Embedded link displays when hardcoded but not when passed as variable
I have the following problem in my django project when trying to display an embedded google maps link in my page. This works (renders the Google Maps iframe with a populated map) when I hardcode the src URL but not when I pass it in my context even though they result to the same text string. This is my html detailview.html: {% if maps_link is not None %} <iframe src="https://maps.google.com/maps?q=-28.4457436,21.268374&hl=en&z=14&amp;output=embed" loading="lazy" referrerpolicy="no-referrer-when-downgrade" ></iframe> {% endif %} The src URL as it is shown above displays as I want it to, but when I do the following: {% if maps_link is not None %} <iframe src="{{ maps_link }}" <!-- This gets blocked --> loading="lazy" referrerpolicy="no-referrer-when-downgrade" ></iframe> {% endif %} then my browser gives me the following warning: To protect your security, www.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. This is my views.py where the context is generated. I tried to get around it by applying xframes exemptions but that made no difference: from django.views.decorators.clickjacking import xframe_options_exempt from django.http import Http404, HttpResponse @xframe_options_exempt def detail(request, database_reference): context = { "content" : … -

Django DRF not releasing memory after large response data is send to the front end
I am using Django rest framework in our application's backend. In one of the api end points we have to send a large data as response. So the orm and serialization functionalities takes about 400mb to send the data to the front end. I am using memory_profiler and when we call another api or the same api it shows 400mb at start and then an additional 400mb is used if the same endpoint is called. So total 800mb. It keeps on adding whenever we call the api till it crashes.

react+django questions about https(SSL certificate)
I created a website using react and django. React was used as a front-end, Django was used as a back-end.(React uses S3, and Django uses EC2 server.) I was asked to adapt the website to HTTPS. I know I need to use SSL certificate. However, the front-page running on S3 can use and SSL certificate, so HTTPS is applicable, but the server running on EC2 can't use an SSL certificate. Because EC2 uses IP address, not useing Domain address. There are times when I need to make an API call to "http://my_ip_address/~" on the my website, but it keeps getting blocked. Please help me. How should I solve it? Do I need to add another Domain address to the EC2 server......? Or Is there a way to make a request from HTTPS to HTTP using CORS? I really need your help....! I applied SSL certificate to S3(front-page). But EC2 server is still HTTP. Django "settings.py" file : ... CORS_ALLOW_ALL_ORIGINS = True ... I also applied the above settings. -
How to run django celery tasks with persistent event loop and asyncio calls with proper DB reconnections?
I have a django and celery, postgresql with psycopg2 driver and an external dependency with heavy setup calls which is hard to modify and which saves and reuses asyncio event loop after first invocation. I also have an asyncio call which I need to run in the celery task. This method uses this external dependency internally. It seems that I can't use async_to_sync django call because it doesn't allow me to preserve the loop. Therefore, subsequent tasks executions raise Event loop is closed when I invoke dependency lib calls. I used the following way to handle that: class ExampleModel(models.Model) name = models.CharField() async def my_method(): example_entry = await ExampleModel.objects.aget(id=1) # external async dep call here return example_entry @shared_task(name="example_task", bind=True) def example_task(self): asyncio.get_event_loop().run_until_complete(my_method()) It has worked perfectly for a few months, until we had a restart of the database and connection was lost. All further tasks had django.db.utils.InterfaceError: connection already closed error. Digging in, I created a set of test tasks: @shared_task(name="debug_task_async_to_sync") def debug_task_async_to_sync(self): import asgiref.sync res = asgiref.sync.async_to_sync(my_method)() print("async_to_sync", res) @shared_task(name="debug_task_loop") def debug_task_loop(self): res = utils.get_event_loop().run_until_complete(my_method()) print("loop", res) @shared_task(name="debug_task") def debug_task(): res = models.ExampleModel.objects.get(id=1) print("sync", res) and restarted the database in the time of their execution.

Why do Django custom validation messages not display on the HTML page?

Django Integrity Error instead of Bad Request Error
So I have DRF project using a custom user that extend the AbstractUser, and I want to make the email unique. I tried to change the AbstractUser like this. class AbstractUser(AbstractBaseUser, PermissionsMixin): """ An abstract base class implementing a fully featured User model with admin-compliant permissions. Username and password are required. Other fields are optional. """ username_validator = UnicodeUsernameValidator() username = models.CharField( _("username"), max_length=150, unique=True, help_text=_( "Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only." ), validators=[username_validator], error_messages={ "unique": _("The username already exists."), }, ) first_name = models.CharField(_("first name"), max_length=150) last_name = models.CharField(_("last name"), max_length=150) email = models.EmailField(_("email address"), unique=True, error_messages={ "unique": _("A user with that email already exists."), }) It verified the duplication of the email, but I got Integrity Error, but I want to get Bad Request for my frontend What's wrong, why fields in AbstractUser produce different error for unique constraint?

