Using delete_memoized with route decorators

[danielstocks]

I was looking through the project test cases and I couldn't find anything covering the combination of using flask views in conjunction delete_memoized. Maybe I'm doing something really stupid here, but I'd like to know why this doesn't work:

@views.route('/users/<id>')
@cache.memoize(3600)
def get_user(id):
    user = User.query.get_or_404(id)
    return jsonify(user.to_json())

def clear_cache(id):
    cache.delete_memoized(get_user, str(id))

clear_cache(1)

This will not delete the memoized function cache. But this will:

@cache.memoize(3600)
def get_user_proxy(id):
    user = User.query.get_or_404(id)
    return jsonify(user.to_json())

@views.route('/users/<id>')
def get_user(id):
    return get_user_proxy(str(id))

def clear_cache(id):
    cache.delete_memoized(get_user_proxy, str(id))

clear_cache(1)

Would be nice to get rid of the boilerplate code above :)

Thanks in advance.
