Django Fulltext search is very slow how to make it fast?
I possess an extensive database of products and aim to implement full-text search functionality to enable users to easily search for products. I've employed SearchVector with Postgres for this purpose; however, the performance is quite sluggish. Despite attempting to enhance speed through indexing, it hasn't yielded the desired results. Below is a snippet of the code I've been working with. models.py class Product(models.Model): brand = models.ForeignKey(BrandName,related_name="brand_products", on_delete=models.CASCADE,db_index = True) item_name_title = models.CharField(max_length=10000, db_index = True,) product_description = models.TextField(db_index = True,) class Meta: indexes = [ GinIndex(fields=['search_vector']), ] Views.py search = request.GET.get('search') search_vector = SearchVector( 'product__mob_sku', 'product__item_name_title', 'product__product_description', 'product__brand__brand_name', ) query = SearchQuery(search) vendor_products = VendorProducts.objects.annotate( rank = (SearchRank(search_vector , query)) ).filter(rank__gte=0.001).select_related( 'vendor', 'product').prefetch_related( 'product__product_images', 'product__brand').exclude( vendor__vendor_name = "ALL_123").order_by('-rank') -
Django: Handling Expired API Keys Without Signals
Title: Django: Handling Expired API Keys Without Signals Question: How can I implement a logic in Django to automatically delete expired API keys from the OutstandingKey model and update the corresponding BlacklistedKey entry when the expiry date has passed, without using signals? I have two Django models: OutstandingKey and BlacklistedKey. The OutstandingKey model represents API keys generated by users, including an expiry date field. The BlacklistedKey model stores blacklisted API keys, referencing the OutstandingKey through a one-to-one relationship. I want to create a system where expired API keys are automatically removed from the OutstandingKey model and added to the BlacklistedKey model when their expiry date has passed. However, I prefer not to use signals for this implementation due to this Django Anti-Pattern. Could someone provide a blueprint or example of how to achieve this logic within Django?. Below is my Models from django.db import models from django.conf import settings from django.utils import timezone class OutstandingKey(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True, default=None, verbose_name="User", ) name = models.CharField(max_length=1000, default="", blank=True, null=True) api_key = models.CharField( max_length=1000, unique=True, verbose_name="API Key", default="", blank=True, null=True, editable=False, ) expiry_date = models.DateTimeField( default=None, verbose_name="Expiry Date", blank=True, null=True ) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name class … -
How to make the price of the product to be dynamically changed in Django?
I'm using Django framework. I've addded product variants like size, color and glass. Now, I need the price to be dynamically changed with selecting product options. The price doesn't change when I'm choosing different options of the product, it remains the same.

Heroku logging for django management commands
I would like to log statements when running a Django management command on Heroku. So, for example, when I login to Heroku and run the command: heroku run bash python manage.py my_management_command I should see all of the logging.info statements included. But instead they don't appear in the Heroku logs. All logging.info statements from the normal django appear fine, just not when I run a management command. My logger setup in settings.py is as follows: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, }, 'loggers': { 'mylogger': { 'handlers': ['console'], 'level': 'DEBUG', 'propagate': True, }, }, 'formatters': { 'verbose': { 'format': '%(asctime)s - %(name)s - %(levelname)s - %(message)s' }, }, } Can anyone tell me how to get log statements from inside my django management command to appear in the heroku logs? -
django using APIView can't override default djangorestframework permission classes
I'm trying to add swagger to my app, like stated here: https://django-rest-swagger.readthedocs.io/en/latest/schema/#advanced-usage So I've added this: class SwaggerSchemaView(APIView): permission_classes = [AllowAny] renderer_classes = [ renderers.OpenAPIRenderer, renderers.SwaggerUIRenderer ] def get(self, request): generator = SchemaGenerator() schema = generator.get_schema(request=request) return Response(schema) I have the following lines in my settings.py: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_simplejwt.authentication.JWTAuthentication', ), 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ) } When I go to swagger url, I get this: HTTP 401 Unauthorized Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept WWW-Authenticate: Bearer realm="api" { "detail": "Authentication credentials were not provided." } But I am expecting permission_classes to override the default ones.

