How to overcome "Object of type date is not JSON serializable"?
I am building a booking system, currently i am trying to have unavailable dates displayed in red on a jQuery datepicker. I have composed a view that gets the unavailable dates and saves this to an array. When trying to parse into JavaScript I am getting the following error: "Object of type date is not JSON serializable". I have seen this answered on here, however the solutions I have tried do not seem to be working. In particular I have tried the answers given here: How to overcome "datetime.datetime not JSON serializable"? def unavailable_dates(): confirmed_bookings = Booking.objects.filter(booking_status=1) bookings_max_attendees = confirmed_bookings.values( 'booking_date', 'booking_time').annotate( attendees=Sum('number_attending')).filter(attendees=20) unavailable_dates = [] for booking in bookings_max_attendees: unavailable_dates.append(booking['booking_date']) return unavailable_dates # https://stackoverflow.com/questions/77218397/how-to-access-instances-of-models-in-view-in-order-to-save-both-forms-at-once?noredirect=1&lq=1 def customer_booking(request): if request.method == 'POST': customer_form = CustomerForm(request.POST, prefix='customer') booking_form = BookingForm(request.POST, prefix='booking') if customer_form.is_valid() and booking_form.is_valid(): customer = customer_form.save(commit=False) customer.user = request.user customer.save() booking = booking_form.save(commit=False) booking.customer = customer if limit_no_attendees(booking.booking_date, booking.booking_time, booking.number_attending): booking.save() customer_form = CustomerForm() booking_form = BookingForm() messages.add_message(request, messages.SUCCESS, 'Your booking request was successful, please visit your profile to view the status!') else: messages.add_message(request, messages.ERROR, 'Date and time unavailable!') else: customer_form = CustomerForm(prefix='customer') booking_form = BookingForm(prefix='booking') unavailable_booking_dates = unavailable_dates() dataJSON = json.dumps(unavailable_booking_dates) context = { 'customer_form': customer_form, 'booking_form': booking_form, 'data': … -

Pytest causes 'invalid object name' error while setting up test databases
I'm trying to use Pytest to run unit tests on a Django application, but I'm having trouble interacting with Django's database models. A majority of the models in my application have the managed=False value set, since they're connected to external DBs. I'm using a script that sets the them to managed=True when running the test, because I was having issues with the test DBs being created without any contents. The problem is that whenever I run a test that needs DB access and the system starts creating test databases, it throws an error as soon as it hits one of the tables whose model has been changed to managed=True. Looking at the verbose traceback from Pytest, it seems like the system is trying to query the test database for the entire content of the table in question, and failing because the table doesn't exist. This only happens when one or more models for external have been changed to managed=True, either manually or using the script mentioned earlier. If I don't change any of the models, the test DB creation process works without errors, but the resulting test DBs don't contain any tables. The one model in the application which does … -

Nginx not passing response body from Server 1 to Server 2 when 401 status code with new access token is returned
Question: I'm currently working on a ReactJS application that interacts with multiple backends, including an authentication server using Node.js, another backend using Node.js, and a Django server. Nginx is used to manage requests and distribute them between the front end and these backends. The problem I'm facing arises when I call a backend with an expired access token. In such cases, the authentication server regenerates a new access token and sends it back to the front end. The front end should then make a new request to the same API with this new access token. The challenge lies in how Nginx handles the response from Server 1 (authentication with Node.js) when it is called indirectly from Server 2 (Django). When Server 1 returns a 401 status code along with a new access token in the response body, Nginx doesn't pass this response body to Server 2 or, subsequently, to the frontend. Here's a detailed breakdown of the scenario that doesn't work as expected: Scenario 1 (Problematic): Frontend call to Server 2 (Django) via Nginx, but it has to pass through Server 1 (authentication with Node.js) to check the access token first: Front end calls Server 2 via NGINX. NGINX redirects … -
why can't django return a plain text response with a link to download the file?
I have in Django eksport functionality, in the custom admin. So, when requesting to get everything from the database, I make an ORM query of the necessary sample - the query is heavy, but it works fine, I get the data at once, no more trips to the database. Then comes the functionality of working with this data, shoved everywhere there, processed, and finally shoved into the dataframe pandas and written to a CSV file, and saved in the directory (before that immediately tried to give the user), the file weighs about 280mb. So, what is the actual problem, the real file is saved quickly relatively, but the response to the user can come from half an hour, just with a link to download the file. def save_data_in_csv_file(df_jewelry): """write data Attributes: - df_jewelry: data frame pandas +- 1_300_000 rows.

