{{{
    self.instance = construct_instance(self, self.instance, opts.fields, opts.exclude)
}}}

however, the cleaned_data might not be good. It is probably good to have a single line inserted before the first line of code of this method:

{{{
def _post_clean(self):
   if self._errors: return
   ...
