Retrievel of data from Django Redis Cache is taking great amount of time
I'm trying to use Redis in caching my data so that DB calls are reduced. But the time taken for retrieval from cache is much large than the time which I'm getting when fetching the records without caching. I'm trying to store the django queryset object which consist of around 28k+ records and it's only going to increase as the data increases in the Database.

Private Chat Messaging django Such as facebook
I want to implement a private chat messaging app just like on linkedin or facebook as they have a chat bar on the bottom bar of the screen. I have created the chat application as a different app on the project as the user has to go the messages/ url in order to chat with the user, but in order to make chat boxes like that on facebook home page, do I have to make chat as a separate app or just make the chat app within my main app. I don't have any strategy to it. any help towards the approach would help alot. -

Django RF 405 error for POST request on APIView without ending slash
I'm pretty new to Django Rest Framework and I've been investigating this issue but can't find any solution. I'm pretty sure it will be a small detail but I'm out of idea. I'm using DRF for a project. The team made the choice to not end URL paths with a ' / '. I have an endpoint linked to an APIView with a POST method. We want to do some stuff with a body sent in this POST. However calling it brings (Postman response): 405 Method Not allowed { "detail": "Method \"POST\" not allowed." } Putting a ' / ' at the end of the URL path works (Postman response for normal behavior): { "success": True, "message": "A message returned by the function in APIView" } urls.py from django.urls import path, include from runbook import views from rest_framework.routers import DefaultRouter router = DefaultRouter(trailing_slash=False) router.register(r'my_objects', views.ObjectViewset) urlpatterns = [ path('', include(router.urls)), path('my_objects/myFunction', views.MyFunctionView.as_view(), name="my-function") views.py class MyFunctionView(APIView): """ """ def post(self, request, format=None): try: MyObject.objects.get(slug=slugify(request.data['candidate_name'])) except MyObject.DoesNotExist: return Response(boolean_response(False)) else: return Response(boolean_response(True)) What I read and tried: Wrong type of view: 405 "Method POST is not allowed" in Django REST framework ; 405 “Method POST is not allowed” in Django REST … -
How to correctly setup Global Site Tag (gtag.js) for user_id tracking
I'm trying to implement user_id tracking on my website. I send emails to users with a user_id in their personal link which I need to track. As per the documentation I have added to gtag.js. gtag('config', 'MY_GA_MEASUREMENT_ID', { 'user_id': 'USER_ID' }); But when I go to my website with the following parameters ?user_id=1 I check my Tag Assistent to see which parameters are set and I see the following: uid = USER_ID And no mention at all of user_id or the value I supposedly gave to the parameter. I figured gtag would look for the value in the request but it looks like it accepts the value USER_ID as the string assigned in gtag.js. Does anyone have a clue about how to tackle this? -
Django REST Framework: Can you mix API views with template views?
I am developing a web application using Django and React, and using Django REST Framework to have them talk to each other. I am trying to create a Django view that could handle both AJAX requests from React code AND render Django HTML templates. To accomplish this, I am using the TemplateHTMLRenderer class from Django REST Framework that I found here. However, when I try to fetch() data from that view from React I do not receive any valid response. Here is my view: # URL: "/" class IndexView(APIView): renderer_classes = [TemplateHTMLRenderer] template_name = "dictionary/index.html" def get(self, request, format=None): definitions = Definition.objects.all() return Response({"definitions": definitions}) And here is how I am trying to fetch() datafrom React: componentDidMount() { fetch("/") .then(response => response.json()) .then(data => { this.setState({ definitions: data }); }, error => { this.setState({ alert('ERROR') }); }) } This code ends up displaying the alert "ERROR". Apparently, my view is not returning a valid JSON object. How can I change it to provide both rendering and API functionality? -

That choice is not one of the available choices. Why is this happening?d -

Django get checkbox data list from HTML
I'm pretty sure that this is something basic, but I'm not really sure on how to do this. Anyway, I'm trying to get all of the selected fields from my checklist, but for some reason, it only returns the last one.

Logging in view not done when run via pytest
When my methods in a View class are executed by pytest, the logging statements don't produce any outputs on the console. Is that expected behavior or am I missing something?

