Re: Occasional CSRF cookie not set django 1.11 -> 2.1

[Yusuf Musleh]

Hello Aldian,

Thank you for your reply.

That was one of the very first things we investigated, but it does not seem 
to be the case, as the error happens sometimes when the page/form is still 
fresh, in addition to that, the error message would have been different if 
the token in the form expired, you'd get "CSRF token missing or incorrect.".

I want to mention that it's also not the case where a user is using 
multiple tabs and logs out one of them and then submits a form in another 
tab, those are legitimate errors that should happen, but we are witnessing 
cases where a user opens the website (sometimes for their first time), 
tries to submit a form, and they are not able to because it errors out with 
"CSRF cookie not set."

PostGIS : already installed, but with scripts, not extension

[Not Sqrt]

Hi,


I originally installed PostGiS with :
psql -d template_postgis -f $POSTGIS_SQL_PATH/postgis.sql
and similar commands (
http://postgis.net/docs/manual-2.5/postgis_installation.html#create_new_db).

So not the new method 
http://postgis.net/docs/manual-2.5/postgis_installation.html#create_new_db_extensions

Now, django always wants to run "CREATE EXTENSION IF NOT EXISTS postgis", 
which fails with:
PostGIS is already installed in schema 'public'

Other than commenting the code in 
django/contrib/gis/db/backends/postgis/base.py, is there something else to 
do ?

Thanks a lot !

Re: Occasional CSRF cookie not set django 1.11 -> 2.1

Yusuf, did you use
CSRF_COOKIE_SECURE = True
and access the website using http instead of https?

Re: Occasional CSRF cookie not set django 1.11 -> 2.1

[Yusuf Musleh]

Hi Aldian, thanks for the insight.

We don't set "CSRF_COOKIE_SECURE = True", django defaults it to False, 
allowing cookies to be sent to non https connections, however that being 
said we know that the error occurs even on https.

We redirect all our traffic to https as well.

 Hello,

 We recently migrated from django 1.11.5 to 2.1.4. We performed all the 
 necessary changes needed for the migration and the application to work, 
 things went smoothly except for some CSRF validation issues. After the 
 migration on our production server we noticed an increase in the number of 
 403 errors mainly the `CSRF cookie not set.` error. We added more logging 
 and investigated to see if they were legitimate errors, some are, however 
 we discovered that most aren’t. They were normal users making normal

 should not have failed a day, it happens randomly across random devices, 
 browsers and urls, and has been quite difficult to reproduce.

 We Copy/Pasted the source code of `middleware.csrf` and added it to our 
 code base as a custom middleware to add more logging and get a better 
 traceback in sentry when the error occurs:

 - For some reason the token is not set. `csrf_token = 
 request.META.get('CSRF_COOKIE’)` returns `None`

 - We know that if a user got the error, if they simply refresh the page 
 things would work perfectly fine, this means that setting the token works, 
 but sometimes it does not

 - We know that it is not a problem with our frontend since we also got 
 this error in the django admin including non-login requests

 We also tried clearing all the expired sessions, and set 
 `CSRF_USE_SESSIONS = True`, however nothing changed.

 Also something that might be related, after the migration to 2.1 we 
 started noticing users getting logged out more frequently, with no errors 
 at all, although we set the session to expire in 30 days. We’ve had users 
 complain about occasionally being logged out multiple times in day, again 
 on random devices and browsers.

 Our project is deployed on AWS Elasticbeanstalk running Apache with RDS 
 PostgreSQL 9.6 and CloudFlare DNS/CDN/Cacheing setup.

 We’d appreciate any help or pointers regarding this issue or anywhere 
 we can look at that could be helpful.

 Thanks,

 Yusuf

Re: set python 3.6.8 default in my ubuntu

[Nick Sarbicki]

Hi Omar,

It is generally recommended to _not_ set python3 as your system default.
This is stated in PEP 394
.
The reasoning being there may be internal and third party processes which
still expect the default python to be 2.x. Updating the default to python3
will likely break these and could cause unexpected problems.

You can however create a virtualenv with python3 by simply running *virtualenv
env -p python3*.

It is also worth noting that as far as I know Heroku does support python3.
There is some documentation on this here
.

- Nick

Dealing with global or session objects

[Jean-Noël Colin]

Hi, 

I'm coming from a java world, where there exists different scopes for 
objects: application-, session-, request scopes all define different 
lifecycle for objects. I have some difficulties in finding an equivalent 
approach in Django. 

