How to retain a queue of model instances in django to be used accross views (please read description)
I am trying to implement an algorithm as a variation of priority based sorting algorithms used in operating systems. Suppose i have a model Task: class Task(models.Model): priority = 1 name = "task" burst_time = 5 arrival_time = models.DateTimeField(auto_now_add=True) Something like this. And one of my view does something to the task: def my_view(request, pr): instances_queue = Task.objects.filter(priority=pk).order_by(-arrival_time) instance = instance_queue[1] #do something with the instance instance.burst_time = instance.burst_time - 1 instance.save() #if burst_time == 0 dequeue But simply using objects.filter() is not good, so what i ideally need is, to create a class like i have here: class Queue(): def __init__(self, quantum, priority): self.items = [] self.quantum = quantum self.priority = priority def isEmpty(self): return self.items == [] def enqueue(self, item): item.Qtime = self.quantum item.priority = self.priority self.items.insert(0,item) def dequeue(self): return self.items.pop() def size(self): return len(self.items) def peek(self): return self.items[-1] as a model, where items are instances of my Task model. I should be able to make multiple queues and interchange tasks based on needs. The way i am implementing this is getting far too complex. Can someone please help with the design of the Queue model so i can use that as a universal queue for my Task … -
Unable to retrieve individual blog in react using axios
I have spent a couple of time trying to figure out why I'm not able to obtain individual blog post detail page using axios. The code does not return any data (It is returning undefined) I have the follow code: import React, { useState, useEffect } from 'react'; import { Link } from 'react-router-dom'; import axios from 'axios'; export default const blog_detail = (props) => { const [blog, setBlog] = useState({}); useEffect(() => { const slug = props.match.params.id; const fetchData = async () => { try { const res = await axios.get(`https://example.com/blog/${slug}`); setBlog(res.data); } catch (err) { } }; fetchData(); }, [props.match.params.id]); const createBlog = () => { return {__html: blog.body} }; const capitalizeFirstLetter = (word) => { if (word) return word.charAt(0).toUpperCase() + word.slice(1); return ''; }; return ( <div> <div dangerouslySetInnerHTML={createBlog()} /> </div> ); }; The code returns data for those I practice with but never works in my case but everything seems to be similar to theirs. -

Django how to send array to JavaScript for dynamically display pie chart?
I have an array in Django views.py and I want to send it to HTML and display a piechart, but failed, I've tried many other methods and read many tutorials, in most of the case, they have a field in models that store some number, and they display those number. In my case, I need to calculate the subtotal of tasks that are in different states. I'm not sure how to output those data to chart.js with proper labels or any other piechart if there's any recommendation? views.py def visualisation(request, project_id): project = Project.objects.get(id=project_id) counts_data = Todo.objects.aggregate( to_do_count=Count('id', filter=Q(status='to_do')), in_progress_count=Count('id', filter=Q(status='in_progress')), done_count=Count('id', filter=Q(status='done')) ) return render(request, 'todo_lists/progress.html', {"counts_data": counts_data}) html <script> $(document).ready(function() { var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'doughnut', data: { labels: [1,2,3], datasets: [{ label: '# of Votes', data:counts_data, backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)', 'rgba(255, 206, 86, 0.2)' ], borderColor: [ 'rgba(255, 99, 132, 1)', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)' ], borderWidth: 1 }] }, options: { responsive:false } }); }); </script> -
DRF & drf-haystack: How to use prefetched querysets in drf-haystack's serializer
Is there any way to use a prefetched queryset when retrieving information associated with an object in a HaystackSerializer's SerializerMethodField? In a normal DRF view, it is possible to pass prefetched queries to the serializer using prefetch_related or annotate from its own queryset instead of the Search queryset. What should I do in this case? # search_indexes.py class VideoIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) title = indexes.CharField(model_attr="title") published_at = indexes.DateTimeField(model_attr="published_at") def get_model(self): return Video # views.py class VideoSearchView(ListModelMixin, HaystackGenericAPIView): index_models = [Video] serializer_class = VideoSearchSerializer filter_backends = [HaystackFilter, HaystackOrderingFilter] ordering_fields = ["published_at"] def get(self, request, *args, **kwargs): return self.list(request, *args, **kwargs) # serializers.py class VideoSearchSerializer(HaystackSerializer): is_viewed = serializers.SerializerMethodField() is_favorited = serializers.SerializerMethodField() class Meta: index_classes = [VideoIndex] search_fields = ("text",) fields = ( "title", "is_viewed", "is_favorited", "is_wl", ) def get_is_viewed(self, obj): user = self.context["request"].user if user.is_authenticated: try: History.objects.get(user=user, video_id=obj.pk) return True except History.DoesNotExist: pass return False def get_is_favorited(self, obj): user = self.context["request"].user if user.is_authenticated: try: Favorite.objects.get(user=user, video_id=obj.pk) return True except Favorite.DoesNotExist: pass return False -

Django 3.2.8 custom middleware returns 302 redirect errors

How to make a correct redirection in django app after user delete his message in website?
i am developing a website watching a video course and sometimes i don't agree with mentor decisions about solving some tasks. And while i am trying to figure this out, the problem has already taken really much time and i haven't still found how to solve this. At first i show the necessary source code. urls.py and the the error url: path('delete-message/<str:pk>/', views.delete_message, name='delete-message') views.py and function where error happens: @login_required def delete_message(request, pk): message = Message.objects.get(id=pk) room_id = message.room.id if request.method == 'POST': message.delete() return redirect(f'room/{room_id}') ### WHAT DO I HAVE TO DO ??? return render(request, 'delete-message.html') delete-message.html and error form: <form method="POST"> {% csrf_token %} <h2> <p>Are you sure you want to delete this message ?</p> </h2> <a href="{{request.META.HTTP_REFERER}}">Go Back</a> <input type="submit" value="Confirm"> </form> After redirect() works it sends me to the unexisted url: 127.0.0.1:8000/delete-message/10/room/5but it had to be http://127.0.0.1:8000/room/5...

