Sending information through Django channels from a view function
I am currently trying to set up a user interface for my app with Django. Basically, I want to send the user updates about what is going on in the backend when he starts a task (do like a loading bar or display the number of steps remaining, for instance) and thought of using Django channels for that. I set up my rooting.py, consumers.py files as well as asgi.py file, and everything is working correctly. However, I want to be able to send the user information through a function in views.py and I am not sure how I can do that, since I don't know how to identify the socket the user is currently connected to from the views.py and how to send information through it. I might be completely wrong using Django channels, maybe there's another (simpler) way of doing so, so I would like to have your advice on that! Thank you! -
selenium tests in django webapp don't work
I'm doing some tests on my django webapp. I install firefox(geckodriver) webdriver in /home/nicola/selenium_drivers/geckodriver, set execution permission and so on.

Django filter using DateTimeField that can be null
I want to filter a table objects using a DateTimeField => last_user_action_time, this field can be null so I need the cases where its null to be included in the result. Here is what I tried: notification_objects = SinglePushNotification.objects.filter( last_user_action_time__lte=day_start, last_user_action_time__isnull=True, ).select_related("customer") This return an empty querySet knowing there is objects where null=True -
Running pyramid and django side by side
We have a pyramid application that provides API endpoint. Now we want to implement frontend as well but to our surprise, i10n/l10n tooling in pyramid is not as good as in django. So I have been thinking what if we implement the frontend with django instead? So I manage to get the PoC running with this code:- # in pyramid main() entry point def main(global_config: t.Dict[str, str], **settings: str) -> Router: """Return a Pyramid WSGI application.""" # Expand environment variables in .ini files settings = expandvars_dict(settings) settings["ini_path"] = global_config["__file__"] # Configure Pyramid config = Configurator(settings=settings) configure(config) # Up, Up and Away! from myapp.wsgi import application as django_app pyramid_app = config.make_wsgi_app() def wsgi_app(environ, start_response): request_url = environ["PATH_INFO"] if request_url.startswith("/api"): return pyramid_app(environ, start_response) return django_app(environ, start_response) return wsgi_app Basically the idea is that, for any request path that starts with /api, we pass it to pyramid, while everything else will be handled by django. This seems to be working well for a simple pages I'm testing, with all the i10n/l10n stuff also working. I'm wondering if there's any gotchas that I should be aware of, if I'm going this route. -

Django Static doesn't load but is accessible. NGINX and Docker
I have connected my Django (DRF) to Gunicorn and Nginx and put it all in docker. When I load mysite.com/admin/ it looks bad, just plain text. So it seems like it does not load any static file. However, in Browser Console there are zero errors. Moreover, I see that all the static files have been successfully loaded from server (all the /static/ requests are HTTP 200) and I can open them right in my browser by putting url: mysite.com/static/admin/css/base.css. And this file will successfully open. But admin site does not want to apply it. On localhost with Debug=True everything is working fine too. On main web site all the /media/ is working good too, so the problem is only within /static/. nginx.conf events {} http { server { listen 80; server_name mysite.com; server_tokens off; location / { return 301 https://$host$request_uri; } } server { listen 80; server_name api.mysite.com; server_tokens off; location / { return 301 https://$host$request_uri; } } server { listen 443 ssl; server_name mysite.com; server_tokens off; ssl_certificate /etc/nginx/certs/mysite.com-chain.pem; ssl_certificate_key /etc/nginx/certs/mysite.com-key.pem; location / { proxy_pass http://10.0.2.237:3004; # React Frontend } } server { listen 443 ssl; server_name api.mysite.com; server_tokens off; ssl_certificate /etc/nginx/certs/api.mysite.com-chain.pem; ssl_certificate_key /etc/nginx/certs/api.mysite.com-key.pem; location /media/ { autoindex on; alias … -

Django Rest Framework is requiring both a session and token to make authenticated request
I'm in the process of creating a REST API using Django Rest Framework for a web application made by a third party. I'm trying to configure the REST API so that it is available using SessionAuthentication or TokenAuthentication and that the Swagger documentation (generated using drf-yasg) is available unauthenticated. The problem I am running into at the moment is that when I send a request to my API it is requiring both a sessionid and token to be sent in the request. If I remove the token I get: {"detail":"Invalid token."} and if I remove the session, it redirects me to the login page of the main application. If I send it with both in the request then I get a valid response from my REST API. My settings.py file looks like the following: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication', #'rest_framework.authentication.SessionAuthentication', ], } As can be seen above, even with SessionAuthentication disabled for the REST API, it still requires the session to be set. Does anyone know why it is doing this? My initial thoughts are that it's using django.contrib.auth and applying that to all views but i'm not sure, i'm a bit of a Django … -

