'Session' object is not callable? Cannot import anything from Polarion

[mrtnnwmn]

I'm trying to compare pylero to python-polarion, but I've fallen at the first hurdle with pylero. It seems no matter what I try to import, I get a TypeError "'Session' object is not callable".

For example:

import os
os.environ['POLARION_URL'] = 'https://mypolarionurl/polarion'
os.environ['POLARION_REPO'] = 'https://mypolarionurl/repo'
os.environ['POLARION_USERNAME'] = 'myusername'
os.environ['POLARION_TOKEN'] = 'mytoken'
os.environ['POLARION_PROJECT'] = 'myprojectID'
os.environ['POLARION_CERT_PATH'] = os.path.expanduser('~')

from pylero.document import Document

I'm assuming I'm making a basic error in defining the variables so the connection is not made, but I'm not sure what to change?

I can't reproduce the issue, could you add the Traceback log output from the console?

[waynesun09]

@leelavg any idea? This one is not about TestCase object and failed at initiating session.

Nope, I'll check and come back tomorrow. Thanks for the stack trace

• ya, I'm also not able to hit the issue in whatever way (token/passwd, some other variations etc) I try

>>> from pylero.document import Document
> /root/toolbox/pylero/src/pylero/base_polarion.py(299)session()
-> BasePolarion._session = Connection.session()
(Pdb) where
  /root/toolbox/venv/pylero/lib/python3.11/site-packages/bpython/curtsiesfrontend/coderunner.py(185)_blocking_run_code()
[...]
  <bpython-input-19>(1)<module>()
-> from pylero.document import Document
[...]
  /root/toolbox/pylero/src/pylero/document.py(26)<module>()
-> from pylero.work_item import _WorkItem
[...]
  /root/toolbox/pylero/src/pylero/work_item.py(1591)<module>()
-> vals = bp.get_valid_field_values("workitem-type")
  /root/toolbox/pylero/src/pylero/base_polarion.py(1047)get_valid_field_values()
-> project_id = getattr(self, "project_id", None) or self.default_project
  /root/toolbox/pylero/src/pylero/base_polarion.py(30)__get__()
-> return classmethod(self.fget).__get__(instance, cls)()
  /root/toolbox/pylero/src/pylero/base_polarion.py(312)default_project()
-> cls.session
  /root/toolbox/pylero/src/pylero/base_polarion.py(30)__get__()
-> return classmethod(self.fget).__get__(instance, cls)()
> /root/toolbox/pylero/src/pylero/base_polarion.py(299)session()
-> BasePolarion._session = Connection.session()
(Pdb) n
> /root/toolbox/pylero/src/pylero/base_polarion.py(300)session()
-> BasePolarion._default_project = cls._session.default_project
(Pdb)

• In above stacktrace exception is being thrown at ---> 30 return classmethod(self.fget).__get__(instance, cls)() (penultimate), classmethod is resolving the cls to be Session and expection is saying it can't perform function call basically no ()

>>> from pylero.document import Document
> /root/toolbox/pylero/src/pylero/base_polarion.py(31)__get__()
-> return classmethod(self.fget).__get__(instance, cls)()
(Pdb) p self.fget
<function BasePolarion.default_project at 0x7fc43061ea20>
(Pdb) c
> /root/toolbox/pylero/src/pylero/base_polarion.py(31)__get__()
-> return classmethod(self.fget).__get__(instance, cls)()
(Pdb) p self.fget
<function BasePolarion.session at 0x7fc43061e980>
(Pdb) p cls
<class 'pylero.base_polarion.BasePolarion'>
(Pdb) p instance
None
(Pdb) p classmethod(self.fget).__get__(instance, cls)()
<pylero.session.Session object at 0x7fc4304d4fd0>

• @mrtnnwmn would it be possible for you add a print statement above ---> 30 return classmethod(self.fget).__get__(instance, cls)() like print(f'{self.fget=}, {instance=}, {cls=}')
• days passing my python is getting rusty, correct me if there's any mistake in above
• I'm actually confused why Session object isn't callable in the first place, maybe need to look at extra decorators.

PS: pardon the delay, I was unwell for sometime.

[mrtnnwmn]

Sorry for my own delay! I added the print statement and it returned this:

self.fget=<function BasePolarion.default_project at 0x0000027AD2A358A0>, instance=<pylero.base_polarion.BasePolarion object at 0x0000027AD12E7050>, cls=<class 'pylero.base_polarion.BasePolarion'>
self.fget=<function BasePolarion.session at 0x0000027AD2A35800>, instance=None, cls=<class 'pylero.base_polarion.BasePolarion'>

[leelavg]

It looks good to me 😅
