Types
=====

The default mapping of an entity can be overriden.
Below is an example with CWUser and CWGroup.

.. note::

    The webservice types are not autoregistered by the registry, hence an
    explicit registering is needed. The :func:`cubes.wsme.types.scan` function makes things
    easier if many types are defined in the same module.

.. code-block:: python

    from cubes.wsme.types import Base, wsattr, scan

    class CWUser(Base):
        login = wsattr('login', datatype=wsme.types.text)
        password = wsattr('upassword', datatype=wsme.types.text)

        in_group = wsattr('in_group', datatype=['CWGroup'])

    class CWGroup(Base):
        name = wsattr('name', datatype=wsme.types.text)

        users = wsattr('in_group', role='subject', datatype=[CWUser])

    
    def register_callback(vreg):
        scan(vreg, __name__)