How can I resolve ModuleNotFound Error in Django?

How to Embed google review in Django website?
I was going through the Google Cloud Platform Console to find out how I could embed a Google review on my Django website. I found the Google Places API to be the most relevant (not quite sure), but then I got lost with all the details, pricing, and different tiers. My case is actually quite simple. I just want to display the total number of stars a specific place has. Is there a free way to get that, which I didn't understand? -
Portable windows app built with electron-builder takes too long to start up
I have used electron-builder to package my React + Django application into a single executable file. When I build the app, the resulting dist folder contains: -- dist (folder generated after building the app with electron) | |- MyApp0.0.1.exe (portable exe file) | |- win-unpacked | | | |-MyApp.exe | |-multiple_folders (dependencies of the MyApp.exe) | |-multiple_files (dependencies of the MyApp.exe) The problem is the following: When runnning the MyApp.exe inside the win-unpacked folder, and as long as the dependency files/folders are at the same level, the app works perfectly fine and takes less than a second to startup and display. It even asks for admin password, as in the package.json config it is specified to build it with "requestedExecutionLevel": "highestAvailable". When running the MyApp0.0.1.exe which is supposed to be the portable, standalone .exe file for the application, although it does run perfectly fine, it takes up to 6 minutes to start-up and display the app. I have tried skimming down the project as much as possible in terms of the node_modules that I need, removing large data files not needed, ... I am clueless as to why this is happening. I am not a web-dev expert in any way … -

Sending and receiving custom signals in Django and ensuring it is atomic
I want to create a custom signal and send the signal after some database operations. The receiver also performs database operations. I want to make sure all the database operations before sending the signal and in the signal, receiver is atomic meaning either all fail, or all succeed. Consider the following code: def send_my_signal(): # Database operation 1 # Database Operation 2 my_signal.send(sender=MyModel) The receiver: @receiver(my_signal) def my_receiver(sender, **kwargs): # Database operation 3 # Database operation 4 I want either all database operations 1 to 4 succeed or fail together. By asking from generative AI models, one proposed solution is to wrap the body of the function that performs database operations and sends the signal inside the transaction.atomic() context manager. So, the code would look like this: def send_my_signal(): with transaction.atomic(): # Database operation 1 # Database Operation 2 my_signal.send(sender=MyModel) But I could not find any resource or anything in Django documentation confirming this. It's not like I am calling the receiver of the signal inside the transaction.atomic() context manager, I am just sending the signal there. -
Optimizing One-to-Many Joins in Django MySQL ORM for Better Data Presentation
In Django MySQL ORM, I wanted to join tables with one-to-many relations. Consider a scenario where one user can belong to more than one department. Users and Departments are different entities. Now, if I want to demonstrate the rows as, User columns and department names the user belongs to in a single column as a list. How do I do that most efficiently? Example: class User(models.Model): name = models.CharField(max_length=100) class Department(models.Model): name = models.CharField(max_length=100) user = models.ForeignKey(User, on_delete=models.CASCADE) Output: [ {'id': 1, 'name': 'John', 'department_names': ['HR', 'IT']}, {'id': 2, 'name': 'Alice', 'department_names': ['Finance']} ] I tried this: queryset = User.objects.values( 'id', 'name', ).annotate( department_names=Concat( 'department__name', Value(', '), output_field=CharField(), ) ).filter( department__isnull=False ).distinct() But got this: <QuerySet [ {'id': 1, 'name': 'John', 'department_names': 'HR, '}, {'id': 1, 'name': 'John', 'department_names': 'IT, '}, {'id': 2, 'name': 'Alice', 'department_names': 'Finance,'} ]> Expecting something this: <QuerySet [ {'id': 1, 'name': 'John', 'department_names': 'HR, IT'}, {'id': 2, 'name': 'Alice', 'department_names': 'Finance'} ]> -
Validate Django `JSONField` values are dictionaries
Is there anyway to require that a Django JSONField stores dictionary values only? And throws an error on scalar values. For example, I want the following values to be valid: {} {"a": 1} {"a": 1, "b": 2} And I want the following values to be invalid: "hello world" True 1 JSONField currently accepts all of these values, which makes sense because they're all valid json. But I want to change that behavior. -
How do I reduce the number of connections requests created by a multithreaded Django request?
My project is roughly set up like this thread_pool = ThreadPoolExecutor() def my_background_thread(model: MyModel): # Other DB Reads here ... # Some long running action here, spawning several threads ... # Save result of action to DB model.field = val model.save() # Other DB writes ... def my_view(request): model = MyModel.objects.get(...) thread_pool.submit(my_background_thread, model) # Return before thread has completed return HttpResponse("success") Unfortunately, because of the way I've set it up, Django is creating far too many DB connections -- more than necessary and exceeding my DB limits. Some things that are not clear: When I pass model to the new thread, does it create a new connection at that point? Does it create a new connection only when I read / write to the model? Only when I write? How do I check the number of open connections, or show when a connection is created? In short, how can I prevent Django from creating too many connections in this scenario? -
Emulating an empty queryset with an abstract model
I have a use case in which I have a ListAPIView that connects to a 3rd party (Stripe) API, fetches data (invoices) and returns that data to the user. I have a serializer, but I don't have a model. The entire code looks something like this: class InvoicesList(generics.ListAPIView): serializer_class = InvoiceSerializer def get_queryset(self): if getattr(self, 'swagger_fake_view', False): return # <---- ¿?¿?¿?¿?¿?¿?¿?¿? return StripeWrapper().get_invoices() class InvoiceSerializer(serializers.Serializer): ...fields.. ...fields... ...fields class StripeWrapper(): def get_invoices(): return requests.get(......) Since I don't have a model, drf-spectacular refuses to generate the proper openapi specs. It expects to receive an EmptyQuerySet (SomeModel.objects.none()), but I can't provide it any since I don't have an Invoice model. I could create an abstract model like this: class Invoice(models.Model): class Meta: abstract = True but I still won't be able to provide drf-spectacular with an Invoice.objects.none() since there is no manager in that class (and there can't be since it's abstract). How can I "emulate" (¿?) or "generate" an EmptyQuerySet so I can workaround this issue? -

