A bunch of Flask decorators that I used

decorators.py

def role_required(role=ROLE_USER):
    def wrapper(f):
        @wraps(f)
        def role_checker(*args, **kwargs):
            if not current_user.is_authenticated:
                abort(403)

            if role == ROLE_USER or current_user.role == role:
                return f(*args, **kwargs)
            else:
                abort(403)

        return role_checker

    return wrapper


def unauthenticated_required(f):
    @wraps(f)
    def wrapper(*args, **kwargs):
        if not current_user.is_authenticated:
            return f(*args, **kwargs)
        return redirect(url_for('index'))

    return wrapper
