Flask redirecting multiple routes

Question

I\'m trying to implement a redirecting pattern, similar to what StackOverflow does:

@route(\'///\')
@route(\'//\')
de

You've almost got it. defaults is what you want. Here is how it works:

@route('///')
@route('//', defaults={'username': None})
def profile(id, username):
    user = User.query.get_or_404(id)

    if username is None or user.clean_username != username:
        return redirect(url_for('profile', id=id, username=user.clean_username))

    return render_template('user/profile.html', user=user)

defaults is a dict with default values for all route parameters that are not in the rule. Here, in the second route decorator there is no username parameter in the rule, so you have to set it in defaults.
