Django redirect not working when I submit my form
My redirect for my login page is not working correctly when I submit a form. def login_page(request): form = LoginForm(request.POST or None) context = { 'form': form, } print(request.user.is_authenticated) if form.is_valid(): username = form.cleaned_data.get("username") password = form.cleaned_data.get("password") user = authenticate(request, username=username, password=password) if user is not None: print(request.user.is_authenticated) login(request, user) # Redirect to a success page. return redirect("login") else: # Return an 'invalid login' error message. print("Error") return render(request, "content/login.html", context) I am expecting it to redirect to same page and print an output that lets me know the authentication worked. But this is what actually happens.. https://i.imgur.com/pFJ5QJH.png Any idea as to what is going on? -

Viewing the result videos of the Machine Learning model on the browser which I can also download, that are stored in different media-storage folder
I have a machine learning model which is capable of doing some video analytics and then finally stores the output videos in a separate folder. I want to run the model every time I upload a new video which goes into a media-storage folder in the project. After the analysis is completed I want to run that result video in the browser and also give a download video option which fetches the video from the media-storage-2 folder where the model will store the result videos. I don't know how to do it. Kindly note that I am developing a Django website and I want the result videos to be displayed and downloaded from there itself. -
Problem with django-RESTframework-Tutorial
I'm trying to get familiar with django-RESTframeworks, therefore I started the official tutorial, to create a Test-API. https://www.django-rest-framework.org/tutorial/quickstart/#quickstart When finally starting the API on my Windows via [CMD] "pyhon manage.py runserver", I get an error code on the command line, which you will see below. I also want to add, that unfortunately, there is some ambiguity in the descriptions in the tutorial, at least from the viewpoint of a beginner, i.e. it's not always certain whether the corresponding code in the tutorial needs to be added in a module or replace all or part of the code in the modules. Therefore, I tried implementing the directions of the tutorial in various ways, always with the same end result. I'm running the code in a virtual env, where i've installed Django 1.11., so there shouldn't be an issue with different Django versions.

How to add selected checkbox options to a models table
I am using django for my web app. I have checkbox options of currency that if selected are to be saved into a models table so that a value can be calculated on submit and used for viewing history.

Persisting django channels groups when deploying to production using multiple server instances
I am deploying my django application that uses web sockets (django channels 2) to production. Using load balancer and two application instances with nginx/gunicorn has been working fine so far but I am wondering about the scalability of the websockets part. How can I build scalable web sockets architecture that will share the django channels groups among different server instances? I am using websockets for the live chat functionality so I have to make sure that users added to a specific group will be able to send/receive message from all other users in the same chat room no matter to which server instance the load balancer will point them. My first thought was to simply use a separate remote server just for redis but I am aware that the vertical scalability will eventually come to an end. What happens when I will need to scale redis servers horizontally? I've been already using the gunicorn + daphne setup but only with low/dev-testing traffic. I have not tried scaling django channels horizontally yet. -
How to pass two different arguments in a single function in django?
Python newbie here, I am trying to create a web-app where shippers can post their truck-loads on sale and accept bids from transporters, and the transporters can post their bids on loads. I have a list view function in my views.py, where a shipper can see all the bids posted by different suppliers, and then he can 'assign' one supplier for that post-load. For that I created this function which takes 2 arguments : the quiz.id (which is the unique primary key of the post-load) and the supplier's ID. urls.py path('confirm/<int:pk>/', teachers.ConfirmRFQ, name='ConfirmRFQ'), views.py @login_required def ConfirmRFQ (request, pk,bi): quiz = Quiz.objects.get(pk=pk) bid = Bid.objects.get(pk=bi) quiz.status = 'Assigned' bid.confirmed = 'Assigned' quiz.save() bid.save() return redirect('teachers:quiz_change_list') The function call in template: <a href="{% url 'teachers:ConfirmRFQ' quiz.pk %}" class="btn btn-primary">Assign</a> Is there something wrong here ? Can I not pass two arguments as such ? Because I keep getting the NoReverseMatch at /teachers/quiz/13/results/ Reverse for 'ConfirmRFQ' with arguments '(13, 33)' not found. 1 pattern(s) tried: ['teachers/confirm/(?P[0-9]+)/$'] error.

