file-keeper

Abstraction layer for reading, writing and managing file-like objects.

The package implements drivers for a number of storage types(local filesystem, redis, AWS S3, etc.) and defines a set of tools to simplify building your own drivers for storage you are using.

Read the documentation for a full user guide.

Usage

Initialize storage pointing to /tmp/example folder:

import os
from file_keeper import make_storage

storage = make_storage("sandbox", {
    "type": "file_keeper:fs",
    "path": "/tmp/example",
    # this option creates the folder if it does not exist.
    # Without it storage raises an error if folder is missing
    "create_path": True,
})
assert os.path.isdir("/tmp/example")

Upload file into the storage initialized in the previous step and play with it a bit:

from file_keeper import make_upload
upload = make_upload(b"hello world")

# save the data and verify its presence in the system
result = storage.upload("hello.txt", upload)
assert result.size == 11
assert os.path.isfile("/tmp/example/hello.txt")

# change location of the file
moved_result = storage.move("moved-hello.txt", result, storage)
assert not os.path.exists("/tmp/example/hello.txt")
assert os.path.isfile("/tmp/example/moved-hello.txt")

# read the file
assert storage.content(moved_result) == b"hello world"

# remove the file
storage.remove(moved_result)
assert not os.path.exists("/tmp/example/moved-hello.txt")
