[FIXED] How do I `jsonify` a list in Flask?

Issue

Currently Flask would raise an error when jsonifying a list.

I know there could be security reasons https://github.com/mitsuhiko/flask/issues/170, but I still would like to have a way to return a JSON list like the following:

[
    {'a': 1, 'b': 2},
    {'a': 5, 'b': 10}
]

instead of

{ 'results': [
    {'a': 1, 'b': 2},
    {'a': 5, 'b': 10}
]}

on responding to a application/json request. How can I return a JSON list in Flask using Jsonify?

Solution

jsonify prevents you from doing this in Flask 0.10 and lower for security reasons.

To do it anyway, just use json.dumps in the Python standard library.
