title: In Django, how to determine if translation for a given text is available?
body: <p>I would like to determine, if there's a translation to current language for a given string. I'd like to write something like:</p>
  
  <pre><code>if not translation_available("my string"):
      log_warning_somewhere()
  </code></pre>
  
  <p>I didn't find anything appropriate. The <code>ugettext</code> function just returns the translation or the original string (if the translation isn't available) but without any option to determine if the translation is there or isn't. </p>
  
  <p>Thanks.</p>
