title: How to add alert popup boxes in django?
body: <p>I've been going through the django documentation, but so far everything I've tried hasn't worked for me.  I'm trying to make it so if the user enters the url to a certain page and they are not already logged in then they are redirected to the login page that gives them a popup error message that says they don't have access to the page until they have logged in.</p>
  
  <p>Here is a small snippet of code from the views.py</p>
  
  <pre><code>def home(request):
      if request.session.test_cookie_worked():
          return render(request, 'page/home.html')
      else:
          return render(request, 'page/login.html')
  </code></pre>
  
  <p>Everything works except for the error message not popping up if they are redirected to the login page.  I've looked at other stack overflow questions that people have asked that are similar to this, but those don't seem to work for me either.  Any advice?</p>
