[Fedora-suds-list] Processing Complex Returns

[Tim Sawyer]

Thanks Jeff.

Oddly, this works on one of my tests:

lResponseParameter = lWebService.execute()
self.assertEqual(lResponseParameter.Person.ID, '196868')
self.assertEqual(lResponseParameter.Person.Firstname, 'Harry')
self.assertEqual(lResponseParameter.Person.Surname, 'Smith')

but not another

lResponseParameter = lWebService.execute()
self.assertEqual(lResponseParameter.ApplicationTrace.Application, False)
self.assertEqual(lResponseParameter.ApplicationTrace.CCode, False)

Not really sure why, I've kind of ignored this for now.  I'll see how it
goes as I develop more tests, see if I can pin down exactly when it
happens.

I'm using execute() to call suds's server.TxnName method, passing in the
correct parameters.  I'm actually trying to write a wrapper so that I can
run these tests both with suds and with iron python as a .net client. 
It's working for basic services, and I'm slowly trying to test some more
complex ones.

I'm now struggling with array type calls.  With my iron python tests, I do
the following in my test to create a list of AgreementStatus objects to
pass to the web service:

lWebService = self.loadWsdl('pdi-web-services.CheckDecision')
lWebService.UserName = 'user'
lWebService.Password = 'password'
lWebService.SecurityToken = None
lAgreementStatus = lWebService.create('AgreementStatus')
lAgreementStatus.AgreementNumber = 'CPP245231'
lWebService.AgreementStatusList = (lAgreementStatus,)
lResponseParameter = lWebService.execute()

With suds this produces XML that looks like this:

<ns0:CheckDecisionCallParameter>
  <ns0:AgreementStatusList>
    <ns0:AgreementNumber>CPP245231</ns0:AgreementNumber>
    <ns0:Decision xsi:nil="true"/>
    <ns0:FailureDateTime xsi:nil="true"/>
    <ns0:FailureReason xsi:nil="true"/>
  </ns0:AgreementStatusList>
  <ns0:Password>user</ns0:Password>
  <ns0:SecurityToken xsi:nil="true"/>
  <ns0:UserName>password</ns0:UserName>
</ns0:CheckDecisionCallParameter>

Which appears to be missing the container XML for each item in the
AgreementStatusList.  I'd expect to see:

<ns0:AgreementStatusList>
  <ns0:AgreementStatus>
    <ns0:AgreementNumber>CPP245231</ns0:AgreementNumber>

as a structure, which is what OxygenXML editor produces when I have it
look at the WSDL and generate XML for the web service call.

How can I get this? (hopefully without changing my test code so that it
breaks the iron python tests!)

Thanks,

Tim.

Hey Tim,

Suds provides an objectification of the XML defined for the service
(method) parameters and returned objects.  So, in this case it looks like
the method returns an ApplicationTrace object (based on the information
you provided).  Assuming you've assigned this to a variable such as:

 >
 > trace = client.service.getApplicationTrace(...)
 >

Then, trace looks like this:

 >
 > print trace
 >

(ApplicationTrace){      <-------- The () indicates that class.
    Application = False
    CCode = False
    CCodeLevel = "0"
    Concurrency = False
    Gateway = False
    GatewayPerformance = False
    Performance = False
    PLSQLCode = False
    Security = False
    TraceOverrideList = ""
  }

So, the following should work:

 >
 > self.assertEqual(trace.Application, True)  >

-or-

 >
 > If trace.Application:
 >  print "The application is true"
 >

.. And so on.

Hopes this helps,

Jeff
