how to save user's inputs without backeneds - django

Question

I am just learning Django and web development in general and I was wondering if what I want to do is possible. I would like to write a Django quiz that saves the answers a user inputs without needing a backend. Is this possible?If it is not possible what is the simplest and easiest way I can do this. My template:
{% extends "base.html" %}
{% block title %}Exam Questions{% endblock %}
{% block content %}
{% if all_questions %}
<form action="{% url 'save_answer' %}" method="post">
{% csrf_token %}
{% for question in all_questions %}
<h3>{{question.text }}</h3>
<input type="hidden" name="exam_id" value="{{ question.exam.id }}">
<input type="hidden" name="question_id" value="{{ question.id }}">
<input type="hidden" value="{{question.answer_set.all}}" name="answers">
{% for answer in question.answer_set.all %}
<p><input type="radio" name="answer" value="{{ answer.id }}">{{ answer.text }}</p>
{% endfor %}
{% endfor %}
<input type="submit" value="Send">
</form>
{% else %}
<h2>No questions available</h2>
{% endif %}
{% endblock %}
Now I would like to know how to save user answers without backends

Answer 1

Afaik, you can save it in your backend (django forms doc), or save it with javascript in a client browser cookie.

Answer 2

First, make a litle change with your template to make radio choices work
<p><input type="radio" name="answer_{{ question.id }}" value="{{ answer.id }}">{{ answer.option }}</p>
Then, here is the code to store answers to session:
def post(self, request, *args, **kwargs):
post = request.POST
question_ids = post.getlist('question_id')
results = dict()
for id in question_ids:
answer = post.get('answer_%s' % id)
results[id] = answer
# Save to session or do whatever you want.
request.session['results'] = results
# Response to review
return JsonResponse(results)
