Django Signals and form is_valid - django

Question

This question is related to this. I would like to save my form data in relation to the created signal:
Model :
class PatientInfo(models.Model):
lastname = models.CharField('Last Name', max_length=200)
...
class MedicalHistory(models.Model):
patient = models.OneToOneField(PatientInfo, on_delete=models.CASCADE, primary_key=True)
physician_name = models.CharField('Physician', max_length=200, null=True, blank=True)
...
#receiver(post_save, sender=PatientInfo)
def create_medical_history(sender, **kwargs):
if kwargs.get('created', False):
MedicalHistory.objects.create(patient=kwargs.get('instance'))
View
class MedicalCreateView(CreateView):
template_name = 'patient/medical_create.html'
model = MedicalHistory
form_class = MedicalForm
success_url = '/'
def post(self, request, pk):
form = self.form_class(request.POST)
if form.is_valid():
patiente = form.save(commit=False)
physician_name = form.cleaned_data['physician_name'] # do not delete
patiente.save()
messages.success(request, "%s is added to patient list" % physician_name )
return redirect('index')
else:
print(form.errors)
My code above saves two entry in my MedicalHistory table, patient field is linked to Patient_info.id while the other is empty yet populated with form data.
Any help is greatly appreciated.

Answer 1

Since my MedicalHistory model is has generated its its own automatically, based in my PatientInfo . My way of populating data to existing MedicalHistoryid is by changing:
class MedicalCreateView(CreateView)
to
class MedicalCreateView(UpdateView):
I removed this
def post(self, request, pk):
form = self.form_class(request.POST)
if form.is_valid():
patiente = form.save(commit=False)
physician_name = form.cleaned_data['physician_name'] # do not delete
patiente.save()
messages.success(request, "%s is added to patient list" % physician_name )
return redirect('index')
else:
print(form.errors)
