Comment (by Bishnu Bhattarai):
class BillingForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(BillingForm, self).__init__(*args, **kwargs)
self.fields['account'].queryset = Account.objects.all()
self.fields['refrence'].queryset = Billing.objects.all()
class Meta:
model = Billing
fields = ('account', 'refrence', 'amount', 'remarks', )
views.py
class BillingUpdateView(SuccessMessageMixin, UpdateView):
template_name = 'billing/billing-form.html'
model = Billing
form_class = BillingForm
success_url = reverse_lazy('billing_report')
success_message = 'Billing Updated Successfully.'
@method_decorator(staff_required())
def dispatch(self, request, *args, **kwargs):
return super().dispatch(request, *args, **kwargs)
I have 200 rows in Account table and 4-5K rows in Billing table. Try to
render the above example form with number of rows that I have mentioned
and see the response time. You can use model_mummy for generate dummy
data.