Providing "resource" argument to CloudLoggingHandler class does't work

This actually my Django LOGGING handlers settings: 'handlers': { 'stderr': { 'class': 'google.cloud.logging.handlers.CloudLoggingHandler', 'name': "name", 'resource': Resource( type="container", labels={ ... }, ), 'client': google.cloud.logging.Client() }, }, No resource, No problem: 'handlers': { 'stderr': { 'class': 'google.cloud.logging.handlers.CloudLoggingHandler', 'name': "name", 'client': google.cloud.logging.Client() }, }, A simple script works too: import logging import google.cloud.logging # Don't conflict with standard logging from google.cloud.logging.handlers import CloudLoggingHandler, setup_logging from google.cloud.logging.resource import Resource client = google.cloud.logging.Client() logging.getLogger().setLevel(logging.INFO) # defaults to WARN res = Resource( type="container", labels={ ... }, ) handler = CloudLoggingHandler(client, name='name', resource=res) setup_logging(handler) logging.error('logging!')

Sending model updates from db to clients with WSGI
What is the most lightweight way to notify clients of changes to a model table they are viewing? I've used Django Rest Framework to set up an API that serves a templated table of items to clients, and allows them to change buyers on the fly. Currently, I use a recurring jQuery AJAX request with a setTimeout for 2 seconds. This sends a ton of requests and data even when there are no changes, and the webpage size keeps growing. I've had to disable caching as some users might have IE11. I started looking for a way to push the updates to the clients and started exploring Django Channels and Server-Sent-Events. Django Channels Built the demo chat app Very fast Websockets are supported by all my target browsers Seems like overkill for what I'm trying to achieve. Lots of configuration Requires Redis or some other datastore I don't really need the two way communication My app is hosted on Pythonanywhere, which doesn't allow ASGI and doesn't seem to have any plans to do so (1, 2). Server Sent Events Very little information on how to configure this for Django No native support in IE11 or Edge, but there are polyfills … -

Django templating language syntax for navbar notifications
I am trying to use the Django templating language in my Django Channels 2.1.2 project to render out any unread chat messages in a Facebook-style notification popup. The list of unread chatmessages (in their respective threads) and the correct number of notifications are not displaying because I am having trouble with the correct syntax. {{ notification|length }} is displaying the instance of the notification model (which is always 1 for the logged-in user). I think it needs to display the notification_chat field (if the boolean field is set to unread), which is the number of unread messages. Please correct me if I'm wrong. This is how the front end looks. When you click the message icon, the notification disappears. I have a Notification model class Notification(models.Model): notification_user = models.ForeignKey(User, on_delete=models.CASCADE) notification_chat = models.ForeignKey(ChatMessage, on_delete=models.CASCADE) notification_read = models.BooleanField(default=False) def __str__(self): return f'{self.id}' navbar.html {% if user.is_authenticated %} <li id="notification_li" class="nav-item"> <a class="nav-link" href="#" id="notificationLink"> <i class="fas fa-envelope"></i>&nbsp; Inbox</a> <span id="notification_id">{{ notification|length }}</span> <div id="notificationContainer"> <div id="notificationTitle">Notifications</div> <div id="notificationsBody" class="notifications"> {{ notification.notification_chat }} </div> <div id="notificationFooter"><a href="{% url 'chat:inbox' %}">See All</a></div> </div> </li> base.html <script> $(document).ready(function() { $("#notificationLink").click(function() { $("#notificationContainer").fadeToggle(300); $("#notification_id").fadeOut("slow"); return false; }); //Document Click hiding the popup $(document).click(function() { $("#notificationContainer").hide(); … -
