Django: transfering two primary keys to new detail view - django

Question

I'm trying to create a detail view where I use employee and subject name to show the evaluations created in the specific subject.
I currently have this detail where, where I'm looping through the subject names and displaying all the evaluations for the subject for the employee. The view is using employee as the primary key.
So when I press on the subject name from the loop below, I wish to go to a new view where I show the evaluations for the subject by the specific employee.
Employee template
{% for subject in subject_list %}
<h5>{{ subject.subjectname }}</h5>
{% for evaluation in subject.evaluation_set.all %}
{{ evaluation.instructor }}
{{ evaluation.ma }}
{% endfor %}
{% endfor %}
I can't figure out what the best way to do this is. I believe using the employee primary key for the new view is correct, but how do I "transfer" the subject id from the loop to the next view?
Alternatively I can use the subject id for the view but then I don't understand how to "transfer" the employee over.
Employee view with subjects
class EmployeeEvalDetailView(DetailView):
template_name = 'evalsys/evalueringer/se_alle_evalueringer.html'
model = Employee
def get_context_data(self, **kwargs):
context = super(EmployeeEvalDetailView, self).get_context_data(**kwargs)
context['fagene'] = Subject.objects.all().prefetch_related(Prefetch('evaluation_set', queryset=Evaluation.objects.filter(ma=self.object)))
return context
Employee model
class Medarbejder(models.Model):
id = models.AutoField(primary_key=True)
slug = models.SlugField(max_length=200)
ma = models.IntegerField(help_text="Indtast medarbejderens MA-nummer. (F.eks 123456)")
firstname = models.CharField(max_length=30, help_text="Indtast medarbejderens fornavn.")
lastname = models.CharField(max_length=30, help_text="Indtast medarbejderens efternavn.")
subject = models.ManyToManyField('Subject', related_name='medarbejder', through='Evaluering')
Evaluering model
class Evaluering(models.Model):
id = models.AutoField(primary_key=True)
oprettet = models.DateTimeField(auto_now_add=True)
opdateret = models.DateField(auto_now=True)
ma = models.ForeignKey('Employee', on_delete=models.CASCADE, null=True)
subjectname = models.ForeignKey('Subject', on_delete=models.CASCADE, null=True)
instructor = models.ForeignKey(User, on_delete=models.CASCADE, null=True)
Subject model
class Subject(models.Model):
id = models.AutoField(primary_key=True)
subjectname = models.CharField(max_length=255, help_text="Indtast navnet på faget.")
slug = models.SlugField(max_length=200, unique=True)
New detail view with multiple PK's
class FagEvalDetailView(DetailView):
model = Employee
template_name = 'evalsys/evalueringer/eksporter/detail_fag_eval.html'
def get_context_data(self, **kwargs):
context = super(FagEvalDetailView, self).get_context_data()
context['pk_alt'] = Subject.objects.get(id=self.kwargs.get('pk_alt', ''))
return context
