Oops, I forgot to base Form2 on Form1. So you mean like this:
>>> from django import newforms as forms
>>> class Form1(forms.Form):
... f1 = forms.CharField()
... f2 = forms.CharField()
... f3 = forms.CharField()
...
>>> class Form2(Form1):
... f1 = forms.CharField(required=False)
...
>>> f1inst = Form1({'f2': 'x', 'f3': 'y'})
>>> f2inst = Form2({'f2': 'x', 'f3': 'y'})
>>> f1inst.is_valid()
False
>>> f2inst.is_valid()
True
>>> f2inst.fields
{'f1': <django.newforms.fields.CharField object at 0x850672c>, 'f2':
<django.newforms.fields.CharField object at 0x850678c>, 'f3':
<django.newforms.fields.CharField object at 0x85067cc>}
>>>
which seems to do what you want? Or am I missing something again?
