Shouldn't there be an explicit way to set any field to optional?
Currently it seems to decide based on whether there is a validator:
widgets/forms.py
...
332 class FormField(InputWidget):
...
350 def _get_is_required(self):
351 validator = self._retrieve_validator_from_validation_schema()
352 if validator is None:
353 return False
354 else:
355 try:
356 validator.to_python('')
357 except validators.Invalid:
358 return True
359 else:
360 return False
361 is_required = property(_get_is_required)
Could I just add something in there which checks for a "optional=True"
parameter?
