title: How to rename a foreignkey field with South?
body: <p>Renaming a simple charfield etc seems easy (<a href="https://stackoverflow.com/questions/3235995/django-how-to-rename-a-model-field-using-south">Django - How to rename a model field using South?</a>) </p>
  
  <p>However when I try using the same on a ForeignKey field I get an error:</p>
  
  <pre><code>_mysql_exceptions.OperationalError: (1091, "Can't DROP '[new_fkey_field_name]'; check that column/key exists")
  </code></pre>
  
  <p>Which stems from the migration trying to run the <em>backwards</em> for some reason (as evidenced in the trace).</p>
  
  <p>Any ideas?</p>
