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.
