flask nested post data

I'm trying to build in a way to handle a large number of posted options, e.g. ``` my_posted_data = {"item": "value", "item_options":{"a":2, "b":2} } ``` This would be coming from somewhere else in an api situation where I'm not in control of the environment and it is simulated for now. I'll post that through the requests library; and moving server-side, I try to get this from the route/view in my application. request.form gets read into a variable(form) which is passed to a `task_manager` queue. In the task I'll try to do: ``` options = form.get("item_options", None) ``` `options` always ends up as `NoneType`. Why is this not selecting the dict(like) value of `{"a": 2, "b": 2}`? I guess I'm doing it wrong, but what at this point I am unable to pinpoint. Based on this scant picture I've provided, how do I post and and retrieve nested values with Flask request in the most effective way? EDIT: I had to go a different way, using JSON data because I realized for the situation that is best, the form is more for user input from an html page, and this is something that requires a different approach.
