How can I add the currently logged in username to the access log of django.server?
I'm trying to add the currently logged in username, if any, to the access log of a Django app: INFO [django.server:161] "GET / HTTP/1.1" 200 116181 ^ username should go here My main problem is how do I share the user/username between the middleware and the filter, since in the filter I don't have access to the request object? I've got a working solution using thread-local for storage, but this doesn't seem like a good idea. Especially since I can't cleanup the value in process_request as it is then cleared too early, before the log line is printed. Solution with threading.local() log.py import logging import threading local = threading.local() class LoggedInUsernameFilter(logging.Filter): def filter(self, record): user = getattr(local, 'user', None) if user and user.username: record.username = user.username else: record.username = '-' return True class LoggedInUserMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): self.process_request(request) return self.get_response(request) def process_request(self, request): from django.contrib.auth import get_user user = get_user(request) setattr(local, 'user', user) django settings MIDDLEWARE = ( ...

Django model relations and dividing models into few tables in larger project

Django: matching query does not exist. Error: 500
I'm trying to find a bug - already a second day. The goal was to create a button to save in-session a piece of information about a particular page that would be "read later". I'm trying to find out why I can't find a match in my query. The id that should be generated in POST is 8, but from what I understand from logs, it's 0. I'm looking for suggestions on how to find out where the problem is. I exchausted all ideas that I had. Additionally, I wonder if is it a good or bad idea that in my views.py I defined called model EssayCls in two functions where I define it with different names. In def get as selected_essay = EssayCls.objects.get(slug=slug), but in def post as post = EssayCls.objects.get(slug=slug).

Reusing a database record created by means of Celery task
There is a task which creates database record {R) when it runs for the first time. When task is started second time it should read database record, perform some calculations and call external API. First and second start happens in a loop In case of single start of the task there are no problems, but in the case of loops (at each loop's iteration the new task is created and starts at certain time) there is a problem. In the task queue (for it we use a flower) we have crashed task on every second iteration. If we add, at the and of the loop time.sleep(1) sometimes the tasks work properly, but sometimes - not. How to avoid this problem? We afraid that task for different combination of two users started at the same time also will be crashed. Is there some problem with running tasks in Celery simultaneously? Or something we should consider, tasks are for scheduled payments so they have to work rock solid -
How do I apply higher permissions to child pages in Wagtail?
I am building an intranet site for my organization with Wagtail and we are in the process of adding a knowledge base. The entire site needs to be restricted to logged-in users, but certain pages need to only be accessible to users in certain groups. For instance, only members of the IT group should be able to access the pages underneath the IT Knowledge Base page. Currently if I set the top-level page to be accessible only by logged-in users, that permission is applied to every page on the site, and I am barred from setting more specific permissions on any child page. It is imperative that I be able to set more specific permissions on child pages. I was able to find Wagtail Bug #4277 which seems to indicate that the logic for more specific permissions is implemented but not exposed in the admin UI. I am not familiar with the inner workings of Wagtail yet, especially how Wagtail permissions intersect with Django permissions. How can I add more specific permissions to child pages? -

React and nginx: refused to connect to localhost

How to sort querysets from different models based on two fields?
I have querysets from different models which have only two fields in common: datetime and dt_created, and I would like to sort the objects first on datetime and then on dt_created, so that objects with the same datetime are sorted based on field dt_created. How can I do that ? Until now I was able to combine and sort the queryset with datetime like this: lst_qs = list(qs_trades) + list(qs_deposits) + list(qs_withdrawals) sorted_lst = sorted(lst_qs, key=lambda x: x.datetime)
