Field values

When you query a value you always specify whether that value is optional or required:

>>> document.field('default_settings').required_string_value()
>>> document.field('extra_settings').optional_string_value()

The optional_* query returns a value or None, while the required_* query raises a validation error if the value is missing, such as:

The field 'default_settings' must contain a value.

Fieldset entry values

This works just like on a field:

>>> document.fieldset('image').entry('src').required_string_value()
>>> document.fieldset('image').entry('title').optional_string_value()
