DJANGO - NoReverseMatch at /create/
I am fairly new to Django and for my certification, I am working on cloning Wikipedia. I was able to get the wiki and editing commands to work but having difficulties creating new entries. This is my function to create a new entry: ** Main urls.py** urlpatterns = [ path('admin/', admin.site.urls), path('', include("encyclopedia.urls")) ] urls.py from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path ("wiki/<str:title>", views.entry, name="entry"), path ("edit/<str:title>", views.edit, name="edit"), path ("create/<str:title>", views.create, name="create") ] views.py class Post(forms.Form): title = forms.CharField(label= "Title") textarea = forms.CharField(widget=forms.Textarea(), label='') def create(request, title): if request.method == "POST": form = Post(request.POST) if form.is_valid(): title = form.cleaned_data["title"] textarea = form.cleaned_data['textarea'] entries : util.list_entries() if title in entries: return render(request, "encyclopedia/error.html", { "form": Search(), "message": "Page already exists", "type": "exists" }) else: util.save_entry(title,textarea) page=util.get_entry(title) page_converted = md.convert(page) return render(request, "encyclopedia/create.html", { "form": Search(), 'page': page_converted, "title": title }) else: return render(request, "encyclopedia/create.html", { "form": Search(), "post": Post() }) MY TEMPLATE Creating a new entry {% extends "encyclopedia/layout.html" %} {% block title %} Create {% endblock %} {% block body %} <form method="post" action="{% url 'create' %}"> {% csrf_token %} <h4 class="display-2">Create new page:</h4> <h6 class="post-title">Title: {{post.title}}</h6> {{post.textarea}} <br> <input class="save … -
Django + JS != CSRF
I've found that if i link my html with js in my django project it thow the CSRF verification failed. Request aborted. If I don't link html with that js it works well. So how can I solve this problem? Here is views.py and style.js file: The site is about weather. If I press button to search weather with not linked js it works fine. views.py def index(request): owm = pyowm.OWM(":)") mgr = owm.weather_manager() if(request.method == "POST"): form = CityForm(request.POST) form.save() form = CityForm() city = City.objects.last() result = get_todays_weather(mgr, city.name) forecast_hourly = get_todays_forecast(mgr, city.name) context = { "info": result, "forecast_hourly": forecast_hourly, "form": form } return render(request, "index.html", context) style.js var check = function () { var hours = new Date().getHours(); hours = 3 if (hours < 5 ) { document.getElementById("header_id").style.background = "linear-gradient(to bottom, #692dad, #442aa3)"; document.getElementById("brand_id").style.color = "#f9fbfc"; document.getElementById("body_id").style.background = "#8f7cd6"; document.getElementById("brand_id").style.color = "#f9fbfc"; var elements = document.getElementsByClassName("nav-link"); for(var i = 0; i < elements.length; i++) { if(elements[i].className != "nav-link active") { elements[i].style.color = "#f9fbfc"; } } document.getElementById("search_btn").style.color = "#f9fbfc" document.getElementById("second_card_id").style.background = "linear-gradient(to bottom, #692dad, #442aa3)"; var cards = document.getElementsByName("card"); for(var i = 0; i < cards.length; i++) { cards[i].style.background = "linear-gradient( white 25%, #692dad 50%, white 75% )"; … -
How to disable Django Generics Filters Case-Sensitivity
I'm using Django Generics to get and filter my data. But it's Case-Sensitive and I wounder if there's a way to disable it? for example if I send this request, I don't get any results, because the mail address in the database is Test.test@test.com http://127.0.0.1:8000/api/users/?email=test.test@test.com I tried to use __iexact, but it didn't work!

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. -
DRF - How to get a single item from a QuerySet?
I want to get objects with the pk I send through request but I want only one item from the queryset.

Thanks. -

How to ensure Django updates html to reflect changes?
Expected Result: I expect to see <p>B<p/> when I edit my home page from <p>A<p/> to <p>B<p/>, save changes in the editor, and refresh the browser. Actual Results: I'm seeing <p>A<p/> when I edit my home page from <p>A<p/> to <p>B<p/>, save changes in the editor, and refresh the browser. A week ago I was getting the "Expected results" but I noticed a few days ago I'm getting the results explained in "Actual Results". Now Only when I restart the server by running docker-compose up restart I'm getting the expected results. Why simple HTML changes not being updated when I refresh the browser?

