        cleaned_data = super(ReadOnlyFieldsMixin,self).clean()
        for field in self.readonly_fields:
           cleaned_data[field] = getattr(self.instance, field)

        return cleaned_data

Usage, just define which ones must be read only:

class MyFormWithReadOnlyFields(ReadOnlyFieldsMixin, MyForm):
    readonly_fields = ('field1', 'field2', 'fieldx')
