Django save request.POST to JSONField picks last item from list instead of saving the list
I have a view that receives a post request from client.post() data = { "token": create_hash(customer_name), "images": [image_1, image_2], "name": customer_name, "email": "test@email.com", "phone": "0612345678", "product": "product-sku0", "font_family": "Helvetica", "font_size": 12, "colors_used": ( "#AAAAAA|White D", "#FFFFFF|Black C" ) } I am trying to save the post request as a whole to a model.JSONfield(). The post request key-value pair looks like this: 'colors_used': ['#AAAAAA|White D', '#FFFFFF|Black C'] When I save and later retrieve the value it looks like this: 'colors_used': '#FFFFFF|Black C' Instead of saving the nested list in the JSONfield it only saved the last value.

How to properly override get_queryset in a modelviewset without breaking the query by pk?
I have a ModelViewSet: class OrderViewSet(viewsets.ModelViewSet): serializer_class = OrderSerializer pagination_class = DefaultPagination queryset = Order.objects.all() def get_queryset(self): userId = self.request.query_params.get('userId') if userId is not None: query = Order.objects.filter(owner__id=userId).order_by('-createdAt') else: query = Order.objects.order_by('-createdAt') return query Here is the url registration router = routers.DefaultRouter() router.register('api/v1/order', OrderViewSet, basename='order') I found that after overriding the get_queryset, I can no longer query by one order id like the following anymore: /api/v1/order/1,it just returns detail: not found I do see django saying it supports: ^api/v1/order/$ [name='order-list'] ^api/v1/order\.(?P<format>[a-z0-9]+)/?$ [name='order-list'] ^api/v1/order/(?P<pk>[^/.]+)/$ [name='order-detail'] ^api/v1/order/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='order-detail'] what should be the correct way to do this?

Creating a chart from sentiments of user tweets using chart.js
I’m new to Django. I’m currently doing sentiment analysis on real-time user tweets via Twitter API. I have managed to do the analysis and display the sentiments. Now, I want to visualize the sentiments using charts in my Django app (perhaps bar chart or pie chart) but I’m not sure how. I was thinking of using Chart.js to make it responsive but most of the examples are using static data so I wasn’t successful in integrating my data where I extracted from Twitter API with chart.js. This is a screenshot of my web page. The table was the extracted tweets with their corresponding sentiments. The bar chart however is just static data. I don't know how to convert it into json. enter image description here this is my views.py from django.http.response import JsonResponse from django.shortcuts import render, redirect, HttpResponse from .forms import Sentiment_Typed_Tweet_analyse_form from .sentiment_analysis_code import sentiment_analysis_code from .forms import Sentiment_Imported_Tweet_analyse_form from .tweepy_sentiment import Import_tweet_sentiment from django.contrib.auth.decorators import login_required from django.contrib import messages def sentiment_analysis_import(request): if request.method == 'POST': form = Sentiment_Imported_Tweet_analyse_form(request.POST) tweet_text = Import_tweet_sentiment() analyse = sentiment_analysis_code() if form.is_valid(): handle = form.cleaned_data['sentiment_imported_tweet'] # messages.info(request, 'It might take a while to load the data.') if handle[0]!='#': list_of_tweets = tweet_text.get_hashtag(handle) list_of_tweets_and_sentiments … -

django filter on a large list- giving incorrect count or syntax error on ms sql- filtering in chunks is very slow

How to require an additional charge for the first-time users in stripe subscription?
I am building a Saas project. This system has several pricing plans. The first-time users should pay an additional amount of money. This money is charged only once per account and is not required anymore after the user paid once regardless of the purchased plan. It seems Stripe have no such option. And if I use the normal checkout method and subscription method together, the user should pay twice the first time. This is bad for the user experience. I would be appreciate if you could help me to solve this problem. In addition, I am using Django+React for the project. -