Here's the need: my project stores its custom configuration in the 
database, for persistence; these parameters can be changed by an 
administrator only, through a custom view/form. However, those parameters 
are used in many views in the project, in read-only mode. So my idea would 
be to have one single object, that stores the parameter values, that is 
initialized when the application starts, that can be read at any time 
without requiring reading from the DB, and that, when modified by admin, 
would be saved to the db. How to plug this in the django architecture? 

Thanks a lot

Jean-Noël

Re: data not coming into html

Why is your shop templates folder outside the shop app folder? You dont
even have any static files folder, niether in shop app nor in cart app. May
be you could manage it first. BTW are you new to django? (just asking)

Re: set python 3.6.8 default in my ubuntu

Hi Omar,

I have added these settings to me ~/.bashrc file in Kubuntu 18.04.
Same would work for rest of the linux with minor changes.
First group would be your answer.
Second groups of lines are used for virtualenv settings
Third group of lines are to make my life easier by saving me typing the
same commands over and over. These are the 3 commands that I use most of
the time.

Write urls without regex in DRF

[Rounak Jain]

I am using DRF Viewsets to auto-generate URLs for different views. Is it
possible to write the code below without using regex?
Thanks

from .views import TaskViewSet
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'', TaskViewSet, basename='task')
urlpatterns = router.urls

Question on logging best practices and ALLOWED_HOST

[Dan Davis]

*First Question - How valuable is the check on ALLOWED_HOST?   *

How many folks out there simply have settings:

ALLOWED_HOSTS = ['*']


*Second Question - What is the best practice for enriching the log record?*

On-premise, we've struggled with the interaction of the AdminEmailHandler 
and security scans:

'mail_admins': {
'level': 'ERROR',
'filters': ['require_debug_false', 
'skip_nessus_scan_requests'],
'class': 'django.utils.log.AdminEmailHandler',
'include_html': True,
},

Now we want to go farther and divert logs originating from the security 
scanner to a different log.

That means that some variant of this code would run again and again:


class SkipNessusScanFilter(logging.Filter):
"""
Avoids a trace back for requests coming from a NESSUS scan.  Depends on 
NESSUS_SCAN_IPS.
"""
def filter(self, record):
request = getattr(record, 'request', None)
if request and hasattr(request, 'META') and 
request.META.get('REMOTE_ADDR') in NESSUS_SCAN_IPS:
return False
return True



I want to centralize the check and make it more performant.   Is there a 
better place to enrich the log record than when the filter runs?

def is_nessus_scan(record):
is_nessus_scan = getattr(record, 'is_nessus_scan', None)
if is_nessus_scan is None:
request = getattr(record, 'request', None)
is_nessus_scan = (request 
  and hasattr(request, 'META') 
  and request.META.get('REMOTE_ADDR') in 
NESSUS_SCAN_IPS)
setattr(record, 'is_nessus_scan', None)
return is_nessus_scan


class SkipNessusScanFilter(logging.Filter):
"""
Avoids a trace back for requests coming from a NESSUS scan.  Depends on 
NESSUS_SCAN_IPS.
"""
def filter(self, record):
return is_nessus_scan(record)


class RequireNessusScanFilter(logging.Filter):
"""
Diverts nessus logging to another file.   Depends on NESSUS_SCAN_IPS.
"""
def filter(self, record):
return not is_nessus_scan(record)

You could also try to check out pyenv . 
It's a pretty handy when dealing with python versions.

Re: My developers have run amok

[Dan Davis]

Sure - setting it up is easy.   There are hard questions about database 
mutations however.   If you drop column bar from table Fubar, then the old 
code is still querying for buth Fu and Bar:

SELECT id, fu, bar FROM fubar 

On-premise, this is the case for maybe 10 seconds, tops.   In the cloud, 
this could be the case for 30 minutes.

We've decided that this is the developers responsibility, and not the 
responsibility of DevOps CI/CD, just like the developer needs to either use 
cache-busting techniques when changing JS and CSS, or educate his users to 
press Shift-F5 when things go wrong.

Show different views based on user

[Rounak Jain]

I am new to Django. Below code returns objects created by the logged in
user. If the user's role property has value 'super', then I want all the
objects to be shown. If the user's role property is 'inter', then I want to
show all objects except objects created by 'super'. Where is the right
place to do this conditional querying?
Thanks

#views.py

class TaskViewSet(ModelViewSet):
serializer_class = TaskSerializer
def get_queryset(self):
return Task.objects.all().filter(created_by=self.request.user)
def perform_create(self, serializer):
serializer.save(created_by=self.request.user)

#serializers.py

class TaskSerializer(ModelSerializer):

class Meta:
model = Task
fields = ('id', 'name', 'status', 'created_by')

normal routes but here in case of drf, it would help if you could show me
how to do it
