pycontrol pool.add_member problem

I have a customer who is trying pycontrol and got the following:

 

 

>>> b = pc.BIGIP(

 

... hostname = LTM,

 

... username = USER,

 

... password = PASS,

 

... wsdls = [WSDLS],

 

... fromurl=True

 

... )

 

>>> p = b.LocalLB.Pool

 

>>> p.add_member(

 

... pool_names = ["new_pool"],

 

... members = [[ {'address': '9.9.9.9', 'port': 80 } ]]

 

... )

 

Traceback (most recent call last):

 

File "", line 3, in

 

File "/usr/lib/python2.7/site-packages/suds/client.py", line 539, in __call__

 

return client.invoke(args, kwargs)

 

File "/usr/lib/python2.7/site-packages/suds/client.py", line 598, in invoke

 

result = self.send(msg)

 

File "/usr/lib/python2.7/site-packages/suds/client.py", line 633, in send

 

result = self.failed(binding, e)

 

File "/usr/lib/python2.7/site-packages/suds/client.py", line 684, in failed

 

r, p = binding.get_fault(reply)

 

File "/usr/lib/python2.7/site-packages/suds/bindings/binding.py", line 238, in get_fault

 

raise WebFault(p, faultroot)

 

suds.WebFault: Server raised fault: 'Could not find element by name: address'

 

>>>

 

I cannot figure out for the life of me why address is not showing up as an element in members. Has anyone seen this before? Is it an indication that pycontrol was not set up properly? If so, what part? Thanks.

    After further experimentation, it would appear that somehow the 'address' is not being parsed in my call and the error message is referring to the fact that it can't find the element named address in my list. I also realized that I was using a 64bit version of Python 2.7.2 and that all the examples were done with Python 2.6.4. Is there are a syntax difference between the 2 versions?

    Turns out that the pool member had to be created with the correct structure. The devcentral examples are not quite right.

    >>> member_seq = s.LocalLB.Pool.typefactory.create('Common.IPPortDefinitionSequenceSequence')

     

    >>> member_seq.items = []

     

    >>> new_member = s.LocalLB.Pool.typefactory.create('Common.IPPortDefinition')

     

    >>> new_member.address='1.2.3.4'

     

    >>> new_member.port='80'

     

    >>> member_seq.items.append(new_member)

     

    >>> s.LocalLB.Pool.get_list()

     

    [pool1]

     

    >>> s.LocalLB.Pool.add_member(pool_names=["pool1"], members=[member_seq])

     

    >>> s.LocalLB.Pool.get_member(pool_names=["pool1"])

     

    [[(Common.IPPortDefinition){

     

    address = "1.2.3.4"

     

    port = 80

     

    }]]

     

    >>>

    hey Pat, which examples are not correct? There are changes from v1 to v2 in pycontrol that make them incompatible. v2 is a little more strict with formats but Mr L4L7 swears this is a good thing!
