No, there isn't - this is one of the frustrating parts of customising
a ModelForm. You can't get the default widget attributes either.
There is an alternative, though: instead of overriding the fields
declaratively, you can define a formfield_callback function. This gets
passed each model field and must return a form field, but you can do
anything you want to it in the meantime. So, for example:
def customise_formfields(field):
field_obj = field.formfield()
if field.name == 'disk_type':
existing_choices = field_obj.choices
field_obj.widget = choicewidget(choices=existing_choices)
return field_obj
class CustomModelForm(forms.ModelForm):
formfield_callback = customise_formfields
