title: Reverse for '*' with arguments '()' and keyword arguments '{}' not found
body: <p>Caught an exception while rendering:  </p>
  
  <blockquote>
    <p>Reverse for 'products.views.'filter_by_led' with arguments '()' and
    keyword arguments '{}' not found.</p>
  </blockquote>
  
  <p>I was able to successfully import <code>products.views.filter_by_led</code> from the shell and it worked so the path should be correct.</p>
  
  <p>Here is the urls.py:  </p>
  
  <pre><code>(r'^led-tv/$', filter_by_led ),
  </code></pre>
  
  <p>This is where the error is being generated:  </p>
  
  <pre><code>href="{% url products.views.filter_by_led %}"&gt;
  </code></pre>
  
  <p>Which I can't understand because this works fine from the same file:  </p>
  
  <pre><code>{% url products.views.lcd_screen_size screen_size=50 %}
  </code></pre>
  
  <p>Here is the function definition:  </p>
  
  <pre><code>def filter_by_led(request):
  </code></pre>
  
  <p>I don't understand why Django would think that the function would not be able to find the Reverse for that function.</p>
  
  <p>I deleted all the <code>*.pyc</code> files and restarted Apache.</p>
  
  <p>What am I doing wrong?</p>