Why does mock patch only work when running specific test and not whole test suite?
I'm using Django and Pytest specifically to run the test suite and am trying to test that a specific form shows up with expected data when a user hits the site (integration test). This particular view uses a stored procedure, which I am mocking since the test would never have access to that. My test code looks like this: #test_integrations.py from my_app.tests.data_setup import setup_data, setup_sb7_data from unittest.mock import patch ... # Setup to use a non-headless browser so we can see whats happening for debugging @pytest.mark.usefixtures("standard_browser") class SeniorPageTestCase(StaticLiveServerTestCase): """ These tests surround the senior form """ @classmethod def setUpClass(cls): cls.host = socket.gethostbyname(socket.gethostname()) super(SeniorPageTestCase, cls).setUpClass() def setUp(self): # setup the dummy data - this works fine basic_setup(self) # setup the 'results' self.sb7_mock_data = setup_sb7_data(self) @patch("my_app.utils.get_employee_sb7_data") def test_senior_form_displays(self, mock_sb7_get): # login the dummy user we created login_user(self, "futureuser") # setup the results mock_sb7_get.return_value = self.sb7_mock_data # hit the page for the form self.browser.get(self.live_server_url + "/my_app/senior") form_id = "SeniorForm" # assert that the form displays on the page self.assertTrue(self.browser.find_element_by_id(form_id)) If I run this test itself with: pytest my_app/tests/test_integrations.py::SeniorPageTestCase The tests pass without issue.

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 … -

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 = … -

How to use reverse filtering and removing duplicates in annotate using Django ORM
Hello I am having flowing model structure class TestModelA(AuditFields, Model): id = models.AutoField(primary_key=True) modelb = models.ForeignKey( TestModelB, on_delete=models.SET_NULL, blank=True, null=True ) class TestModelB(AuditFields, Model): id = models.AutoField(primary_key=True) modelc = models.ForeignKey( TestModelC, on_delete=models.SET_NULL, blank=True, null=True ) class TestModelC(AuditFields, Model): id = models.AutoField(primary_key=True) value = models.charfield(max_length=255, blank=True) I'm making a query like this qs = TestModelA.objects.values('modelb__modelc__value').annotate( count=Count('modelb__modelc__value'), ).distinct() Later some other filters applied to this initial queryset "qs" For that I am having another model class TestModelD(AuditFields, Model): id = models.AutoField(primary_key=True) modela = models.ForeignKey( TestModelA, on_delete=models.SET_NULL, blank=True, null=True, related_name="associated_modela") rating = models.charfield(max_length=255, blank=True) Then this is out new qs qs = (TestModelA.objects.values('modelb__modelc__value').annotate( count=Count('modelb__modelc__value'), ).distinct()).filter(associated_modela__rating = 'Sample') But the issue is that if two TestModelD objects under a single TestModelA object , it duplicating In the above scenario (if two TestModelD objects under a single TestModelA object) Currently I am getting output like this <SoftDeletionQuerySet [{'modelb__modelc__value': 'Large', 'count': 2}]> But my expected output is <SoftDeletionQuerySet [{'modelb__modelc__value': 'Large', 'count': 1}]> -
Transfer Class-based view to another
I created a DetailView class that can receive links from categories or posts from a website. In the “get_object ()” method, I identify if it is Category or Post models (by url slug). The URLs for this class are listed below: /category/ /category/subcategory/ /category/post/ /category/subcategory/post/ The class got too long because the categories and posts have specific behaviors. I was wondering if it is possible to "transfer" one class to another to handle specific information? For example: GenericView redirect to CategoryView after identifying that it is the url: / category / or for PostView, if it is / category / post / NOTE: I am transferring the Wordpress site to Django, so I cannot change the url structure. Is there any way to do this? Do you suggest another better solution? -
