Bug 1444114

This can be addressed adding to the SDK a new Writer.write method that can be used to generate the XML for any SDK object:

  from ovirtsdk4 import types
  from ovirtsdk4 import writer
  from ovirtsdk4 import writers

  vm = types.Vm(
    id='123',
    name='myvm',
    ...
  )

  xml = writer.Writer.write(vm)

  print(xml)

Note that this Writer class (and the equivalent Reader class) are part of the contract of the SDK, and will be kept backwards compatible. But the specific writer and reader classes, for example VmWriter and VmReader, are internal implementation details and they may change at any point without notice. So avoid using them.

I have started to write some code to wrap together services, types and writer.

Declaring a new set can be as simple as :

import ovlib.verb

from ovlib import ListObjectWrapper, ObjectWrapper, wrapper

from ovirtsdk4.types import Event
from ovirtsdk4.services import EventService, EventsService
from ovirtsdk4.writers import EventWriter

@wrapper(writer_class=EventWriter, type_class=Event, service_class=EventService)
class EventWrapper(ObjectWrapper):
    pass


@wrapper(service_class=EventsService, service_root="events")
class EventsWrapper(ListObjectWrapper):
    pass


The relevant code for can be found at :

https://github.com/fbacchella/ovirtcmd/blob/sdk4/ovlib/__init__.py#L193

Remember that the content of the ovirtsdk4.writers package is an internal implementation detail, and that it can change or dissappear at any time without notice.

Until this bug is closed, I have no other choices.
