[Answered ]-Django forms.py initialized wrongly?

Anything at class level is executed when the class is defined, on first import. You already know how to do things at instantation time – by doing it in the __init__ method.

It’s not clear from your question what Q1 is. Is it a field? If so you can add it to self.fields; otherwise just set it directly on self.

def __init__(self, *args, **kwargs):
    translation.activate('nl')
    super(SurveyForm, self).__init__(*args, **kwargs)
    self.fields['Q1'] = ...
    # or
    self.Q1 = ...
