Hey guys, I've been trying to get suds working but am currently getting
this error:
from suds.client import Client
url='http://ws.tramtracker.com.au/pidsservice/pids.asmx?WSDL'
client = Client(url)
robzy@cookiemonster:/mnt/storage/YarraTrams$ python test.py
Traceback (most recent call last):

robzy@cookiemonster:/mnt/storage/YarraTrams$
Unfortunately I don't really know enough about XML to properly diagnose
the problem, but my Googling suggests that the Doctor(?) object would be
the way to fix it. Unfortunately, I have failed in finding documentation
that is sufficient given my small amount of understanding. Would anyone
have any suggestions?
For reference, the WSDL can be seen at http://pastebin.com/K0PVD0DK
Thanks,

Hey Rob,
You're on the right track. The problem is that the schema references a type defined
in
the schema namespace="http://www.w3.org/2001/XMLSchema" but does not import it.
This is a
fairly common mistake made by the wsdl writer.
This will fix it:
from suds.xsd.doctor import ImportDoctor, Import
url = 'http://ws.tramtracker.com.au/pidsservice/pids.asmx?WSDL'
imp = Import('http://www.w3.org/2001/XMLSchema') # the schema to import.
imp.filter.add('http://microsoft.com/wsdl/types/') # the schema to import into.
d = ImportDoctor(imp)
client = Client(url, doctor=d)
If using suds <= 0.3.9
You may need to clear the suds cache. On linux: 'rm -f /tmp/suds/*'
Or,
client = Client(url, doctor=d, cache=None)
Hope this helps,
Jeff

New subject: Checking for the existence of elements in a response
Hey, a big thanks to Jeff for helping me figure out how to use the
Doctor :) It was much appreciated.
I currently have a bit of a problem, though. I have looked through the
documentation and can't seem to find out what object/ client.service/
returns. This is my code:
result =
client.service.DoSomethingIncrediblyInteresting(WithADiscoStick)
info = result.*FirstField*.SomeTable.SomeData.somethingorother.DooDah
The thing is that sometimes *FirstField *doesnt exist which causes my
Python program to quit rather angrily. Is there a check I can do on
result, FirstField, and so on, to check of the children I'm about to
grab info from actually exist?
Thanks,
Rob.

if hasattr(result, 'FirstField') and hasattr(result.FirstField,
'SomeTable') and hasattr(result.FirstField.SomeTable, 'SomeData') and
so on:
info = that thing

Excellent :) Thank you. That's much nicer than the try/except I was using.

The web is full of discussions about what's best and more pythonic:
- try, except
or
- hasattr
In your example, the provided answer has 3 hasattr and I guess that the
"else" clause is missing. The keys of the dictionary of the class are being
accessed 3 times before doing anything.
With the:
try:
info = result.FirstField.SomeTable.SomeData.somethingorother.DooDah
except AttributeError:
info = somethinElse
you also have a nice way of dealing with it, by letting the code go straight
into fetching values from the dictionary. The advantage is that if any field
down the chain is missing, you catch it, without worrying about extra
"hasattr" in the response.
I guess it depends more on preference and the willigness to be
exception-aware or work more in a standard programming way.
Best regards
Daniel