I want to know certain things like , where are the credentials searched for the authentication. I don't know any of that and that's the reason I want to print some things in the code. First question is, can I do that ? I always have learned coding with actually doing the things from the very basics, looking for what is happening with the code . The second question is that im trying to run the code but it gives me an error : django.core.exceptions.ImproperlyConfigured: Requested setting AUTHENTICATION_BACKENDS, but settings are not configured.

Django | NOT NULL constraint failed | When trying to reverse migrations

I realized after that I can't just re-migrate a models.OneToOneField in the same way I had originally and it started to throw the error "django.db.utils.IntegrityError: UNIQUE constraint failed:" this being because I was trying to re-migrate a models.OneToOneField back into my model I didn't think this was a huge issue, I was just going to reverse migrate to "0008_alter_profile_profile_private" because "0009_remove_profile_user" was the migration that caused the issue to start with.

django_countries not being recognized for import in my Pycharm

I have successfully installed the package using pip install django-countries it comes up in my list of installed packages in my Django project. I added it to my list of installed apps in my settings.py - INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'ecommerce', 'accounts', 'cart', 'social_django', 'social_core', 'anymail', 'django_countries' ] So everything seems right, and at the top of my views.py, after all other imports I have - from django_countries import countries this is my views funtion that needs the import - def address_book_create(request): user = request.user # Get the logged-in user personal_details = user.personal_details # Add 'COUNTRIES' to the context dictionary context = { 'user': user, 'personal_details': personal_details, 'COUNTRIES': countries, # Include the country data } return render(request, 'accounts/address_book_create.html', context) So the line from django_countries import countries is being underlined in my Pycharm with the words "Unresolved reference 'django_countries'" I don't know why.the error is being shown because i …
