Flask-And-Redis 0.3.3

Advanced

Some times, your redis setting stored as redis://... url (like in Heroku or DotCloud services), sou you could to provide just REDIS_URL value and Flask-And-Redis auto parsed that url and configured then valid redis connection.

Basic

from flask import Flask
from flask.ext.redis import Redis


app = Flask(__name__)
redis = Redis(app)

Test application

testapp/app.py

from flask import Flask, redirect, url_for
from flask.ext.redis import Redis

from testapp import settings


# Initialize simple Flask application
app = Flask(__name__)
app.config.from_object(settings)

# Setup Redis conection
redis = Redis(app)

# Add two simple views: One for forgetting counter
@app.route('/forget-us')
def forget_us():
    key = app.config['COUNTER_KEY']
    redis.delete(key)
    return redirect(url_for('home'))


# Second for remembering visiting counter
@app.route('/')
def home():
    key = app.config['COUNTER_KEY']
    counter = redis.incr(key)
    message = 'Hello, visitor!'

    if counter != 1:
        message += "\nThis page viewed %d time(s)." % counter

    return message

testapp/settings.py

COUNTER_KEY = 'testapp:counter'
REDIS_HOST = 'localhost'
REDIS_PORT = 6379
REDIS_DB = 0
# REDIS_URL = 'redis://localhost:6379/0'
