Flask-SSS
Server-Side Sessions for Flask implemented as a SessionInterface.
##Â Data model
The user_id field allows for users to either list their open sessions and close other sessions they have open. It also enables administrators to log out all sessions for a user that needs to be suspended or deleted.
##Â Usage
from flask import Flask
from flask_sss import SQLAlchemySessionInterface
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy import Column, String, DateTime, Text
from datetime import datetime
import uuid
app = Flask(__name__)
db = SQLAlchemy(app)
class UserSession(db.Model):
__tablename__ = "user_session"
id = Column(String(length=255), primary_key=True)
session_id = Column(String(length=255), unique=True)
user_id = Column(String(length=255), nullable=True)
created_at = Column(DateTime(), nullable=False, default=datetime.utcnow)
updated_at = Column(DateTime(), nullable=False, default=datetime.utcnow, onupdate=datetime.utcnow)
expires_at = Column(DateTime(), nullable=False)
data = Column(Text(), nullable=False)
def make_id():
return str(uuid.uuid4())
app.session_interface = SQLAlchemySessionInterface(
orm_session=db.session,
sql_session_model=UserSession,
make_id=make_id
)Notes
A daily process to remove expired sessions is recommended to stop the session list expanding over time.
