A clean abstraction over cloud file storage platforms like S3, Alicloud, or Heroku.

Project description

Simple cloud file storage for Flask applications on platforms like S3, Alicloud, or Heroku.

import os

from flask import Flask
from flask_warehouse import Warehouse

# 1. Configuring Warehouse
app = Flask(__name__)
app.config['WAREHOUSE_DEFAULT_SERVICE'] = 's3'          # or 'file' for filesystem
app.config['WAREHOUSE_DEFAULT_LOCATION'] = 'us-west-1'  # required for 's3'
app.config['WAREHOUSE_DEFAULT_BUCKET'] = None


app.config['AWS_ACCESS_KEY_ID'] = '...'                 # required for 's3'
app.config['AWS_SECRET_ACCESS_KEY'] = '...'             # required for 's3'

warehouse = Warehouse(app)

# Object-oriented approach:
bucket = warehouse.bucket('mybucket')
oo_cubby = bucket.cubby('keys')

# Or compact approach:
compact_cubby = warehouse('s3:///mybucket/keys')

assert oo_cubby == compact_cubby

cubby = oo_cubby

# 2. Writing to/from bytes
contents = b'12345'
cubby.store(bytes=contents)

assert cubby.filesize() == 5

cubby_contents = cubby.retrieve()
assert cubby_contents == contents

# 3. Writing to/from files
filepath = "local.txt"
with open(filepath, 'wb') as f:
    f.write(b"Here are the contents of a file.")

cubby.store(filepath=filepath)
assert os.path.getsize(filepath) == cubby.filesize()

assert cubby.retrieve() == open(filepath, 'rb').read()
```
