python - Overriding initial value in ModelForm

in my Django (1.2) project, I want to prepopulate a field in a modelform, but my new value is ignored. This is the snippet:

class ArtefactForm(ModelForm):
    material = CharField(widget=AutoCompleteWidget('material', force_selection=False))

    def __init__(self, *args, **kwargs):
        super(ArtefactForm, self).__init__(*args, **kwargs)
        self.fields['material'].initial = 'Test'

I also tried with self.base_fields, but no effect: there is always the database-value displaying in the form. Any ideas?

Try this:

def __init__(self, *args, **kwargs):
    initial = kwargs.get('initial', {})
    initial['material'] = 'Test'
    kwargs['initial'] = initial
    super(ArtefactForm, self).__init__(*args, **kwargs)
