My site is an Intranet and has hundreds of hits by day. The issue is that django crash some times and I received this trace back error:

And the relevant information is that I have found this on debug data all times that program crash:
'HTTP_USER_AGENT': 'Mozilla/5.0 (BlackBerry; U; BlackBerry 9300; es) AppleWebKit/534.8+ (KHTML, like Gecko) Version/6.0.0.668 Mobile Safari/534.8+',

'HTTP_X_WAP_PROFILE': '"http://www.blackberry.net/go/mobile/profiles/uaprof/9300_edge/6.0.0.rdf"',
App crash in login form. Some ideas?
as you might think, this is no django error.
see https://groups.google.com/group/django-users/browse_thread/thread/946936f69c012d96
have the error myself (but IE ajax requests only, no file upload, just post data).
will add an complete answer if i ever find out how to fix this.

I have following Class to generate a pdf file where I use django-renderpdf to generate a pdf from a html template. But the view is executed twice and an error is thrown.
My class:
class WeeklyMetre(PDFView):
template_name = 'reports/invoice/weekly_metre.html'
allow_force_html = True
prompt_download = True
#property
def download_name(self) -> str:
invoice = Invoice.objects.get(pk=self.kwargs['pk'])
return f"WeeklyMetre_{invoice.invoice_number}.pdf"
def get_context_data(self, *args, **kwargs):
context = super().get_context_data(*args, **kwargs)
invoice = Invoice.objects.get(pk=self.kwargs.get('pk'))
market_labor_specifications = _getWeeklyMetreData(invoice=invoice)
# calculate reported items: reported market_labor_specifications
# invoiced specifications which are validated in invoice-period
# but labor_date before invoice-period
reported_mls = MarketLaborSpecification.objects.filter(invoice_id=self.kwargs.get('pk'), market_labor__labor_date__lt=invoice.period_from) \
.values('market_labor__labor_date', 'specification__position', 'specification__name') \
.order_by('market_labor__labor_date', 'specification__position', 'specification__name') \
.annotate(sum_pos=Sum('validated_quantity'))
context.update({
'invoice': invoice,
'market_labor_specifications': market_labor_specifications,
'reported_mlss': reported_mls
})
print('context data', datetime.datetime.now())
return context
Between the two excutions I have following error:

First of all I don't know why it is executed twice and on the second execution the user is no more authenticated. At the end the pdf is generated well but I cannot apply the LoginRequiredMixin. More informations will be provided if needed and thank you for any help.
Looks like you closed tab in browser or browser stopped to accept response from server in some another way. But web server haven't stopped it's renderring and still generates response, but do not have whom to response. That's why you see:
ConnectionResetError: [Errno 104] Connection reset by peer
After that browser does retry with page reload and you see the second request in logs.
So, you need to understand why it happens. See what browser logs and Dev.Tools will show you (statuses, response and etc.).
P.S. About LoginRequiredMixin - don't know probably some internal things of browser caused with that "retry", but I believe it still should send cookies and session_id.
I believe I've experienced something like this.
The problem is that when you call your endpoint you call it in the URL without a '/' at the end causing DRF to return 301
that redirects you to the same path but with '/' at the end. The problem with that, that after the redirect you lose your headers and cookies and thus become unauthenticated.
That also explains why you can see 2 calls.
So basically if you have a call like this:
api/viewset/dosomethngs
to:
api/viewset/dosomethngs/
Python 2.7.3
Calling an API from a Raspberry Pi 3, the API logs show it hits the correct endpoint and returns with a 200 status code, but the python code from the Pi spits out a huge error stack. I saw in some forums that the ZeroReturnError is always thrown meaning that there was nothing wrong, but that seems weird since I can't actually get the results of the response in an except block from the try.
My code is literally
import requests
response = requests.get(<URL I AM USING>, json={JSON I AM USING})
Not sure what to do.

Some more searching brought me to think it was version issues.
Ran sudo pip install urllib3 --upgrade on the Raspberry Pi and it cleared it up.
I am getting a DependencyWarning about installing PySocks, but its working correctly now.
I'm trying to do some importing to a DB in App Store 1.9.26, in python 2.7.9, and to do so,I would like to get some logging so I can inspect some variables and have a look on whjt is happening
import logging
[...]
updateDueDate = '2016.3.15'
fmt ='%Y.%m.%d'
fechalinea = datetime.datetime.strptime(updateDueDate,fmt)
fecha_aviso = avisoDB.modificacion.due_date.strftime(fmt)
logging.error = ('Date Call= %s, Date DB= %s' %(fecha_aviso, fechalinea))
Which should be pretty straightforward, but its not working. I think I mess up my python instalation or something that has nothing to do with my code, since the output I get from the devserver is:
TypeError("'str' object is not callable",)
TypeError("'str' object is not callable",)

Tried to upgrade python and GAE launcher, google for this problem, but with all the different options I get the same errors, and I'm pretty sure it has nothing to do with my code, but... any one has any idea on what is happening?
Thanks
logging.error = assigns the right-hand-side (in your case, a string) to attribute error of module logging, replacing its previous value (which was a function).
When any Python code (yours or in the SDK) later calls logging.error (which you've set to a string), of course it will produce TypeError("'str' object is not callable",)!
I think I mess up my python instalation
Yes you did, by assigning a string to logging.error.
or something that has nothing to do with my code
It has everything to do with your code -- it's your code that does the mistaken assigning!

a) https://github.com/agfor/braintree-python-appengine . Gave me same error
b) I thought this could be the error from this issue - https://urllib3.readthedocs.org/en/latest/security.html#openssl-pyopenssl
But on updating required libraries , I get stuck at OpenSSL.crypto failed import.
Help anyone!
It looks like braintree is trying to use a socket option unsupported by GAE, you can see a list of supported options here https://cloud.google.com/appengine/docs/python/sockets/ which also states that attempting to get an unsupported option will raise an error
Braintree Version - 3.20.0
Requests version - 2.7.0
With the help of my friend , I used the following hack -
in braintree/util/http.py in the method - __http_do
from google.appengine.api import urlfetch
.....
.....
try:
if http_verb in ["POST", "PUT"]:
result = urlfetch.fetch(url=full_path,
payload=request_body,
method=urlfetch.POST,
headers=self.__headers())
logging.debug('result: %r' % result)
status = result.status_code
response_body = result.content
logging.debug(result.content)
else:
status, response_body = http_strategy.http_do(http_verb, full_path, self.__headers(), request_body)
except Exception as e:
.....
.....
Using this hack, I was able to get things working. Hope this helps anybody coming across the same issue.

Anyone knows the cause for this?
Well, I found out that Facebook Graph API requires IPv6 in a PHP post by Etienne Rached, of all places. Tethering through my mobile phone solved it straight away after that for the development process, and this will be a non-issue when our website is deployed.
I hope this will help someone out there.
