Flask-Storm

Flask-Storm is an extension for Flask that adds support for Canonical's ORM Storm to your application. Flask-Storm automatically opens and closes database connections on demand when requests need them.

Example

Access to the database is done using the store application context local. Within an application context this variable holds a reference to a Storm Store instance. If no connection is opened it will automatically open one. When the application context is torn down, normally after the request has returned, the store is closed.

from flask_storm import store
from storm.locals import Int, Unicode

class User(object):
    __storm_table__ = "users"

    id = Int(primary=True)
    name = Unicode()


@app.route("/")
def index():
    # Get name of user with ID 1
    return store.get(User, 1).name

Installation

pip install flask_storm[fancy]

This installs Flask-Storm with SQL highlighting and reformatting support. If you do not want this drop the fancy.

pip install flask_storm
