- Virtual Field Descriptions
- ==========================
- Some fields including in the various Mappers don't rely on any actual field in
- the Model (e.g., ``_action`` or ``batch``).
- In order to prevent any side-effects when trying to retrieve the value of this
- field (which doesn't exist), the option ``virtual_field`` is specified for these
- fields.
- When the template is instantiated, or whenever the value of the field is
- required, ``null`` will simply be returned without prying on the Model itself.
