The issue is that CLIENT_CHOICES is only evaluated once, when the
server is started an all the code is loaded into memory. Try wrapping
it all in a function, thusly:
def CLIENT_CHOICES()
choices = [
('', 'Select Client'),
]
clients = CustomerMaster.objects.all().order_by('customer_name')
for client in clients:
choices.extend([(client.id, client.customer_name)])
return choices
class CreateForm(forms.Form):
client = forms.ChoiceField(choices=CLIENT_CHOICES())
Now, every time the model is loaded, CLIENT_CHOICES() will be called
and you'll get fresh values.
HTH.
