Question

I have a form in Django that looks like this

class FooForm(forms.ModelForm):
    foo_field = forms.ModelChoiceField(widget=FooWidget(def_arg=self.data))

Where I call self.data, Python throws the exception name 'self' is not defined. How can I access self there?

Answer 1

As others have answered, there is no self to refer to at that point. Something like this does work though:

class FooForm(forms.ModelForm):
    foo_field = forms.ModelChoiceField()

    def __init__(self, *args, **kwargs):
        super(FooForm, self).__init__(*args, **kwargs)
        self.fields['foo_field'].initial = self.data

You can also access the widget in __init__ through self.fields['foo_field'].widget
