How to mix the order of items of a Django object on a page?-CodePudding

I am trying to create a game that allows users to play a quiz, which is stored as a Django object, but I want the order of the questions to be different (as in random) every time. Is there a way to accomplish this?

models.py

class Quiz(models.Model):
    user = models.ForeignKey(Profile, on_delete=models.CASCADE, default="")
    title = models.TextField(default="")
    question1 = models.TextField()
    answer1 = models.TextField()
    question2 = models.TextField()
    answer2 = models.TextField(default="")
    question3 = models.TextField()
    answer3 = models.TextField()
    ...

(The questions and answers go to 10.)

views.py

def quiz(request, quiz_id):
    quiz = get_object_or_404(Quiz.objects, pk=quiz_id)
    return render(request, "capstone/quiz.html", {
        "quiz": quiz
        })

I was thinking about generating a random number, but I think that would be too complicated with the number of questions. Is there any easier way to randomly display the questions to the user?

Try to use a embedded ORM function.

Quiz.objects.order_by('?')

The below will extract the questions from your queryset into a tuple containing the question and the question number, and then shuffle the tuples, putting them into their own context value

import random

def quiz(request, quiz_id):
    quiz = get_object_or_404(Quiz.objects, pk=quiz_id)
    #convert the queryset into a dict so we can get the questions
    quiz_values = quiz.values()
    quiz_questions = []
    for i in range(1,11):
        quiz_questions.append((i, quiz_values['question'   str(i)]))
    random.shuffle(quiz_questions)
    return render(request, "capstone/quiz.html", {
        "quiz": quiz, "quiz_questions": quiz_questions
        })

Then in your template, you can refer to something like

{% for q in quiz_questions %}
   {{q.1}} <!-- question text  -->
   <input type="text" name="id_question{{q.0}}">  <!-- question number -->
{% endfor %}

...so your form doesn't lose track of which question is being answered.