Group by users in django ORM
I've a StudentAnswer model which stores the answer id given by the student(User) in a quiz. If the answer is correct then 1 marks else 0. I'm also ranking the users based on their marks in a particular quiz. The model looks like this: class StudentAnswer(models.Model): user = models.ForeignKey(User, related_name='user_question_answer', on_delete=models.SET_NULL,null=True, blank=True) answer = models.ForeignKey(QuizQuestionAnswer, related_name='user_answer', on_delete=models.CASCADE) quiz = models.ForeingKey(Quiz, on_delete=models.CASCADE) marks = models.IntegerField() This is the query I'm using to rank my users: StudentAnswer.objects.filter( quiz__start_date__month=date.today().month).annotate( rank=Window(expression=DenseRank(), order_by=[F('marks').desc(),]) ) A user will have multiple entries in table(number of questions he attempted in a month). I want to group by each user, add their marks and then rank them for that particular month and send the response. How can I do this? Thanks in advance. -
django-two-factor-auth's user.is_verified() returns False on subdomains
I am facing this strange issue, I have posted it here already but didn't get any response yet. I am using django-two-factor-auth in my Django application, Everything works fine in the local environment but getting an issue on the production server. My application is tenant-based and I am using subdomains for each tenant, for example on the production server, My application => xyz.com User with tenant name "a" after login gets redirected to => a.xyz.com User with tenant name "b" after login gets redirected to => b.xyz.com When redirected to a subdomain I am getting this issue that user.is_verified() always returns False even if 2fa is enabled for the user. I am using user.is_valrified() for showing enable/disable 2fa buttons. If I remove the subdomain redirection, it works fine and returns True if 2fa is enabled for a user. My Environments Browser and version: Google Chrome Version 103.0.5060.114 Python version: 3.8.10 Django version: 2.2.0 django-otp version: 0.9.4 django-two-factor-auth version: 1.12.1 Note: I have debugged this enough that I know this is happening due to sub-domains -

How to **dynamically display** different pages using one html page
I know I have asked this question before but I am really struggling on this issue. I am currently making a shopping website using django and I want to dynamically display the data.

Your code to confirm your email is : {token}", body, 'tadejtilinger@gmail.com', [email] ) return render(request, 'authentication/email/email_confirmation.html', context={'token': token}) return render(request, 'authentication/signup.html') So here I tried to change template from signup.html to email_confirmation.html. I succeeded so now I want to tell python what it should do with email_confirmation.html but I don't know how to do it. If I try writing code under return render(request, 'authentication/email/email_confirmation.html', context={'token': token}) it won't work. Where should I actually write my code then? Thanks for help I hope I wrote question understanding!:) -
How to write test case for a Django model which has all the fields as foreignkey in DRF?
I have a model which has all the fields as a foreign key to other models. How can we create test case in Django rest framework in that case?? I have a model as follows: class Example(models.Model): package = models.ForeignKey( Destination, related_name="packages", on_delete=models.CASCADE ) user = models.ForeignKey( User, on_delete=models.CASCADE, null=True, related_name="user_packages", ) tour = models.ForeignKey( Tours, on_delete=models.CASCADE, null=True, related_name="tour_packages", ) In a model, when there is just one field in a Django model, it can be done in the following way: class NewsLetter(models.Model): NewsLetterID = models.AutoField(primary_key=True) Email = models.CharField(max_length=255) Connected = models.BooleanField(default=False) UserID = models.ForeignKey(User, on_delete=models.CASCADE) class Meta: db_table = 'NewsLetter' @classmethod def setUpTestData(cls): #Set up non-modified objects used by all test methods user = User.objects.create(<fill params here>) NewsLetter.objects.create(NewsLetterID=1, Email='test@test.com', Connected=False,UserID=user) So even if I have created all the objects for all the foreign-key fields just like this example, the thing is, for the related field models, they themselves have foreign key fields. How can we approach this?? For example in my Example model, the Destination model is itself related to other foreign key fields. So how to create unit test for create api for this Example model??
