I stumbled upon a problem with Object schema field validation. The problem occurs, e.g., if the the Object field's schema itself contains a Choice field with a dynamically computed vocabulary. For the latter to validate correctly the field must be bound to the instance. But the Object field validation code in zope.schema._fields._validate_fields validates the attributes of the Object field instance without binding them first:
def _validate_fields(schema, value, errors=None): ... try: attribute = schema[name] if IField.providedBy(attribute): # validate attributes that are fields attribute.validate(getattr(value, name)) except ValidationError, error: ...
Replacing the line
attribute.validate(getattr(value, name))
with
field = attribute.bind(value) field.validate(getattr(value, name))
fixes the problem.
Looks like a bug to me.
Yeah, sounds like it. Would you mind reporting this to the bug tracker and put the bug number into this thread so people can later find it in the archive?
