wsdl2py requests

I'm trying to get results from a SOAP service called Chrome ADS (for vehicle data). They provided php and Java samples, but I need python (our site is in Django). My question is:

What should I be passing as a request to the SOAP service when using wsdl2py-generated classes?

Following the examples I'm using a DataVersionsRequest object as the request parameter, but the code generated by wsdl2py seems to want a getDataVersions object, and there's something like that defined at the bottom of the generated _client.py file. But that too seems to throw an error. So I'm not sure what I should be passing as the request obj. Any suggestions?

$sudo apt-get install python-zsi
$wsdl2py http://platform.chrome.com/***********
$python 
>>> url = "http://platform.chrome.com/***********"
>>> from AutomotiveDescriptionService6_client import *
>>> from AutomotiveDescriptionService6_types import *
>>> locator = AutomotiveDescriptionService6Locator()
>>> service = locator.getAutomotiveDescriptionService6Port()
>>> locale = ns0.Locale_Def('locale')
>>> locale._country="US"
>>> locale._language="English"
>>> acctInfo = ns0.AccountInfo_Def('accountInfo')
>>> acctInfo._accountNumber=*****
>>> acctInfo._accountSecret="*****"
>>> acctInfo._locale = locale
>>> dataVersionsRequest = ns0.DataVersionsRequest_Dec()
>>> dataVersionsRequest._accountInfo = acctInfo
>>> service.getDataVersions(dataVersionsRequest)

    def getAutomotiveDescriptionService6PortAddress(self):
        return AutomotiveDescriptionService6Locator.AutomotiveDescriptionService6Port_address
    def getAutomotiveDescriptionService6Port(self, url=None, **kw):
        return AutomotiveDescriptionService6BindingSOAP(url or AutomotiveDescriptionService6Locator.AutomotiveDescriptionService6Port_address, **kw)

        kw.setdefault("readerclass", None)
        kw.setdefault("writerclass", None)

        self.binding = client.Binding(url=url, **kw)
        # no ws-addressing

    # op: getDataVersions
    def getDataVersions(self, request, **kw):
        if isinstance(request, getDataVersions) is False:
            raise TypeError, "%s incorrect request type" % (request.__class__)
        # no input wsaction
        self.binding.Send(None, None, request, soapaction="", **kw)
        # no output wsaction
        response = self.binding.Receive(getDataVersionsResponse.typecode)
        return response
.....
getDataVersions = GED("urn:description6.kp.chrome.com", "DataVersionsRequest").pyclass

Also, as an aside, I'm not sure that the strings I'm passing to the pname parameter are correct, I assume that those are the ones I see inside the XML when I explore the service with SOAP UI, right?

It looks like you might be passing a class to service.getDataVersions() the second time instead of an instance (it can't be an instance if it doesn't have __class__).

What's happening is isinstance() returns false, and in the process of trying to raise a type error, an attribute error gets raised instead because it's trying to access __class__ which apparently doesn't exist.

What happens if you try:

>>> dataVersionsRequest = getDataVersions**()**
>>> dataVersionsRequest._accountInfo = acctInfo
>>> service.getDataVersions(dataVersionsRequest)

?

Based on the line:

if isinstance(request, getDataVersions) is False:
            raise TypeError, "%s incorrect request type" % (request.__class__)

it definitely looks like you should be passing an instance of getDataVersions, so you're probably on the right track.

You probably need to be instantiating your definition objects and then populating them. Look for type == pyclass_type objects associated with the request you're wanting to make and instantiate them.

e.g. (just guessing)

>>> versionrequest = getDataVersions()
>>> versionrequest.AccountInfo = versionrequest.new_AccountInfo()
>>> versionrequest.AccountInfo.accountNumber = "123"
>>> versionrequest.AccountInfo.accountSecret = "shhhh!"
>>> service.getDataVersions(versionrequest)

I found that the code generated by wsdl2py was too slow for my purposes. Good luck.
