# API for managed folders¶

This class lets you interact with managed folders in Python recipes and notebooks. See Managed folders for more information.

class dataiku.core.managed_folder.Folder(lookup, project_key=None, ignore_flow=False)

This is a handle to interact with a managed folder.

Note: this class is also available as dataiku.Folder

get_info(sensitive_info=False)

Get information about the location and settings of this managed folder :rtype: dict

get_partition_info(partition)

Get information about the partitions of this managed folder :rtype: dict

get_path()

Gets the filesystem path of this managed folder. This method can only be called for managed folders that are stored on the local filesystem of the DSS server.

is_partitioning_directory_based()

Whether the partitioning of the folder is based on sub-directories

list_paths_in_partition(partition='')

Gets the filesystem paths of the folder for the given partition (or for the entire folder)

list_partitions()

Gets the partitions in the folder

Return type: list
get_partition_folder(partition)

Gets the filesystem path of the directory corresponding to the partition (if the partitioning is directory-based)

get_id()
get_name()
file_path(filename)

Gets the filesystem path for a given file within the folder. This method can only be called for managed folders that are stored on the local filesystem of the DSS server.

Parameters: filename (str) – Name of the file within the folder
read_json(filename)

Reads a JSON file within the folder and returns its parsed content

Parameters: filename (str) – Path of the file within the folder list or dict: Depending on the content of the file
write_json(filename, obj)

Writes a JSON-serializable (mostly dict or list) object as JSON to a file within the folder

Parameters: filename (str) – Path of the target file within the folder obj (str) – JSON-serializable object to write (generally dict or list)
clear()

Removes all files from the folder

clear_partition(partition)

clear_path(path)

Removes a file or directory from the folder

get_path_details(path='/')

Get details about a specific path (file or directory) in the folder

Return type: dict
get_download_stream(path)

Gets a file-like object that allows you to read a single file from this folder. If the file already exists, it will be replaced.

with folder.get_download_stream("myfile") as stream:
print("First line of myfile is: \%s" \% data)

Return type: file-like
upload_stream(path, f)

Uploads the content of a file-like object to a specific path in the managed folder. If the file already exists, it will be replaced.

# This copies a local file to the managed folder

Parameters: path (str) – Target path of the file to write in the managed folder f – file-like object open for reading
upload_file(path, file_path)