Aggregate and condense time-series values using Django Querysets?
I'm currently trying to create a small crypto tracker for fun using CoinMarketCap's API. The API can be called every 5 minutes – each time returning the current exchange value, however I want to plot my graph in 30-minute intervals. How can I condense my exchange value information of 5-minute increments down to 30-minute data points featuring the respective "Open, High, Low, Close" information? (aka first exchange value, max exchange value, min exchange value, last exchange value) Example data: 2021-10-23 10:00:00 – price: 50 2021-10-23 10:05:00 – price: 45 2021-10-23 10:10:00 – price: 43 2021-10-23 10:15:00 – price: 47 2021-10-23 10:20:00 – price: 51 2021-10-23 10:25:00 – price: 70 2021-10-23 10:30:00 – price: 65 2021-10-23 10:35:00 – price: 55 2021-10-23 10:40:00 – price: 47 2021-10-23 10:45:00 – price: 51 2021-10-23 10:50:00 – price: 62 2021-10-23 11:55:00 – price: 50 Desired output: 2021-10-23 10:00 – open: 50, high: 70, low: 45, close: 57 2021-10-23 10:30 – open: 65, high: 62, low: 47, close: 50 Sample model: class Crypto(models.Model): ticker = models.CharField(max_length=10) price = models.DecimalField(max_digits=7, decimal_places=2) percent_change = models.DecimalField(max_digits=5, decimal_places=2) timestamp = models.DateTimeField(auto_add_now=True) -

Use params or class method for on_delete.SET()? (How to change ForeignKey field on delete)
Is it possible to use SET() for a ForeignKey's on_delete with params and/or a class method? I essentially want to leverage the model or the ForeignKey model to generate a new field. E.g. def create_new_relationship(obj): return obj.relationships.first() class Item(models.Model): name = CharField() relationships = ManyToMany("self", on_delete=SET_NULL) relationship = ForeignKey("self", on_delete=SET( # method with params or # class method possible here? )) def create_new_relationship(self): return self.relationships.first() The only other option I can think of is to add a pre/post-delete signal to Item. -
python django webapp packaging sdist
When I run python setup.py sdist in my project directory and check the contents with tar --list -f .\dist\my_project_name-1.0.tar.gz I see one important python file (manage.py) and a couple of directories templates, which contains .html files, and static, containing .css files, are missing. I've looked at many questions: Q1 Q2 Q3 Q4 but adding a MANIFEST.in or adding the following lines to my setup.py didn't change anything. And what about my manage.py? Shouldn't python files be included by default with sdist? include_package_data=True, data_files=[('templates','my_app/templates/my_app/*.html']), ('static', ['my_app/static/my_app/static/css/*.css'])] Also, I get the same exact result with python setup.py sdist bdist_wheel (although I'm not sure what's the difference with the two commands). -
flow of code from view to serializer class in django rest framework
I am trying to understand the code flow in Django rest framework from view class to serializer class. Like we know if we create an object of a class, the class gets instantiate with that object. And if there are other functions inside that class, we can call that function using the object we just created followed by dot and that function name. It looks something like this. class Person: def __init__(self, name, address): self.name = name self.address = address def details(self): print (f"My name is {self.name} and I live in {self.address}") obj1 = Person("John","London") obj1.details() For example in the above code, when we run obj1= .... , the person class will instantiate with values name and address. And then we can call the details function using the class object that we just created obj1. Now in Django Rest, class LeadsView(APIView): permission_classes = [IsAuthenticated] def put(self, request, pk=None, *args, **kwargs): id = pk abc = Lead.objects.get(id=id) print("before serializer") serializer = LeadSerializer(abc,data=request.data) if serializer.is_valid(): print("after serializer validation") serializer.save() print("after save") return Response({ "message": "Coupon hase been updated", "data": serializer.data }, status=status.HTTP_200_OK) return Response(serializer.data) class Leadserializer(serializers.ModelSerializer): class Meta: model = Lead fields = 'all' def update(self,instance,validated_data): .......... print("iam inside the serializer class") … -
How to fix "assess has been blocked by CORS policy: No 'Access-Control-Allow-Origin' in react
I have a web application with react frontend and django backend. Some of the APIs from the backend are being blocked by cors policy whereas others are not. For example, The API to fetch blog posts const res = await axios.get(`${process.env.REACT_APP_API_URL}/blog/posts`) is returning data but the API for individual posts const res = await axios.get(`${process.env.REACT_APP_API_URL}/blog/${slug}`); is blocked. The register and login APIs are blocked too. I have added the domain to the list of allowed url in settings.py but that didn't solve the issue. The error I'm getting in the detail page is: undefined:1 Access to XMLHttpRequest at 'https://.api.example.co/blog/undefined' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. When I use Postman to test the API's everything works properly. But In react app it's only the API that list posts or items that are returning data, others are blocked. Why such behaviour, and how do I fix it? -