Django Celery Progress Bar
I'm using Celery in my Django project and I'm trying to add a progress bar for the status of the progress of the upload of my data. The script is just a simple API upload script. On the celery Git Hub they provide you with a example with a FOR loop using seconds. However, this is hard coding a time frame on the progress bar than actually pulling the status of the actual function in real time. So my question is, how do I make the progress bar pull the actual status of the script ? Id imagine some sort of Java Script will be needed for this. I am not by any means a Java Script expert. So I appreciate any help everyone can give me on this. Thank you so much !

Django incorrect filename encoding on uploading file in FileField

Why v-model not working when used in vue.extend?
I have a page structure similiar to this: <main id="app"> <div id="mount-place"></div> </main> <script type="text/x-template" id="my-template"> ...some code here... <input type="text" v-model="address"> ...some other code here... </script> <script> var ExtendedElement = Vue.Extend({ template: '#my-template', data: function() { return { address: {{ some_address|safe }}; // gets values from django } }, mounted: function() { console.log(this.address); // Works just fine } }); new ExtendedElement.$mount('#mount-place'); </script> ...some unimportant logic here... <script> const app = new Vue({ delimiters: ['[[', ']]'], el: '#app' }); </script> And the problem is it renders just fine, but v-model not working i.e. input shows nothing. When accessing it via console it shows values inside vue object. No errors or warnings. -

Aggregating a subquery with multiple OuterRefs in Django
I'm trying to solve an N+1 selects issue. Currently, the code looks something like this, somewhat simplified - the code is really in a DRF serializer and does some other things: for payment in Payment.objects.filter(...): refunds_total = Payment.objects.filter( batch__merchant=obj.batch.merchant, payment_id=obj.id, payment_type="refund", status="success", ).exclude( tab__is_void=True, ).aggregate( total=Sum('amount') ).get('total', 0.0) # Do something with refunds_total. The performance is really bad. What I'd like to do is something like this: refunds = Payment.objects.filter( batch__merchant=OuterRef("batch__merchant"), payment_id=OuterRef("id"), payment_type="refund", status="success", ).exclude( tab__is_void=True ).aggregate(total=Coalesce(Sum("amount"), 0.0)) return Payment.objects.filter( ... ).annotate(total_refunds=Subquery(refunds)) But Django doesn't allow aggregating in a subquery, as aggregating immediately evaluates the QuerySet. I've tried two approaches. The first is following this documentation. However, I'm not sure how I need to put the query together as there are multiple OuterRefs required. My first shot at a subquery looks like this: refunds = CustomerPayment.objects.filter( batch__merchant=OuterRef("batch__merchant"), payment_id=OuterRef("id"), payment_type="CreditRefund", status="success", ).exclude( tab__is_void=True ).order_by().values( "batch__merchant", "payment_id", ).annotate(total_refunds=Coalesce(Sum("amount"), 0.0)).values("amount") But however I try to get it working, it always returns multiple rows rather than single row with the total, so I can't use it in a subquery. I've also tried making my own Subquery subclass but I couldn't put together anything that worked. -
Django channels: what is an efficient way to implement chat notification system?
Currently I am working on a chat system using django channels and I am not able to find an efficient way to implement chat notification system. Can someone please help me. Any idea is appreciated :) So my problems are how can server notify clients if new messages has arrived when they are not in a chat view ? if we use websocket to send new messages from server to client, does it mean, whenever user is logged in one websocket channel is open for each user ? -how many simultaneous websocket channels/connections can django channels support? do we need to have separate websocket channels for chat notifications and sending actual chat messages? It would be great if someone can share their experiences :) :) - Thank you -
Getting error "Uncaught SyntaxError: Unexpected token o in JSON at position 1" in the front-end
I hope all are fine and safe! I am trying this below requirement where there is a voice synthesizer and it converts my voice (which is a question) into a text and it sends that text to the back-end Django through Ajax. I can see that the backend Django is able to get the value from the front-end and using that to get the value from the db and returning it to the front-end(status code is showing as 200 63) But the problem is that at the ajax success part its not getting the value from the back-end and displaying/speaking it.

def __str__(self) issue - Django
