title: Django site creating a link from html page to another app's main html page
body: <p>I have an index page in a django project that has (in it's header.html page) a navigation bar. I want the navigation bar to actually work ...currently when I click on 'teachers' in the nav bar I get an error.</p>
  
  <p>The code in header.html (which has the nav bar)</p>
  
  <pre><code>&lt;/button&gt;
          &lt;div class="collapse navbar-collapse" id="navbarResponsive"&gt;
            &lt;ul class="navbar-nav ml-auto"&gt;
              &lt;li class="nav-item mx-0 mx-lg-1"&gt;
                &lt;a class="nav-link py-3 px-0 px-lg-3 rounded js-scroll-trigger" href="/teachers/teachers.html"&gt;Teachers&lt;/a&gt;
              &lt;/li&gt;
          &lt;/div&gt;
  </code></pre>
  
  <p><strong>The link above in question is:</strong></p>
  
  <p>href="/teachers/teachers.html">Teachers</p>
  
  <p><strong>The file path/structure of where the teachers.html page is:</strong>
  C:\Users\User\Desktop\rast\teachers\templates\teachers</p>
  
  <p><strong>The error:</strong></p>
  
  <pre><code>Using the URLconf defined in website.urls, Django tried these URL patterns, in this order:
  
  admin/
  admin/
  header/ [name='header']
  [name='index']
  teachers/
  The current path, teachers.html, didn't match any of these.
  </code></pre>
  
  <p><strong>My question is</strong> - what do I need to write in the header.html page (or do I need to dos something else?) to get the nav bar button 'teachers' to go to the teachers.html page.</p>
