I have write an example. Now it can only add the import module
automatically .
see the attachment.
What about this way to add the NOT_GENERATED codes?
if OK, I will go ahead to add the left NOT_GENERATED codes.
such as how to add an attribute of an class.

Hi all,
Now I'm using the code generation suites of ovirt-engine-sdk, I
find it is very troublesome.
I completely agree with you, automating python entities generation
is on top
of my TODO stack see [1],
Along with this, there was always something more important to do, and
it was delayed time after time, so your help is most welcome.

IMO, we can simplify the process. And I want to engaged in it.
there are two tools parse the api.xsd and generate the params.py
code. They are generateds_gui.py and generateDS.py.
but there still some code can not be generate by these tools. now
we should add these codes manually.
the not NOT_GENERATED codes are as follow in the current
params.py code:
1. import python module
2. a new attribute of GeneratedsSuper class
3. modify the get_root_tag function.
4. modify the parseString function to shut up the stdout.
5. _rootClassMap
6 . _elementToClassMap
7. findRootClass
And I have two ideas about the code generation.
For we should not modify the generateDS.py tools.
But we can improve it.
I think the 1, 2, 3, 7, can be hard-code, and 4, 5 and 6 can be
configured.
So I want to add an configure file to tell how to add the extra
code that are not generated by generateDS.py tools.
And new python program, as extension of generateDS.py to read
the configure file and generate these codes.
sounds good, btw 5,6 can be constructed programmatically using
__all__ generated by generateDS
and finding element name in xsd by type (from __all__).
should all the element name in xsd by type be added to
_rootClassMap, and no element can be exception?
basically yes, cause _rootClassMap is<name, type> holder which used
for (by name) type retrieval,
only exception is if certain type is not referenced by any other
type (then none will look for
it during the type construction), but i would not implement this logic.
Hi Michael,
what's your account on ovirt IRC channel?
seem I can not log on the #ovirt IRC channel.
still some questions.
can I edit the generateDS.py directly in order to generate the
params.py code that we expect. and then rename the generateDS.py, put
it into the SDK directory?
or an new py program to call the functions of generateDS?
Or without the configure file, just make the new python program
that supports an interactive commands.
