Suds not interpreting WSDL correctly?

[David Hobley]

We are currently experiencing an issue with python Suds plugin, where the wsdl from a
webservice is not being correctly interpreted to construct the XML request submission. The
WSDL and expected XML are simple enough. 




We are running python 2.7, suds 0.4 on Centos kernel 2.6.18-194.11.1.el5 

The issue seems to be that we have a <xsd:sequence> which defines a
<xsd:choice> of 2 elements then a single <xsd:element>. This sequence tag
seems to create an additional parent element around its child elements, so the XML result
is not valid according to the WSDL. 

The XML output we get is: 

<ns0:ProcessOrdersRequest> 
<ns0:profileNote0> <!-- UNDEFINED IN WSDL --> 
<ns0:MarkOrdersPacked> 
<ns0:carrierDetails> 
<ns0:orderId>100</ns0:orderId> 
<ns0:carrier>Carrier1</ns0:carrier> 
<ns0:conNote>123456</ns0:conNote> 
</ns0:carrierDetails> 
</ns0:MarkOrdersPacked> 
<ns0:profileNote0> 
<ns0:note>Nevada Ship Verification process</ns0:note> 
<ns0:noteType>Internal</ns0:noteType> 
</ns0:profileNote0> 
</ns0:profileNote0> <!-- UNDEFINED IN WSDL --> 
</ns0:ProcessOrdersRequest> 


This is not consistent with the object output from the client factory: 

(ProcessOrdersRequest){ 
MarkOrdersPacked = 
(MarkOrdersPacked){ 
carrierDetails[] = 
(CarrierDetails){ 
orderId = "100" 
carrier = "Carrier1" 
conNote = "123456" 
}, 
} 
profileNote0 = 
(ProfileNoteInputType0){ 
note = "Nevada Ship Verification process" 
noteType = "Internal" 
} 
} 


The WSDL request element is defined as: 

<xsd:element name="ProcessOrdersRequest"> 
<xsd:complexType> 
<xsd:sequence> 
<xsd:choice> 
<!-- Mark Orders Packed --> 
<xsd:element maxOccurs="1" minOccurs="1"
name="MarkOrdersPacked" type="tns:MarkOrdersPacked"/> 
<!-- AnotherRequest --> 
<xsd:element maxOccurs="1" minOccurs="1"
name="AnotherRequest" type="tns:AnotherRequest"/> 
</xsd:choice> 
<xsd:element maxOccurs="1" minOccurs="0"
name="profileNote0" type="tns:ProfileNoteInputType0"/> 
</xsd:sequence> 
</xsd:complexType> 
</xsd:element> 


Therefore we expect the XML to be: 

<ns0:ProcessOrdersRequest> 
<ns0:MarkOrdersPacked> 
<ns0:carrierDetails> 
<ns0:orderId>100</ns0:orderId> 
<ns0:carrier>Carrier1</ns0:carrier> 
<ns0:conNote>123456</ns0:conNote> 
</ns0:carrierDetails> 
</ns0:MarkOrdersPacked> 
<ns0:profileNote> 
<ns0:note>Nevada Ship Verification process</ns0:note> 
<ns0:noteType>Internal</ns0:noteType> 
</ns0:profileNote> 
</ns0:ProcessOrdersRequest> 
</ns1:Body> 
</SOAP-ENV:Envelope> 

We have tested the wsdl against SoapUI from eviware.com as well as created a java client
using jaxb which both interpret the wsdl and create an XMLrequest exactly as expected so I
dont expect that there is an issue with the wsdl definition at all. 

Attached is the complete wsdl, XML output and python app. 

Any help appreciated. 

Cheers, 
David

Hallo David,

I am a suds newby who struggled with a similar problem and solved it with
help from somebody on another mailing list.

I would try:

mop.carrierDetails = {'orderId': 100, 'carrier': Carrier1, 'conNote:
'123456'}

Correction:
mop.carrierDetails = {'orderId': 100, 'carrier': Carrier1,
'conNote' : '123456'}

Johann, 

thanks for the pointer; I changed the code as per the attached script. But still see the
same problem in the XML: 

<ns0:ProcessOrdersRequest> 
<ns0:profileNote0> <!-- UNDEFINED IN WSDL --> 
<ns0:MarkOrdersPacked> 
<ns0:carrierDetails> 
<ns0:orderId>100</ns0:orderId> 
<ns0:carrier>Carrier1</ns0:carrier> 
<ns0:conNote>123456</ns0:conNote> 
</ns0:carrierDetails> 
</ns0:MarkOrdersPacked> 
<ns0:profileNote0> 
<ns0:note>Nevada Ship Verification process</ns0:note> 
<ns0:noteType>Internal</ns0:noteType> 
</ns0:profileNote0> 
</ns0:profileNote0> <!-- UNDEFINED IN WSDL --> 
</ns0:ProcessOrdersRequest> 
</ns1:Body>

Does anyone have any ideas what the problem could be here? We are totally stumped and any
help would be gratefully received.

Unfortunately my experience is very limited and my experience is that on
this list the possibility to get expert help is near to zero.

You might try other lists like the soaplib-list where I received
excellent help from somebody after having a similar problem.  I did not
get any help from the python mailing list too.

Johann
