##Flask-SQLAlchemySession
Provides an SQLAlchemy scoped session that creates unique sessions per Flask request, following the guidelines documented at Using Custom Created Scopes.
http://flask-sqlalchemy-session.readthedocs.org
###Usage
Initialize a flask_scoped_session as you would a
scoped_session, with the addition of a Flask
app. Then use the resulting session to query models:
from flask import Flask, abort, jsonify
from flask_sqlalchemy_session import flask_scoped_session
app = Flask(__name__)
session = flask_scoped_session(session_factory, app)
@app.route("/users/<int:user_id>")
def user(user_id):
user = session.query(User).get(user_id)
if user is None:
abort(404)
return flask.jsonify(**user.to_dict())The current_session is also provided as a convenient accessor to the session
of the current request, in the same spirit of flask.request and
flask.current_app.
from flask_sqlalchemy_session import current_session
@app.route("/users/<int:user_id>")
def user(user_id):
user = current_session.query(User).get(user_id)
if user is None:
abort(404)
return flask.jsonify(**user.to_dict())You can run the tests by invoking PYTHONPATH=. py.test tests/ in the repository root.
