Django-boto

Is an implementation of Django integration with Amazon AWS services through boto module.

Installation

To install:

easy_install django-boto

or:

pip install django-boto

Configuration

DEFAULT_FILE_STORAGE

Can't be used as default file storage system because of path not implemented but you still can pass S3Storage object as storage option to a FileField:

from django.db import models
from django_boto.s3.storage import S3Storage

s3 = S3Storage()

class Car(models.Model):
    ...
    photo = models.ImageField(storage=s3)

Other settings.py options

AWS_ACCESS_KEY_ID (required for default file storage use) Access Key ID from Security Credentials settings on AWS service. Required for using as default storage.

AWS_SECRET_ACCESS_KEY (required for default file storage use) Secret Access Key from Security Credentials settings on AWS service. Required for using as default storage.

AWS_ACL_POLICY Default canned ACL for objects saved. Defaults to public-read.

BOTO_S3_BUCKET Amazon S3 bucket name. Default set to AWS_ACCESS_KEY_ID.

BOTO_S3_HOST Amazon S3 hostname. Default to s3.amazonaws.com.

BOTO_BUCKET_LOCATION Amazon datacenter location. Default to US Classic Region.

AWS_S3_FORCE_HTTP_URL Default to False. This settings allow you forcing S3 to return http links to files (if you have problem with SSL).

Usage

Manual S3Storage usage

If you need to use it manually - you can pass bucket_name (as BOTO_S3_BUCKET), key (as AWS_ACCESS_KEY_ID), secret (as AWS_SECRET_ACCESS_KEY) and location (as BOTO_BUCKET_LOCATION) directly to storage constructor:

from django_boto.s3.storage import S3Storage

s3 = S3Storage(bucket_name='another-bucket', key='another-key',
    secret='another-secret', location='EU')

S3Storage is a typical Django storage system, only path is not implemented and created_time and accessed_time return same value as modified_time.

Upload shortcut

You can use a shortcut for simple uploads:

from django_boto.s3 import upload

upload(filename, name=None, prefix=False, bucket_name=False, key=None,
       secret=None, host=None, expires=0, query_auth=False, force_http=True,
       policy=None)

where:

filename: string filesystem path to file or django File instance or python file object instance;

name: string target Django's name for uploading the file;

prefix: string path prefix to filename in s3.amazonaws.com url. Like filename /images/image.jpg with avatars prefix convert to avatars/image.jpg in amazon url;

bucket_name: name of bucket (if not exists - system try to create it) in amazon S3;

key: AWS_ACCESS_KEY_ID replacement;

secret: AWS_SECRET_ACCESS_KEY replacement.

host: BOTO_S3_HOST replacement.

expires: int How long should private links be valid for.

query_auth: bool Should the url be generated with a valid signature? Required for private files.

force_http: bool Should the generated url be http?

policy: string Canned acl string for uploaded objects.

Last nine options are optional. If not set - it's taken from the settings.py or defaults are used.

upload() returns a generated URL for a file download.
