django boto3: NoCredentialsError — Unable to locate credentials

Question

I am trying to use boto3 in my django project to upload files to Amazon S3. Credentials are defined in settings.py:

AWS_ACCESS_KEY          


        

Answer 1

This is what I use for a direct upload, i hope it provides some assistance.

import boto
from boto.exception import S3CreateError
from boto.s3.connection import S3Connection

conn = S3Connection(settings.AWS_ACCESS_KEY,
                    settings.AWS_SECRET_KEY,
                    is_secure=True)
try:
    bucket = conn.create_bucket(settings.S3_BUCKET)
except S3CreateError as e:
    bucket = conn.get_bucket(settings.S3_BUCKET)

k = boto.s3.key.Key(bucket)
k.key = filename
k.set_contents_from_filename(filepath)

Not sure about (a) but django is very flexible with file management.

Regarding (b) you can also sign the upload and do it directly from the client to reduce bandwidth usage, its quite sneaky and secure too. You need to use some JavaScript to manage the upload. If you want details I can include them here.
