Unsupported WSDL class

[AlthausKonstantin]

Dear All,

I am running in an issue with some of my companies Polarion projects.

Here is a MWE

# %% make my token available
from keyring import get_password
my_token = get_password("polarion", "personal-token")

# %% connect to polarion
from os import environ
environ["POLARION_PROJECT"] = "WHB2019"
environ["POLARION_REPO"] = "https://server.of.my.company/polarion/repo"
environ["POLARION_URL"] = "https://server.of.my.company/polarion"
environ["POLARION_TOKEN"] = my_token

# %% The Problem
from pylero.work_item import Risk  # we have this workitem type
id = 'WHB-52683' # this is an existing workitem
some_risk = Risk(work_item_id=id) # KeyError: 'duration'

I have done some digging...

1. The error occurs in the method get_custom_fields in this linebecause globals() does not contain the key 'duration':

   cls._cls_suds_map[local_name]["cls"] = globals()[parse_type[1]]

2. The key 'duration' turns up here because our workitem type 'Risk' has the custom field type 'Version' which has the type 'ns106:duration':

   cfts = Risk.get_defined_custom_field_types('WHB2019',Risk._wi_type) 
   version_type = cfts[14] # for me the version type is at 14
   print(version_type.name) # prints "Version"
   print(version_type.type) # prints "ns106:duration"

   As we get a type beginning with 'ns', pylero assumes that this type is in the global namespace. (that's what I gleaned from that code-comment) For other Polarion WSDL classes, such as the suds 'Text' from pylero.text, this is also the case.

3. Checking further with the suds client, I also see that the Polarion project in question has this class. This

   print(Risk.session.tracker_client._suds_client)

   produces the following output (here only a shortened version):

   Suds ( https://fedorahosted.org/suds/ )  version: 1.1.2
   
   Service ( TrackerWebServiceService ) tns="http://ws.polarion.com/TrackerWebService"
      Prefixes (5)
       ...
      Ports (1):
         (TrackerWebService)
            Methods (188):
               ...
            Types (74):
               ...
               ns4:duration
               ...

I also looked at the tracker client WSDL resources from Polarion (here) and saw that the duration type is a really simple type wich is essentially equivalent to the base type 'string'. Here is the type definition of the WSDL class:

<simpleType name="duration">
<restriction base="xsd:string"/>
</simpleType>

... but here I need your input

• Do I have to implement the a custom class to handle the WSDL class ns4:duration (analogous to pylero.text?)
• Is there some other workaround?

Thank you for your help!

• I did try my best to get you the answers, however I'm not able to find them

  Do I have to implement the a custom class to handle the WSDL class ns4:duration (analogous to pylero.text?)

• I don't think so, pylero.text is tns2:Text, it's a type which is more analogous to xsd:string for example
• but duration seems to be a simpleType with base:string as a restriction and I'm not sure how this is translated into suds
• however, based on the suds o/p in your listing, duration also seems to be translated to ns and so having that a specific type might work

Is there some other workaround?

• I'm afraid that I don't know this

---

• to be frank my knowledge around your problem space seems to be very limited, I might need to formally look more into how Polarion work items work, pls excuse.

Thank you! No worries, for now I will try to talk to our repo admins maybe we can change the type on the server side. I will let you know if this fixes my problem :)

Ack, in general we might need to look into how suds map simpleType with backing base types and hack into it if possible 🤔

[AlthausKonstantin]

I was able to fix the problem by avoiding the simple types :)

Agreed. In my superficial research I got the impression that suds does not support simple types fully :(
