Django S3BotoStorage init 覆盖错误，"has no attribute 'rsplit'"

Question

跟踪的最后几行：

  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)

我有一个名为 prod.py 的文件，它导入 common.py，并相应地配置为 wsgi.py 和 manage.py 中的设置源。 prod.py 中的一行设置存储桶名称：

AWS_BUCKET_STATIC = 'myproject-static'

当我将所有内容都放在一个桶中时，如果没有覆盖，这不是问题。使用这个 class 什么的时候需要导入 rsplit 吗？它看起来应该内置于 Python，因此不需要导入。如果我理解正确，getattr(settings, 'AWS_BUCKET_STATIC') 会从 Django 找到的任何设置文件中获取变量，所以这也不应该成为问题。

完整跟踪：

  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib64/python3.4/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line
    utility.execute()

    self._wrapped = get_storage_class(settings.STATICFILES_STORAGE)()
  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'

Answer 1

它 looks like STATICFILES_STORAGE 需要一个表示模块路径的字符串：

STATICFILES_STORAGE='path.to.your.S3StaticStorage'
