The above was not complete clear. The ovirtsdk4.writer.Writer and
ovirtsdk4.reader.Reader classes are part of the contract of the SDK, it
is safe to use them. The specific writer/reader classes, for example
VmReader or VmWriter, are not part of the contract, and they may change
in the future without notice, so try to avoid using them directly.

Yes that is missing. We have it for reading, but not for writing. This
patch should address that:

  Add generic writer
  https://gerrit.ovirt.org/75699

Please open a bug so that we can decide what version should contain this
fix.

Note that you should try to avoid using directly the writer/reader
classes, as they are an internal implementation detail and may change in
the future. The contract for reading/writing is using the Reader and
Writer classes. For example, to generate the XML for an object (once the
patch is merged):

  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)

[ovirt-users] Missing feature in python SDK4

2017-04-20 Thread Fabrice Bacchella 
I didn't find a way to find the writer that correspond to a given type. Is 
there a way to do that, or it's up to the end user to manually manage this 
mapping ?
