How to get a filesystem path using Django and JavaScript
I have a server built with Django listening on 127.0.0.1, everything is local and on the same machine (same file system). My client needs to communicate a folder’s path to the server so that the server can launch a script to manipulate what is in that folder. How would I go on about making a GUI in the browser to get that path? I have seen a similar question asked here and the answer suggests that the server exposes the file system in some way so that the client can choose a folder. I understand that this is pretty much the only way to go on about this, but I fail to find a simple implementation of this idea. What I have in mind requires many interactions between the client and the server to update the path as the user progresses in the fs hierarchy. -
Python+Django : I cannot see my rendered data in checkout but I am able to see it in other pages
I have this code: {% for items in items%} <div class="cart-row"> <div style="flex:2"><img class="row-image" src="{{item.product.imageURL}}"></div> <div style="flex:2"><p>{{item.product.name}}</p></div> <div style="flex:1"><p>${{item.product.price}}</p></div> <div style="flex:1"><p>x {{item.quantity}}</p></div> </div> {% endfor %} checkout.html I do not seem to be able to render out the information in checkout.html, but I did so in cart.html using the same code.

Saving data after non-Django Form submission
I have a payment form that is made up of various elements. Here my problem is that the card for a new stripe user isn't registered until after form submission. I know that if my form has a newly added Address, I can use form.is_valid() but that doesn't apply if my address is one that is saved already. But is there a way I can set the card using stripe.PaymentMethod.list after the form is submitted, regardless of if the Django form is part of it? form <form method="POST" id="subscription-form" data-secret="{{client_secret}}"> {% csrf_token %} <label class="block uppercase text-gray-600 text-xs font-bold mb-2">Payment Details</label> {% if payment_methods %} <div class="form-check my-3 bg-gray-200 p-2 rounded-md"> <input class="form-check-input" type="radio" name="payment-methods" id="add-new-card" value="add-new-card" onclick="addCard()" {%if payment_methods %} {%else%}checked="checked" {%endif%} required> <label class="form-check-label" for="add-new-card"> Add new payment method </label> <div id="new-card" style="display: none;"> <label class="block uppercase text-gray-600 text-xs mb-2" for="cardholder-name"> Name on Card </label> <input id="cardholder-name" class="mb-2 border-0 px-3 py-3 placeholder-gray-300 text-gray-600 bg-white rounded text-sm shadow focus:outline-none focus:ring w-full ease-linear transition-all duration-150" value="{{customer.name}}" detype="text"> <!-- placeholder for Elements --> <label class="block uppercase text-gray-600 text-xs mb-2" for="card-element"> Card Details </label> <div id="card-element" class="mb-2 border-0 px-3 py-3 placeholder-gray-300 text-gray-600 bg-white rounded text-sm shadow focus:outline-none focus:ring w-full ease-linear transition-all duration-150"> … -
How do I merge data of two objects in Django REST Framework
So let's say I have this 2 models Poll: class Poll(models.Model): title = models.CharField(max_length=255) is_active = models.BooleanField(default=True) is_available = models.BooleanField(default=True) date_created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title Options: class Option(models.Model): title = models.CharField(max_length=255) poll = models.ForeignKey(Poll, on_delete=models.CASCADE) def __str__(self): return f'{self.poll.title} - {self.title}' These two objects are connected with ForeignKey. Now let's say I have a frontend that renders both options and the question (title of the poll) but I only want make a single API call to the backend. Basically I need the API to looked like this: { "title": "Which is the best frontend framework?", "options":[ { "id": 1, "title": "React" }, { "id": 2, "title": "Vue" }, { "id": 3, "title": "Angular" } ] } How what method/technique should I use to merge two objects like this? -

Faster Django filter querying for very large database
I am creating a geospatial web app and have a very large database, at the moment it is 7.5 million entries long and will be almost 60 million entries long by the time all the data is uploaded. I want to display all the points from a certain date and am simply using Model.objects.filter(datetime__date=requested_date) at the moment. Each date request takes ~8s to load. How can I filter in a more efficient way? If there are better ways to store geospatial data points, I would greatly appreciate any advice! -

NOT NULL constraint failed: core_question.poll_id error
I'm stack on problem with POST method in Django. Core Idea of the project to make Polls, in polls add questions, and for each question to add Answers. I did make all of that. And i have few APIs working: GET: http://127.0.0.1:8000/poll/ Showing all created polls in database GET: http://127.0.0.1:8000/poll/{poll_name}/ // poll_name -> Weather (for example) Showing all questions, all answers and correct answer POST: http://127.0.0.1:8000/api/token/ Providing authorization Token if admin credentials are correct. (username: Admin, password: admin) But now I need APIs for add, remove, update Polls, Questions and Answers. I did try it for Questions first: class Questions(APIView): def get(self, request, format=None, **kwargs): question = Question.objects.filter(poll__title=kwargs['topic']) serializer = QuestionSerializer(question, many=True) return Response(serializer.data) def post(self, request, format=None, **kwargs): serializer = QuestionSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) But i'm getting error: NOT NULL constraint failed: core_question.poll_id error I did try to search it in Internet and its says that i'm not requesting proper parameter's. I did try 100 variations and still cant find what is the problem. This is Github link for project: https://github.com/NeoVic2006/Polls_with_questions_answers Please check it and let me know where is the problem.

Problems with marking djangoo option select labels

Why not use "runserver" for production at Django?
Everywhere i see that uWSGI and Gunicorn are recommended for production mode from everyone. However, there is a lot more suffering to operate with it, the python manage.py runserver is more faster, simpler, and the logging is also more visible if something goes wrong. Still, why not recommend the "python manage.py runserver" command for live production? -
