Flask extension that ties boto3 connectors to the application context.

• Via the cheeseshop

  $ pip install flask-boto3

• Locally

  $ git clone [email protected]:Ketouem/flask-boto3.git
  $ cd flask-boto3
  flask-boto3 $ pip install .

The main class flask_boto3.Boto3 takes a Flask application as its contructor's parameter:

from flask import Flask
from flask_boto3 import Boto3
app = Flask(__name__)
app.config['BOTO3_SERVICES'] = ['s3']
boto_flask = Boto3(app)

Then boto3's clients and resources will be available as properties within the application context:

>>> with app.app_context():
        print(boto_flask.clients)
        print(boto_flask.resources)
{'s3': <botocore.client.S3 object at 0x..>}
{'s3': s3.ServiceResource()}

flask-boto3 uses several keys from a Flask configuration objects to customize its behaviour:

• BOTO3_ACCESS_KEY & BOTO3_SECRET_KEY : holds the AWS credentials, if None the extension will rely on boto3's default credentials lookup.
• BOTO3_REGION : holds the region that will be used for all connectors.
• BOTO3_PROFILE : holds the AWS profile.
• BOTO3_SERVICES : holds, as a list, the name of the AWS resources you want to use (e.g. ['sqs', 's3']).
• BOTO3_OPTIONAL_PARAMS : useful when you need to pass additional parameters to the connectors (e.g. for testing purposes), the format is a dict where the top-level keys are the name of the services you're using and for each the value is a dict containing to keys args (contains the parameters as tuple) and kwargs (contains the parameters as a dict when they should be passed as keyword arguments).
