Multiple Flask routes to same function

In some cases you can reuse a Flask route function for multiple URLs. Or you want the same page/response available via multiple URLs. In that case you can add a second route to the function by stacking a second route decorator to the function.

The code below shows how you use the a function for multiple URLs. In case you're using parameters in one of your routes make sure to provide a default value of the function argument.

@app.route('/chopsticks/')
@app.route('/chopsticks/<int:chopstick_id>')
def chopsticks_view(chopstick_id=None):
    if chopstick_id:
        return "Chopstick {}".format(chopstick_id)
    return "Chopstick list"
