Creating a separate comments app for a django ticket app
Trying to create a separate comments app using class-based views for a ticket project. I think the problem lies in my comments’ models.py or its urls.py file but I dont know how to proceed.

Django application with ASGI Uvicorn increasing the latencies by 4x
We are using a Django application (https://github.com/saleor/saleor) to handle our e-commerce use-cases. We are using ASGI with Uvicorn in production with 4 workers. Infra setup - 4 instances of 4 core 16 GB machines for hosting the Django application (Saleor). The app is deployed using docker on all the instances. 2 instances of 4 core 16 GB for Celery. Hosted PostgresSQL solution with one primary and one replica. Saleor uses Django and Graphene to implement GraphQL APIs. One of the API is createCheckout which takes around 150ms to 250ms depending on the payload entities. While running load test with 1 user, the API consistently gives similar latencies. When number of concurrent users increase to 10, the latencies increase to 4 times (1sec - 1.3 secs). With 20 users, it reaches to more than 10 seconds. Average CPU usage doesn't exceed more than 60%. While tracing the latencies, we found out that the core APIs are not taking more than 150-250ms even with 20 users making concurrent requests. This means that all the latencies are being added at ASGI + Uvicorn layer. Not sure what are we missing out here. From the deployment perspective, we have followed standard Django + ASGI … -

Authenticating users with django in external application
I am creating a project where I have a downloadable software on a clients computer in python. I want to create a login system where I use the users on my django server to authenticate the login on the downloadable software that runs on the clients computer. It is an inventory management system that does some other stuff as well which I am unable to elaborate on. I am unsure what python packages might help with this or where to start. Do I just make my project a webapp or am I able to go with my original idea. I have done quite a lot of searching around to find an answer but haven't found one. This is not a server to server communication that I am looking for but rather a client requesting from the server. This will be a subscription based software and I do not want users accessing the product if they have not paid for their usage. Is this possible? I would appreciate any feedback. -
Cant trigger a view's breakpoint in django tests
I want to debug a view that gets triggered inside a django tests.py Here's the view code: def test_view(request): if request.method == "POST": with open("a_path_to_the_file/aaa.txt", "w") as f: f.write("done!") Here's the test: class ViewsTests(TestCase): def test_add_address(self): self.client.post(reverse("address_book:test_view")) The view just doesn't run in that way. I want the file to be created after I run the test. The breakpoint is set on the if request.method == "POST": line. I use pycharm and run tests via pycharnm run config. -

Django: how to check if the users that are registered under me have new users registered under them in Django
I am writing a referral system logic in django. The referral system works fine now, but what i want to implement is this. When i refer a user "user 2" and "user 3", it is stored that i have refered two users, now how do i check if "user 2" or "user 3" which are refered by me: have gotten a new user refered by them ("user 2" or "user 3").

Grouping entries from PostgreSQL database by their week or month based on timestamp value?
I have been trying to resolve a solution to this for a while now but due to my inexperience with both postgres(and SQL in general) and Django ORM I haven't been able to get a result that I can use. I have this model: class EventItem(models.Model): Id = models.CharField(max_length=200, primary_key=True) StartTime = models.DateTimeField(null=True) EndTime = models.DateTimeField(null=True) Duration = models.TimeField(null=True) Creator = models.CharField(max_length=50, null=True) and I want to get the EventItems and group the entries by their week and/or month. So for every week starting from the earliest entry group all of the events for that week into one group. Right now I am able to return the week number for each individual item by doing this: weeks = EventItem.objects.annotate(week=ExtractWeek('StartTime')).values('week') But this obviously doesn't group the results and I also need to keep the columns from the original table. -
Django authenticate() command returns None
I am doing a website which has Google sign in and I am trying to log in the user when they click the sign in with Google button. This is the code that doesn't work: def google_login(request): security_key = request.GET.get("security_key","") email = request.GET.get("email","") if security_key == "" or email == "": return redirect("/403/") timestamp_now = time.time() try: obj = GoogleSignupToLoginSecurityKey.objects.get(email=email,security_key=security_key) if (timestamp_now-float(obj.timestamp_created)) < 50: print(email) user = authenticate(email=email, password="GOOGLE USER") print(user) if user is not None: login(request, user) else: redirect_url = "/accounts/signup/" return redirect(redirect_url+"?error=google_unknown") return redirect("/accounts/signup/welcome/") else: return redirect("/accounts/signup?error=google_unknown") except: return redirect("/403/") return All the security and timestamp stuff is for security purposes but the bit that doesn't work is the authenticate() command. For this command the email is retrieved by a url parameter and I have checked and it is correct. For a Google Account I have made the password "GOOGLE USER" since I am lazy and haven't bothered taking out the password field for a Google Account, this means that every Google account has the same password but for this type of account it is completely unnessesary to have a password. The command returns "None". Hopefully you understand this and I haven't made it too confusing. -

DJango project & app layout and Imports seem to be extremely repetative
I'm trying to layout my Django app, and I just cannot figure out what the appropriate way to do it is. I've read many questions and blog posts, but nothing seems obvious. Here's my app (I hate the repetition of these terms like buildhealth, but I guess it's idomatic in Django?) - the name of the project, created by django-admin startproject buildhealth and the name of the first app (a performance dashboard) created by django-admin startapp performance is performance): [ROOT] ├── ... ├── buildhealth │ ├── __init__.py │ ├── buildhealth │ │ ├── __init__.py │ │ ├── asgi.py │ │ ├── performance │ │ │ ├── __init__.py │ │ │ ├── ... │ │ │ ├── views.py │ │ │ └── ... │ │ ├── settings.py │ │ ├── urls.py │ │ └── wsgi.py │ ├── ... │ ├── manage.py │ └── staticfiles │ └── ... ├── poetry.lock ├── pyproject.toml └── ... This sort of works, but then i have files all over the place for doing imports which feels terrible. For example - in settings.py, i have to type this: ROOT_URLCONF = "buildhealth.buildhealth.urls" This feels super wrong to have two imports like this. Am I laying this out wrong? … -

redirect to detail view after authentication in django templates

My issue is that right now, when a User clicks login they're redirected to the login page, but after login they don't return to Group they were about to join. Is there a way to sort of stash the url they were at return to it after authentication? This is becoming more important as I add invite links and private groups, where a User is sent a link to join a private Group that isn't displayed on the home page (using {% if group.private != True %} so the User won't be able to return to the Group detail without having to reclick the link they were sent. -
