Django 2 tables in model cycle "for" in template - django

Question

I try to make a simple illustration of my question click to view
I have a task to make a quiz.
I try to solve a problem :
Taking items in cycle by "Metrix" model there I get Questions for Quiz
It is no way to get data from "User_metrix" model while using {% for item in metrix_list %} cycle by "Metrix" model.
My models:
from django.db import models
from django.conf import settings
class Metrix(models.Model):
title = models.CharField(max_length=256, verbose_name='Question')
metrix_category = models.ForeignKey(
'category',
related_name='Question_category',
on_delete=models.CASCADE,
verbose_name='Category',
)
is_published = models.BooleanField(default=False)
def __str__(self):
return self.title
class Category(models.Model):
title = models.CharField(max_length=256,
verbose_name='Question_category')
is_published = models.BooleanField(default=False)
def __str__(self):
return self.title
class User_metrix(models.Model):
user = models.ForeignKey(
settings.AUTH_USER_MODEL,
on_delete=models.CASCADE,
related_name="user_metrix",
verbose_name='User')
metrix = models.ForeignKey('Metrix', on_delete=models.CASCADE,
verbose_name='Question')
value = models.DecimalField(max_digits=12, decimal_places=2,
verbose_name='Value')
My view:
from django.shortcuts import render
from django.contrib.auth.decorators import login_required
from metrix.models import Metrix, User_metrix
#login_required
def metrix_view(request, pk=None):
metrix_category = {
'pk': 4
}
#Get questions by category
metrix_list = Metrix.objects.filter(is_published=True,
metrix_category__pk=pk)
context = {
'metrix_list': metrix_list
}
return render(request, 'metrix/metrix.html', context)
Template:
I list the questions in template, by cycle "metrix_list"
How to save answers to values and if answers exists return values to template?
<!--cycle for metrix-->
{% for item in metrix_list %}
<div class="row metrix_quiestion_line justify-content-center">
<div class="metrix_quiestion">
<h2>
{{ item }}
</h2>
</div>
<div class="metrix_value">
<input type="number" name="{{ item.id }}" value=" ">
</div>
</div>
{% endfor %}
<!--END cycle -->
