I am very new to Flask (& Flask-Restful).
My problem : json arguments for a POST is getting set to NONE (not working).
According to the documentation for Request.json and the new Request.get_json, you should have the mimetype on your POST request set to application/json. This is the only way flask will automatically parse your JSON data into the Request.json property which (I believe) is what Flask-Restful depends on to retrieve JSON data.
NOTE: The newer get_json function has an option to force the parsing of POST data as JSON irrespective of the mimetype
