title: How to add an admin page item into navigation bar (for superuser)?
body: <p>Could anybody please tell me how to realize a navigation bar containing among others an item leading to admin page?
  It should like this</p>
  
  <pre><code>                                                 Home | Faculty | Student | Admin 
  </code></pre>
  
  <p>In the following code, it works for all items in the bar, except the 'admin' one:</p>
  
  <pre><code>&lt;ul class="nav navbar-nav navbar-right"&gt;
      &lt;li&gt;&lt;a href="{% url 'home' %}"&gt;Home&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href="{% url 'faculty' %}"&gt;Faculty&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href="{% url 'student' %}"&gt;Student&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href="{% url 'admin' %}"&gt;Admin&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>In the urls file admin is described as follows:</p>
  
  <pre><code>urlpatterns = [
  url(r'^admin/', admin.site.urls, name='admin'), ...]
  </code></pre>
  
  <p>I would also appreciate if anyone enlighten me on how to make the 'admin' item visible only for superuser. Thank you very much!</p>
