </main>
  </body>
</html>

This will display a Log out button only if the user is authenticated. When clicked, it will send a DELETE request to the session path which will log the user out.