Deserialization/Serialization DRF
I am interested in understanding which pattern of the below is more aligned with the SOLID principles. Say We have a class CreateView(generics.CreateAPIView) in DRF. Option 1: Single Serializer for serialization/deserialization from rest_framework import serializers class MySerializer(serializers.Serializer): field1 = serializers.CharField()) def to_representation(self, instance): return { 'field1': instance.field1, } Option 2: Create 2 classes MySerializer ( serialize the response I want to create and pass to the response.data ) MyDeserializer ( deserialise my data / perform sanitisation/validation of the incoming request.data ) -

SMTP Authentication error with Gmail and Django

Django - struggling with excessive queries
I need to implement a website menu where every root item can have a dropdown with some more items, and I need to do that using some django models and without any third party tools like mptt. So it will be a tag. So here are the models: class Menu(models.Model): name = models.CharField(max_length=150) class MenuElement(models.Model): name = models.CharField(max_length=100) menu = models.ForeignKey('Menu', on_delete=models.CASCADE) parent = models.ForeignKey('self', null=True, blank=True, on_delete=models.CASCADE, related_name='children') And here is the function that's supposed to do the trick: def draw_menu(menu_name): menu_elements = MenuElement.objects.filter(menu__name=menu_name).select_related('parent') for element in menu_elements: if not element.parent: element.children_list = element.children.all() And here comes the problem. If I get a list of all children of a menu element, it's super easy to display the thing on the web page. But if I leave it like this, there will be an additional query for every root element (to get the children), so 10 elements = 10 queries. And select related cannot really help in here, at least I don't see how to utilize it. 10 queries for a menu is not an option, even 2 is too much, is it possible to do the whole thing using one? Maybe if I redesign the model somehow? -
django-debug-toolbar configure INTERNAL_IPS for docker, compatible ip6
I just got django-debug-toolbar to work in Docker, but with a bit of a hack. The official instructions say if DEBUG: import socket # only if you haven't already imported this hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS = [ip[: ip.rfind(".")] + ".1" for ip in ips] + ["127.0.0.1", "10.0.2.2"] However I saw no toolbar. In my template html I printed {{request.META.REMOTE_ADDR}} and noticed that it was an IP6 address. So I changed the above INTERNAL_IPS logic to if DEBUG: hostname, _, ips = socket.gethostbyname_ex (socket.gethostname()) ips = [ip[:ip.rfind(".")] + ".1" for ip in ips] INTERNAL_IPS += ips INTERNAL_IPS += ['::ffff:'+ip for ip in ips] This works but it feels hacky. Is there a better way to do this? -
find alternative to celery-beat to run slow tasks
I have a problem with a celery task that I have to run every 30 seconds. The task consists of connecting through ModbusTCP to a system to read some values. The problem is that I have to read these values from several systems and in 30s it is not able to finish the execution of all of them. As at the moment I do it is through celery-beat I execute a task that consists of a loop that goes through all the systems to which I have to connect to read the data. The connection attempt sometimes takes a while and that is what causes that in 30 seconds I don't have time to execute the whole loop. Is there any alternative to celery-beat that can fit the functionality I am looking for? Thanks! Try to find a solution for the problem or any alternative to solve my situation -
Django REST Framework Viewset Executes Actions Multiple Times and Shows 'None' for GET Requests

Inbuilt password validator for password reset Django
In the page where the user reset the password (name="password_reset_confirm"), I want to use inbuild django password validator. But unfortunately, I am not able to bring them up on the page. Currently the two password fields are visible and when I change the password, it is working fine but I need to include the password validation that is offered by Django which will check for these below conditions. Your password can’t be too similar to your other personal information. Your password must contain at least 8 characters. Your password can’t be a commonly used password. Your password can’t be entirely numeric. urlpatterns = [ path('admin/', admin.site.urls), path('login/', views.loginPage, name = "user_login"), path('register/', views.registerPage, name="user_register"), path('registration-success/', views.registerSuccessPage, name="register_success"), path('logout/', views.logoutPage, name = "user_logout"), path('', views.home, name = "home"), path('',include('forum.urls')), path('', include('subscription.urls')), path('', include('core.urls')), #password reset path('reset_password/', auth_views.PasswordResetView.as_view(template_name = "password_reset.html"), name="reset_password"), path('reset_password_sent/',auth_views.PasswordResetDoneView.as_view(template_name = "password_reset_sent.html"),name="password_reset_done"), path('reset/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name = "password_reset_confirm.html"),name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name = "password_reset_done.html"),name="password_reset_complete"), ] -

Web stress testing, the pg encountered an exception, TCP/IP connections on port 5432?
I conducted basic stress testing on the django framework, and my View is as follows class HealthCheckView(APIView): def get(self, request, *args, **kwargs): try: Role.objects.filter().count() except Exception as e: return Response(status=499) return Response(status=status.HTTP_200_OK) I use the following command to start the web service: gunicorn myapp.wsgi:application -c myapp/settings/gunicorn.conf.py gunicorn.conf.py content is as follows: bind = f'0.0.0.0:{GUNICORN_PORT}' worker_class = 'eventlet' workers = 6 Then I used the ab tool for stress testing: ab -n 10000 -c 500 https://10.30.7.7/api/v1/healthz/ When the concurrency is 500, the result is good. When I continued to increase the number of concurrent requests, some of them were unable to connect to the database. django.db.utils.OperationalError: could not connect to server: Cannot assign requested address Is the server running on host "10.30.7.7" and accepting TCP/IP connections on port 5432?

Reducing the number of concurrent requests can avoid …
