I am getting this error just in production. On localhost it works well.

AttributeError: 'module' object has no attribute 'Stock'
Stock is one class of my models. I tested with python 2.5 on localhost too.
The line that gives the error is the access to memcache (get function).
I have changed the project and maybe the type of the data I put in memcache is different. Do I have some way to clean the data on memcache?
Any idea?
As of release 1.6.4 there is a Memcache Viewer in the Admin Console. It includes a "Flush Cache" button that should do exactly what you need.
Most likely you have a pickled version of an object in memcache that doesn't match your new code. Here's an old question on flushing memcache, the answer should apply to your case:
How can I have Google App Engine clear memcache every time a site is deployed?

I am trying to use python Zeep library in order to play with some SOAP API. But I can not figure out what is my issue when trying to create the client. Below is a sample of my code:
from requests import Session
from requests.auth import HTTPBasicAuth
from zeep import Client, Settings
from zeep.cache import SqliteCache
from zeep.transports import Transport
from conf.shared_vars import B2B_PROXY, WSDL_PROXY
session = Session()
session.auth = HTTPBasicAuth(B2B_PROXY['key'], B2B_PROXY['secret'])
wsdl = WSDL_PROXY + "SomeServices.wsdl"
client = Client(
wsdl=wsdl,
transport=Transport(
session=session,
cache=SqliteCache(path='./sqlite.db')))
When executing that script, it seems to load data (./sqlite is not empty), but I get the following error (traceback):

AttributeError: 'lxml.etree.QName' object has no attribute 'resolve'
Unfortunately, I do not know what do with this information, what it involves and how to overcome the issue so I can use properly the client!
Thanks for the help you could offer me on this topic.
Well one way to get through this is to modify the involved method in zeep/xsd/types/collection.py:
def resolve(self):
try:
self.item_type = self.item_type.resolve()
except Exception:
print("No resolve method for {}".format(self.item_type))
self.base_class = self.item_type.__class__
return self
This is just a fix and definitly not the best solution, but at least it allows me to use properly Zeep client! I will fill an issue on Zeep GitHub.

I suspect an SQLa update will fix your issue.

I'm having some trouble implementing the Cork library with a Bottle app. I've tried setting up the example app, and I made some minor modifications to get it to run in an WSGI container. The main change is that I changed this:
if __name__ == "__main__":
main()
to this:
application = default_app()
When I authenticate with the admin user, I get the following:

Is there a newbie mistake I might be making? Or is something else wrong?
I figured it out. It was a newbie mistake. The Bottle documentation says that if you want to use Bottle with mod_wsgi, toward the end of the file, you should use this:
application = default_app()
After getting a better understanding of how this all works, I realized I was sending the wrong application object to mod_wsgi. Instead, I should have used this:
application = app #app was defined earlier in the example application
When I try to call Model.put() in Eclipse for a Google Python app, I get the following error:
exception value:[Error 5] Access is denied
I don't know if it's related, but this happened after I changed the parameter of --datastore_path="F:/tmp/myapp_datastore" in arguments of debug configurations.
Everything is working fine for another application from the command prompt.
However, when I use the same in Eclipse I get following dump in the console window of Eclipse:

According to this error,
TypeError: 'str' object is not callable
I guess, you have shadowed built-in object str to something else.
For example, you used str="dummy" in your code and str became uncallable object.
Error 5 generally means the path you specified is wrong. I recommend you to remove the double quotation marks in your command:
Try:
--datastore_path=F:/tmp/myapp_datastore
and let us know if that helped you
