Flask-UUID is a simple Flask extension that registers a UUID converter for urls on a Flask application. It uses the standard library's uuid module to convert UUIDs to and from strings.

This extension allows you to easily route and generate urls containing UUID parts, e.g. /page/fe4a3e33-cb4b-42ac-a29b-a8160a85af7e.

Installation is trivial:

$ pip install Flask-UUID

Flask-UUID is a well-behaved Flask extension, so you can either initialise it directly upon instantiation:

from flask import Flask
from flask_uuid import FlaskUUID

app = Flask(__name__)
FlaskUUID(app)

Or initialise it like this:

from flask import Flask
from flask_uuid import FlaskUUID

app = Flask(__main__)

flask_uuid = FlaskUUID()
flask_uuid.init_app(app)

Now you can use it in your routes like any other converter:

@app.route('/<uuid:id>')
def mypage(id):
    return id  # 'id' is a uuid.UUID instance

You can also use UUID instances to generate urls:

random_uuid = uuid.uuid4()
url = url_for('mypage', id=random_uuid)

Note that, by default, the converter only accepts and generates lowercase hexadecimal UUIDs with dashes at the proper places, in order to keep urls unique. If you want to accept any UUID string accepted by the uuid.UUID() constructor, simply set the strict flag to `False`:

@app.route('/<uuid(strict=False):id>'>
def mypage(id):
    return id
