I don't think we want to be dumping to JSON, parsing from JSON, then dumping again. @ajdavis do you know of anything better to do here?

I think at worst we can use the JSON string returned by json_utils and create a Flask response out of that directly. Flask's jsonify doesn't do a whole lot more than that anyway).

I don't understand the purpose of the BSON-encoding step at all. If you look at the json_util documentation it shows:

>>> from bson import Binary, Code
>>> from bson.json_util import dumps
>>> dumps([{'foo': [1, 2]},
...        {'bar': {'hello': 'world'}},
...        {'code': Code("function x() { return 1; }", {})},
...        {'bin': Binary(b"\x01\x02\x03\x04")}])
'[{"foo": [1, 2]}, {"bar": {"hello": "world"}}, {"code": {"$code": "function x() { return 1; }", "$scope": {}}}, {"bin": {"$binary": "AQIDBA==", "$type": "00"}}]'

So I think that calling json_util.dumps directly on the input obj creates the string you want. The only additional work that Flask's jsonify does is apply some styling defaults and wrap it in a Response, you could do that in flask_pymongo.jsonify, too.

Yeah, that's kind of what I thought as well. Leaving this for 2.0, in any case.
