Hi all,
First of all, thanks for this great tool - it has detected many
serious bugs in my Python code.
Now to the issue at hand: Running pylint 0.18.1 (with Python 2.5.4,
logilab_astng-0.19.1 and logilab_common-0.44.0) for the attached
test.py generates following error (E1101 I believe):
E: 37:DataManager.TestFunc: Instance of 'DataManager' has no 'project' member
This message is generated for the last line of the following
snippet:
class DataManager(object):
def __init__(self):
self.app = get_active_application()
def TestFunc(self):
app = self.app
print app.project
As you can see, it incorrectly reports app as DataManager
instance (it is be Application instance instead - see the attached
file). Also, Application class in fact has a 'project' member
variable.
Code itself has commented-out demonstration how to work around
this error message - essentially it comprises of not using global
function to acquire the Application instance.
Thanks,
Jaakko Salli
