I think that's because the @jsonify decorator expects the decorated
function to have a `self` arg, so `def _jsonout(self, d): ...` should
work. You might want to refactor `_jsonout` into a method in your base
controller, then `return self._jsonout(obj_to_jsonify)`.
Also, you're converting `d` to a `dict` even though it's already a
`dict`, which isn't the problem here, but which is unnecessary.

You'd need to do `return _jsonout(self, {'spamids':[1,2,3], ...)`, but
I'd still recommend making `_jsonout` a reusable method (which also
avoids creating a new decorated function on every request).
