How to avoid duplicate values from queryset
I am having three models class Records(Model): plan = models.ForeignKey(Plan, on_delete=models.CASCADE, related_name="records_plan", null=True) observation = models.CharField(max_length=255, blank=True) description = models.TextField(null=True, blank=True) rating = models.CharField(max_length=255, blank=True) class Plan(Model): plan_title = models.CharField(max_length=255, blank=True) plan_size = models.ForeignKey(Size, on_delete=models.CASCADE, related_name="%(class)s_size", null=True) description = models.TextField(null=True, blank=True) class Size(Model): value = models.CharField(max_length=255, blank=True) order = models.CharField(max_length=255, blank=True) In this I need to draw a chart of plan based on size of the plan my initial queryset is qs = Plan.objects.values('plan_size__value').annotate( count=Count('plan_size__value'), ).order_by("-plan_size__order").distinct() Using this query i'm able to get a queryset with data and field The same queryset I would like to apply a filter on later stages of my code qs = qs.filter(records_plan__rating = 'low') In this case I am getting the output , but values are duplicating (Example, if a plan having two records my chart need to consider it as a single plan , but here it comes as two plans),how to fix this Or how do I get the distinct value of plan while filtering it with record model -
What is the best way to create a website. Django or React Js or Angular Js or Node Js [closed]

Django ASGI/Daphne: postgres connection timeout
In my project I am using a PG database. Now that I've deployed the app to the production server, I' ve switched from the test db (PG 10) to the production db (PG 9). When connecting the Django backend to the test db, everything works perfectly fine, but when I connect it to the production db, it works only for a couple minutes and then, after some time of inactivity for example, the whole site stops working properly. This is the data from daphne: log on imgur What pg settings could cause this? I don't really think that it's an issue with the app's config, because with the other db everything is working correctly. This prod_db is placed on an external server btw. -

How to ensure Django updates html to reflect changes?

Why does mock patch only work when running specific test and not whole test suite?

How to import cache setup into views.py
I have a seperate code for cache creation in another file in my project directory... authentication.py caches_folder = "./.spotify_caches/" if not os.path.exists(caches_folder): os.makedirs(caches_folder) def session_cache_path(): return caches_folder + request.session.get("uuid") oauth = SpotifyOAuth( redirect_uri="http://127.0.0.1:8000/spotify/authorize", scope='user-library-read', show_dialog=True, cache_path=session_cache_path() ) So I am trying to use the oauth in views.py by importing from .authentication import oauth views.py def login(request): if not request.session.get("uuid"): request.session["uuid"] = str(uuid.uuid4()) authorize_url = oauth.get_authorize_url() return redirect(authorize_url) ERROR : return caches_folder + request.session.get("uuid") NameError: name 'request' is not defined I reckon it is because request.session.get("uuid") is defined outside a view but I do not want to be creating oauth in separate views all the time. How do I manage this best? edit: def session_cache_path(uu_id): return caches_folder + uu_id oauth = SpotifyOAuth( redirect_uri="http://127.0.0.1:8000/spotify/authorize", scope='user-library-read', show_dialog=True, cache_path=session_cache_path(uu_id) ) -
how to filter on a field from another Model in nested Serializer
I have the following 3 models (third model Shop not important). There are shops, products, and shopitems (which shop has which item and at which price they offer it). class Product(models.Model): name=models.CharField(max_length=100) class Shopitem(models.Model): product = models.ForeignKey(Product, related_name='shopitems', on_delete=models.CASCADE) price=models.IntegerField() #shop field is not important to my question shop = models.ForeignKey(Shop, related_name='shopitems', on_delete=models.CASCADE) In my ProductSerializer, I made a nested serializer to ShopItemSerialzer, which works great. But how can I get list of all products, which are filtered by the shopitem price? And most importantly, the price is a query parameter, which I will get in my get_queryset() in the viewset, with the GET request 127.0.0.1/?price=500. Similar questions are asked a lot on stackoverflow, but none of them sadly didn't solve it for me. One solution I saw was to add this function to my Product model, and call it from the serializer: class Product(models.Model): name=models.CharField(max_length=100) def some_function(self): return ShopItem.objects.filter(product=self, price__gt=340) class ProductSerializer(serializers.ModelSerializer): shopitems=ShopItemSerializer(many=True, read_only=True,source="some_function") And this works good, but not great. The value 340 that I filter on the price must be hard coded into that function. How can I pass any parameter to it, that I get with self.request.query_params['price'], to this some_function? I also saw other solutions, that … -
Why Django doesn't find a modules which PyCharm finds well?
I tries to build my first Django project. I've created 'superlist' project and 'lists' app inside. My project tree: pycharm_project_folder | superlist | lists superlist manage.py ... | venv My lists/views.py: from django.shortcuts import render def home_page(): """home page""" pass My superlist/urls.py from django.urls import path from superlist.lists import views urlpatterns = [ path('/', views.home_page, name='home') # path('admin/', admin.site.urls), ] My lists/test.py from django.test import TestCase from django.urls import resolve from superlist.lists.views import home_page class HomePageTest(TestCase): """тест домашней страницы""" def test_root_url_resolves_to_home_page_view(self): """корневой url преобразуется в представление домашней страницы""" found = resolve('/') self.assertEqual(found.func, home_page) So, when I run python3 manage.py test I see ModuleNotFoundError: No module named 'superlist.lists' I don't understad why I got it because paths were suggested by PyCharm -
Django passing argument missing ) javascript

Django - Select a specific pk at a view where multiple pk's are available
I'm currently building a support page where people can open each ticket as a box. Problem now is that I need to seperate the pk for each opened suppot ticket where people can reply on as I have everything on a single page and a single view and a single form but with multiple pk's, as all support tickets of the user are getting displayed: def support(request, pk=None): template = 'App_Support/support.html' form = SupportTicketMessagesForm() if request.method == "POST": support_ticket = get_object_or_404(SupportTickets, pk=pk) form = SupportTicketMessagesForm(request.POST) if form.is_valid(): support_ticket_reply = form.save(commit=False) support_ticket_reply.author = request.user support_ticket_reply.content_object = support_ticket support_ticket_reply.save() messages.success(request, 'Reply has been added successfully') return redirect('support') else: messages.error(request, 'Something went wrong') return redirect('support') else: list_support_tickets = sorted( chain( SupportTickets.objects.filter(requester=request.user, status=0) ), key=attrgetter('creation_date'), reverse=True ) paginator = Paginator(list_support_tickets, 10) page = request.GET.get('page') support_tickets = paginator.get_page(page) args = {'support_tickets': support_tickets, 'form': form } return render(request, template, args) My problem is at the following two lines: support_ticket = get_object_or_404(SupportTickets, pk=pk) support_ticket_reply.content_object = support_ticket As I'm unable to properly access the pk of just one object/Support Ticket, as in this view I only have multiple pk's I can potentially reply onto. So how to select? In addition, please also see my models.py logic: referential_models = …
