Django S3BotoStorage __init__ override error , “has no attribute 'rsplit'”

Question

The last lines of the trace:

  File "/usr/local/lib64/python3.4/site-packages/django/core/files/storage.py", line 328, in get_storage_class
    return import_string(import_path or settings.DEFAULT_FILE_STORAGE)
  File "/usr/local/lib64/python3.4/site-packages/django/utils/module_loading.py", line 15, in import_string
    module_path, class_name = dotted_path.rsplit('.', 1)
AttributeError: type object 'S3StaticStorage' has no attribute 'rsplit'

S3StaticStorage :

class S3StaticStorage(S3BotoStorage):
    def __init__(self, *args, **kwargs):
        kwargs['bucket'] = getattr(settings, 'AWS_BUCKET_STATIC')
        super(S3StaticStorage, self).__init__(*args, **kwargs)

I have a file called prod.py which imports common.py , and this is configured accordingly as the settings source in wsgi.py and manage.py . A line in prod.py sets the bucket name:

AWS_BUCKET_STATIC = 'myproject-static'

This was not a problem without the override, when I was putting everything in one bucket. Do I need to import rsplit when using this class or something? It looks like it should be in-built to Python so wouldn't need an import. If I understood it correctly, getattr(settings, 'AWS_BUCKET_STATIC') would get the variable from whatever settings files Django finds, so that shouldn't be a problem either.

看起来 STATICFILES_STORAGE期望一个表示模块路径的字符串：

STATICFILES_STORAGE='path.to.your.S3StaticStorage'
