How can I convert a list to return a Json?

Question

I have the following code and need to retrieve faq type questions from a bd, how can I convert the list returned to a json, the following code presents: Object of type 'Question' is not JSON serializable

I'm using flask and Python3

@app.route("/faq/<question>")

@app.route("/faq/",defaults={"question":None})

def teste(question):
   r=Question.query.all()

   return jsonify(r)

Object of type 'Question' is not JSON serializable

looks like r is not a list.Its a object. you need to convert it to a list first. — ns15, May 31 '19 at 14:15
Then it *is* a list; and the problem is the type of its elements. — Christoph Burschka, May 31 '19 at 14:28

Your list contains Question objects that aren't serializable as JSON. If you want the output to be a list of strings, you should use

jsonify(list(map(str, r)))

(This assumes that the question objects can be converted to string.)
