Python suds error creating object

Question

Trying to work with the echosign SOAP API.

The wsdl is here: https://secure.echosign.com/services/EchoSignDocumentService14?wsdl

When I try to create certain objects, it appears to not be able to find the type, even after listing it in print client

import suds

url = "https://secure.echosign.com/services/EchoSignDocumentService14?wsdl"

client = suds.client.Client(url)
print client


  Service ( EchoSignDocumentService14 ) tns="http://api.echosign"
     Prefixes (10)
        ns0 = "http://api.echosign"
        ns1 = "http://dto.api.echosign"
        ns2 = "http://dto10.api.echosign"
        ns3 = "http://dto11.api.echosign"
        ns4 = "http://dto12.api.echosign"
        ns5 = "http://dto13.api.echosign"
        ns15 = "http://dto14.api.echosign"
        ns16 = "http://dto7.api.echosign"
        ns17 = "http://dto8.api.echosign"
        ns18 = "http://dto9.api.echosign"
     Ports (1):
        (EchoSignDocumentService14HttpPort)
           Methods (45):
                 ...
           Types (146):
              ns1:CallbackInfo
              ns17:WidgetCreationInfo

Trimmed for brevity, but showing the namespaces and the 2 types I'm concerned with right now.

Trying to run WCI = client.factory.create("ns17:WidgetCreationInfo") generates this error:

client.factory.create("ns17:WidgetCreationInfo") Traceback (most recent call last): File "", line 1, in File "build/bdist.macosx-10.7-intel/egg/suds/client.py", line 244, in create suds.BuildError: An error occured while building a instance of (ns17:WidgetCreationInfo). As a result the object you requested could not be constructed. It is recommended that you construct the type manually using a Suds object. Please open a ticket with a description of this error. Reason: Type not found: '(CallbackInfo, http://dto.api.echosign , )'

So it doesn't appear to be able to find the CallbackInfo type. Maybe its because its missing the ns there?

Answer 1

Again, figured it out 15 min after posting here.

suds has an option to cross-pollinate all the namespaces so they all import each others schemas. autoblend can be set in the constructor or using the set_options method.

suds.client.Client(url, autoblend=True)

Answer 2

Take a look in the WSDL, it seems lots of definitions in http://*.api.echosign that suds cannot fetch.

Either update your /etc/hosts to make these not well-formed domains can be reached, or save the wsdl locally, modify it, then use Client('file://...', ...) to create your suds client.
