track a current bitly link

[rafaelmagalhaes]

How can i track the current bitly link?
I get the following error when i use clicks

Failed secondary: {'errorCode': 500, 'errorMessage': 'ALREADY_A_BITLY_LINK', 'results': None, 'statusCode': ''}

I created a field called shorurl on modes.py

on the View i added
self.object.shorturl = Bittle.objects.bitlify(self.object.upload.url).shortUrl
on the html template i did {{ document.shorturl |clicks }}
but this gives me the error ALREADY_A_BITLY_LINK
