[SOLVED] Django forms.py initialized wrongly?

Django forms.py initialized wrongly?

I have a django view communicate the user's preferred locale to a form in forms.py. However, that form seems to get initialized before I even call it.

Class SurveyForm() seems to load before my call from views.py and even before the SurveyForms() init function becomes active.

Here is the code:

class SurveyForm(forms.Form):
    questions = Question.objects.all()
    Q1 = questions.get(identifier='Q1')
    question1 = forms.CharField(required=False, label=Q1.name)

    def __init__(self, *args, **kwargs):
        translation.activate('nl')

When I put translation.activate('nl') in the SurveyForm class, it does work. When I put translation.activate('nl') in the __init__, or in views.py, it does not work. How can this be changed?

Note: I use modeltranslation, so Q1.name will get the Dutch translation when Dutch language is active.

Solution

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 = ...
