I've never used inlineformset_factory(), but I guess you can use the
formfield_callback parameter.
For example:
def my_formfield_cb(field):
if condition_on_field(field):
return SuitableFormField(widget = MyCustomWidget())
return field.formfield()
FileFormSet = inlineformset_factory(Version, File, extra=1,
formfield_callback=my_formfield_cb)
Cheers,
