Why have you repeated all the definitions from the model in your form?
As you say, that isn't very DRY, but there's no reason to do it at
all.
It would have been helpful to have posted the full traceback. I
suspect your error is coming from this line:
client = forms.ModelChoiceField(User.objects.all())
which should be
client = forms.ModelChoiceField(queryset=User.objects.all())
However, as i note above, you don't need the line - or any of the
field declarations - at all. You do, however, need an inner Meta class
which defines the model the form belongs to (Survey).
