Toolkit for storing files and attachments in web applications

DEPOT - File Storage Made Easy

DEPOT is a framework for easily storing and serving files in web applications on Python2.6+ and Python3.2+.

Installing

Installing DEPOT can be done from PyPi itself by installing the filedepot distribution:

$ pip install filedepot

Getting Started

To start using Depot refer to Documentation

DEPOT was presented at PyConUK and PyConFR in 2014

Here is a simple example of using depot standalone to store files on MongoDB:

from depot.manager import DepotManager

# Configure a *default* depot to store files on MongoDB GridFS
DepotManager.configure('default', {
    'depot.backend': 'depot.io.gridfs.GridFSStorage',
    'depot.mongouri': 'mongodb://localhost/db'
})

depot = DepotManager.get()

# Save the file and get the fileid
fileid = depot.create(open('/tmp/file.png'))

# Get the file back
stored_file = depot.get(fileid)
print stored_file.filename
print stored_file.content_type

ChangeLog

0.5.2

• Fixed an start_response called a second time without providing exc_info error with storages supporting plublic urls

0.5.1

• URLs generated by DepotMiddleware are now guaranteed to be plain ascii
• [Breaking change]: Bucket existance with S3 storages should now be more reliable when the bucket didn't already exist, but it requires an additional AWS policy: s3:ListAllMyBuckets that wasn't required on 0.5.0

0.5.0

• depot.io.boto3.S3Storage now provides support for accessing S3 with boto3. The previously existing depot.io.awss3.S3Storage can still be used to store files on S3 using boto.
• SQLAlchemy integration now handles deletion of files on rollback when session is not flushed. Previously flushing the session was required before a rollback too.
• It is now possible to run tests through tox and build docs through tox -e docs
• DEPOT is now tested against Python 3.6

0.4.1

• Fixed installation error on non-UTF8 systems
• Improved support for polymorphic subtypes in SQLAlchemy

0.4.0

• Support for Python 3.5
• Fixed Content-Disposition header for filenames including a comma

0.3.2

• MemoryFileStorage now accepts any option, for easier testing configuration

0.3.1

• Fixed Content-Disposition header when serving from S3 directly
• Fixed size of SQLAlchemy field on Oracle (was bigger than the allowed maximum)

0.3.0

• MemoryFileStorage provides in memory storage for files. This is meant to provide a convenient way to speed up test suites and avoid fixture clean up issues.
• S3Storage can now generate public urls for private files (expire in 1 year)
• Files created from plain bytes are now named "unnamed" instead of missing a filename.

0.2.1

• S3Storage now supports the prefix option to store files in a subpath

0.2.0

• Storages now provide a list method to list files available on the store (This is not meant to be used to retrieve files uploaded by depot as it lists all the files).
• DepotExtension for Ming is now properly documented

0.1.2

• It is now possible to use multiple WithThumbnailFilter to generate multiple thumbnails with different resolutions.
• Better documentation for MongoDB UploadedFileProperty

0.1.1

• Fixed a bug with Ming support when acessing UploadedFileProperty as a class property
• Improved support for DEPOT inside TurboGears admin when using MongoDB

0.1.0

• Added DepotManager.alias to configure aliases to storage. This allows easy migration from one storage to another by switching where the alias points.
• Now UploadedFileField permits to specify upload_storage to link a Model Column to a specific storage.
• Added policy and encrypt_key options to S3Storage to upload private and encrypted files.

0.0.6

• Added host option to S3Storage to allow using providers different from AWS.

0.0.5

• Added FileIntent to explicitly provide content_type and filename to uploaded content.

0.0.4

• Added Content-Disposition header with original filename in WSGI middleware

0.0.3

• Work-Around for issue with wsgi.file_wrapper provided by Waitress WSGI Server

0.0.2

• Official Support for AWS S3 on Python3
