JSON parsing under django framework

Question

I'm currently learning both django and javascript

I passed a json string from python to javascript and this is the string i got.

[{"model": "polls.question", "pk": 1, "fields": {"question_text": "anything", "pub_date": "2017-09-07T09:36:07Z"}}, {"model": "polls.question", "pk": 2, "fields": {"question_text": "hi", "pub_date": "2017-09-07T10:01:39Z"}}]

whenever I use the JSON.parse method my javascript crashes

javascript:

let mylist = "{{ question_list_as_json | escapejs }}";
let temp = JSON.parse(mylist);

python:

question_list = Question.objects.all()
question_list_as_json = serializers.serialize('json', question_list)
return render(request, 'polls/index.html', {'question_list': question_list, 'question_list_as_json': question_list_as_json})

in your context question_list but in the template question_list_as_json, try it:

    question_list = Question.objects.all()
    question_list_as_json = serializers.serialize('json', question_list)
    context = {
        'question_list': question_list,
        'question_list_as_json': question_list_as_json
    }
    return render(request, 'polls/index.html', context)
