def enable_container_cdn(self, container): (source)
Undocumented
def create_container(self, container_name): (source)
Create a new container.
Parameterscontainer_nameContainer name. (type: str)
ReturnsContainer instance on success.
def delete_container(self, container): (source)
Delete a container.
ParameterscontainerContainer instance (type: Container)
ReturnsTrue on success, False otherwise. (type: bool)
def download_object(self, obj, destination_path, overwrite_existing=False, delete_on_failure=True): (source)
Download an object to the specified destination path.
ParametersobjObject instance. (type: Object)
destination_pathFull path to a file or a directory where the incoming file will be saved. (type: str)
overwrite_existingTrue to overwrite an existing file, defaults to False. (type: bool)
delete_on_failureTrue to delete a partially downloaded file if the download was not successful (hash mismatch / file size). (type: bool)
ReturnsTrue if an object has been successfully downloaded, False otherwise. (type: bool)
def download_object_as_stream(self, obj, chunk_size=None): (source)
Return a generator which yields object data.
ParametersobjObject instance (type: Object)
chunk_sizeOptional chunk size (in bytes). (type: int)
def upload_object(self, file_path, container, object_name, extra=None, verify_hash=True): (source)
Upload an object.

Note: This will override file with a same name if it already exists.

def upload_object_via_stream(self, iterator, container, object_name, extra=None): (source)
Upload an object using an iterator.

If a provider supports it, chunked transfer encoding is used and you don't need to know in advance the amount of data to be uploaded.

Otherwise if a provider doesn't support it, iterator will be exhausted so a total size for data to be uploaded can be determined.

Note: Exhausting the iterator means that the whole data must be buffered in memory which might result in memory exhausting when uploading a very large object.

If a file is located on a disk you are advised to use upload_object function which uses fs.stat function to determine the file size and it doesn't need to buffer whole object in the memory.

ParametersiteratorAn object which implements the iterator interface. (type: object)
containerDestination container. (type: Container)
object_nameObject name. (type: str)
extra(optional) Extra attributes (driver specific).

Note: This dictionary must contain a 'content_type' key which represents a content type of the stored object.

(type: dict)
def delete_object(self, obj): (source)
Delete an object.
ParametersobjObject instance. (type: Object)
Returnsbool True on success.
