send model form as a json response in django

I want to send a modelform to my template using through json response(I've no idea if it's possible or not).

Actually in my template I have a list of objects from a model, and when i click them i send a post request to my view through ajax or axios with the object id, then in view I'm creating the model form of that object and I want to send that the model form of instance object back to template.

to summarize it up how can i send an model form through json response.(If not possible how to )

updated!

this is my forms.py

...
class UpdateMedicalRecordForm(forms.ModelForm):
    class Meta:
        model = MedicalRecords
        fields = ("title", "file", "doctor", "doctor_access", "general_access")

        widgets = {
            "title": forms.Textarea(attrs={"rows": "", "class": "form-control", "placeholder": "Optional"}),
            "file": forms.FileInput(attrs={"class": "form-control"}),
            "doctor": forms.Select(attrs={"class": "form-control"}),
        }
        labels = {
            "title": "Description (Optional)",
            "general_access": "General Access For Record",
            "doctor_access": "Doctor Access For Record",
        }

then in views.py i'm getting the medicalrecord, ID through the ajax and make a UpdateMedicalRecordForm() modelform for that instance as

from_instace = UpdateMedicalRecordForm(
    request.POST, request.FILES,
    instance=get_object_or_404(MedicalRecords, id=request.POST.get("file-id"))
)

here i don't know how to send my response back to template, to use it as form.as_p or loop through that.

...
JsonResponse({
   "form": ??
})

you can use django-remote-forms like this :

    from django_remote_forms.forms import RemoteForm
    from django.forms.models import model_to_dict

    ####
    form = UpdateMedicalRecordForm(
        request.POST, request.FILES,
        instance=get_object_or_404(MedicalRecords, id=request.POST.get("file-id"))
    )
form['instance']=model_to_dict(form['instance'])
    remote_form = RemoteForm(form)
    remote_form_dict = remote_form.as_dict()
    response = HttpResponse(
        json.simplejson.dumps(remote_form_dict, cls=DjangoJSONEncoder),
        mimetype="application/json"
    )

    # Process response for CSRF
    csrf_middleware.process_response(request, response)
    return response

then you can parse the response in you js
