title: Django URL Config - Match filename
body: <p>Using Django 1.5.1 I'm trying to match:</p>
  
  <pre><code>/uploads/view/FILE_NAME.ext  eg: /uploads/view/testfile.png
  </code></pre>
  
  <p>Currently:</p>
  
  <pre><code>uploads_url_patterns = patterns('',
      url(r'^uploads/view/(?P&lt;file_name&gt;\w{0,256})/$', ShowImageView.as_view(), name='show'),
  )
  </code></pre>
  
  <p>However it doesn't match <code>/uploads/view/testfile.png</code>.</p>
  
  <p>As i'm still struggling to understand python regex's how can i match so i end up with a string including the filename and its extension or even better, its filename and extension separately?</p>
