title: Django - Media upload [Errno 13] Permission denied
body: <p>I'm having some trouble getting django to play nice with image uploads. My script will create directories based on the date like so:</p>
  
  <pre><code>file = models.FileField(upload_to='uploads/%m-%Y/')
  </code></pre>
  
  <p>Now, if I create the dated directory in the uploads folder and chmod the folder to 755, the upload works fine, but if I try to chmod the uploads folder without creating the dated sub folder (which I need django to do), I am getting a permissions error.</p>
  
  <p>How do I make it so a folder will allow the creation of sub folders? </p>
  
  <p>Here is a traceback:</p>