Using django test fixtures without signals
I am writing code for a web app in python/ django. In the app there is a User model and other models with a OneToOne key to the User model. I want entries in these other models to be created when the user signs up, so I have been using signals. The problem is I am using test fixtures. Some of these fixtures trigger the signal and mean other fixtures are overridden/ not used/ cause integrity errors in the database. How can I make it so that I do not clal signals for these tests, so the database is set up with only my fixtures? (I want to do separate tests while using signals later, but tests with fixtures are non negotiable in my case, so that takes priority). I need to upkeep code quality aswell. Do I change my approach? Error recieved: Integrity error for UNIQUE constraint I have tried Using post_save.disconnect and hten manually loading fixtures with loaddata Overriding the signals using 'with post_save' and then loading fixtures with loaddata -
Error while integrating google OAuth with superset
To integrate Google authentication into my Superset application, which is running on a specific IP address, I followed these steps: Created an OAuth client ID on the Google Cloud Platform. To create it, a JavaScript Authorized Origin is required, which is basically the application's URL. Since my Superset application does not have a domain, I masked the <superset-IP> with a random domain (http://localtesting.com) in my local etc/hosts file. I used this masked domain in the Google Console for creating the client ID. Updated the superset_config.py file with the client ID, client secret, and app domain. Here is the file for your reference: from flask_appbuilder.security.manager import AUTH_OAUTH ENABLE_PROXY_FIX = True AUTH_TYPE = AUTH_OAUTH OAUTH_PROVIDERS = [ { "name": "google", "icon": "fa-google", "token_key": "access_token", "remote_app": { "client_id": "<ClientId", "client_secret": "<ClientSecretKey>", "api_base_url": "https://www.googleapis.com/oauth2/v2/", "client_kwargs": {"scope": "email profile"}, "request_token_url": None, "access_token_url": "https://accounts.google.com/o/oauth2/token", "authorize_url": "https://accounts.google.com/o/oauth2/auth", "authorize_params": {"hd": "http://locatesting.com"} }, } ] AUTH_ROLE_ADMIN = 'Admin' AUTH_ROLE_PUBLIC = 'Public' Restarted the VM where superset is hosted. After completing these steps, I encountered a 502 Bad Gateway error. My Superset application is using an Nginx server. Is this issue somehow associated to nginx or anything wrong in masking of IP in my local machine -

Unexpected Behavior with Concurrent ModelViewset Requests
I'm experiencing an issue with a Django Rest Framework ModelViewSet endpoint named projects/. I have a set of requests (PATCH, DELETE, then GET) that are causing unexpected behavior. The timeline of requests and responses is as follows: PATCH request at 14:45:09.420 DELETE request at 14:45:12.724 3.DELETE 204 response at 14:45:12.852 PATCH 200 response at 14:45:13.263 GET request at 14:45:13.279 GET 200 response at 14:45:13.714 All responses indicate success. However, the GET response, which follows a DELETE, includes the supposedly deleted model. If I call the GET endpoint a bit later, the deleted model is no longer listed. This behavior suggests a potential race condition or a caching issue, where the PATCH operation completes after the DELETE, or the GET request returns a cached list not reflecting the deletion. The view, serializer and model code are all pretty vanilla: class ProjectViewSet(ModelViewSet): parser_classes = (MultiPartParser, FormParser, JSONParser) queryset = Project.objects.all() serializer_class = ProjectSerializer pagination_class = ProjectPagination class ProjectSerializer(serializers.ModelSerializer): creator = UserUUIDField(default=serializers.CurrentUserDefault()) image = serializers.ImageField(required=False) class Meta: model = Project fields = "__all__" class Project(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) creator = models.ForeignKey(User, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) image = models.ForeignKey( wand_image, on_delete=models.DO_NOTHING, null=True, blank=True, related_name="projects" ) One model has a … -

This is my log in view: def login(request): form = formularioLogin() if request.method == "POST": user = authenticate(username = request.POST.get("username"), password = request.POST.get("password")) if user: login_django(request, user) return redirect("calc:index") return JsonResponse({"erro": "Usuário ou senha incorretos."}) return render(request, "cadastro/login.html", {"form": form}) This is my calc:index view: @login_required(login_url="cadastro:login") def index(request): historico = calculos.objects.order_by("-pk") if request.method == "GET": if "apagar" in request.GET: apagar = request.GET.get("apagar") apagar = calculos.objects.filter(pk=apagar) apagar.delete() return render(request, "calc/index.html", {"historico": historico}) elif "conta" in request.GET: conta = request.GET.get("conta") if re.search("^[0-9.+*\-]+$", conta): res = str(eval(conta)) if conta != res: # create = calculos.objects.create(calculo=conta, resultado=res) return render(request, "calc/index.html", {"conta": res, "historico": historico}) return render(request, "calc/index.html", {"conta": res, "historico": historico}) return render(request, "calc/index.html", {"erro": "erro", "historico": historico}) return render(request, "calc/index.html", {"historico": historico}) This is my calc.urls: app_name = "calc" urlpatterns = [ url(r"^$", views.index, name="index"), ] And this is my cmd: CMD I'm using Django … -
