Files#


A file is a data asset and it is just a regular file where you can store your data. ConnectionFile is a wrapper containing a few more details about a file such as hash or url. To download a file with real data you must make an additional method call.

The SDK provides functionality to interact with files.

This includes operations such as:

  • Uploading a file

  • Retrieving file(s)

  • Downloading a file

  • Deleting a file

Uploading a File#

In the UI, you can upload a new File by navigating to Overview -> Add data to work with.

In the SDK to upload a new ConnectionFile, use the Platform.upload_file() method.

You must provide a name for the new file and a file path where the file is located on your machine. Platform.upload_file() method returns a ConnectionFile object.

>>> file = platform.upload_file(
...     name='dummy.txt',
...     file=pathlib.Path('/home/me/file.txt'),
... )
ConnectionFile(file_name='dummy.txt')

Retrieving an existing File#

In the UI, you can get Files by navigating to Assets -> Data -> Data assets.

In the SDK, Files can be retrieved using Platform.files property.

This property returns a ConnectionFiles object.

>>> # Return a list of all files
>>> files = platform.files
[ConnectionFile(file_name='dummy.txt')]

Note

Currently Platform.files does not support any filter arguments.

Downloading an Existing File#

In the UI, you can download a File by navigating to Assets -> Data -> Data assets.

In the SDK file can be downloaded using Platform.download_file() method.

You must provide a file object and output path where the file will be downloaded.

This method returns an HTTP response indicating the status of the download operation.

>>> file = platform.files.get(name='dummy.txt')
ConnectionFile(file_name='dummy.txt')
>>> res = platform.download_file(file=file, output=pathlib.Path('/home/me/download/file.txt'))
<Response [200]>

Deleting a File#

In the UI, you can delete a File by navigating to Assets -> Data -> Data assets.

In the SDK pass a ConnectionFile instance to Platform.delete_file() method to delete it.

This method returns an HTTP response indicating the status of the delete operation.

>>> file = platform.files.get(file_name='data.txt')
ConnectionFile(file_name='data.txt')
>>> res = platform.delete_file(file)
<Response [204]>
