Regrouping in Django Template With Grouping in views - django

Question

I have a model with different forginekey wish I could like to group it by student. I was successfully done that but in my template, I want to nested the result or regroup it by subject according to students.
model.py
class Result(models.Model):
examtype = models.ForeignKey(ExamType, on_delete=models.CASCADE)
student = models.ForeignKey(Student, on_delete=models.CASCADE)
subject = models.ForeignKey(SubjectAppointment, on_delete=models.CASCADE)
test = models.FloatField()
exam = models.FloatField()
total = models.FloatField(blank=True, null=True)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
def save(self, *args, **kwargs):
self.total = self.test + self.exam
super().save(*args, **kwargs)
def __str__(self):
return self.student.matricnumber
def get_result_total(self):
return int(float(f'{self.test + self.exam}'))
views.py
def ReportView(request):
template_name = 'teacher/report.html'
score = Result.objects.values('student', 'exam', 'test', 'subject__subject__name').annotate(student_totalscore=Sum('total')).annotate(attending=Count('subject'))
print(score)
context = {
'score': score,
}
return render(request, template_name, context)
report.html
{% for s in score %}
{% regroup score by s.student as student_list %}
{% for a in student_list %}
<!-- {% for b in a.list %} -->
<tr>
<td>{{ b.subject__subject__name }}</td>
<td>{{ b.test }}</td>
<td>{{ b.exam }}</td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<!-- {% endfor %} -->
{% endfor %}
{% endfor %}
