NotImplementedError: get_object_cdn_url() not implemented for this driver

[audreyfeldroy]

Apparently, libcloud's S3StorageDriver class does not implement the get_object_cdn_url() method. I could not find it in https://github.com/apache/libcloud/blob/95b6a68adb5cbbe071d9da509484146cff6c5626/libcloud/storage/drivers/s3.py

You can see an example of the get_object_cdn_url() method in libcloud's CloudFilesStorageDriver (for Rackspace Cloudfiles) class at https://github.com/apache/libcloud/blob/d69adbd886965c7b176b9713cdad2f954d041c3c/libcloud/storage/drivers/cloudfiles.py#L298

The error:

Template error:
In template /vagrant/created/templates/base.html, error at line 26
   get_object_cdn_url not implemented for this driver

   26 :     <link href=" {% static 'css/project.css' %} " rel="stylesheet">

The traceback:

Exception Type: NotImplementedError at /
Exception Value: get_object_cdn_url not implemented for this driver

Is there a way we could work around this by constructing the URL some other way in dj-libcloud?

Pull request https://github.com/apache/libcloud/pull/80 implemented get_object_cdn_url(), but it was closed in favor of a different change.

Sorry, I'm a little confused. How are we supposed to use S3 (or google cloud storage in my case) now?

This should be fixed per https://github.com/pydanny/dj-libcloud/commit/8663cb9567ab4e9c87ffc4a57991490ccae7cfb9
