The association_proxy to the attributes breaks, at least with Flask-Restless 1.0.0b2. Not sure whether this is related to the update or the definition of the proxy is broken.

There is a pull request in jfinkels/flask-restless#608 that might be worth testing.

@Creeparoo, if we cannot get this fixed, shall we go with a self.attribute("foo", "bar") API for now until we can fix it?
