What are the primary advantages of using Django's built-in ORM (Object-Relational Mapping) compared to writing raw SQL queries in Django web development? Haven't tried anything yet, just asking question. Thanks in advance. -

UWSGI Why would there be unattended requests . According to the log
I've got the below in my uwsgi log running with Django and Nginx. The req: -/- field i believe is referring to the request count and the total number of requests respectively. They're both incrementing gradually but the gap is not being closed. I'm not sure what this means for my application as it looks like there're unattended requests that will never be attended. I've checked around but still didn't get the right answer to the situation. [pid: 305785|app: 0|req: 418/1873] 99.7.107.127 () {38 vars in 554 bytes} [Tue Nov 14 23:30:43 2023] GET /api/machines/endpoint/ => generated 385 bytes in 10 msecs (HTTP/1.1 200) 7 headers in 215 bytes (1 switches on core 0) [pid: 305785|app: 0|req: 419/1874] 99.7.107.127 () {38 vars in 562 bytes} [Tue Nov 14 23:30:43 2023] GET /api/machines/endpoint/ => generated 545 bytes in 40 msecs (HTTP/1.1 200) 7 headers in 215 bytes (1 switches on core 0) I'm expecting there'd be so little gap between the request count and the total number requests. I should also mention that this persists even after restarting the service itself. Perhaps some explanation on this behavior would clear my confusions . -
How to use the django-filer file selector in a rich text editor?
Django filer is a great remote image file resource manager. I want to modify all projects to django filer to manage server image resources, but I don't know how to choose to use the django filer file selector from a rich text editor? After consulting a lot of materials, I couldn't find a case where a rich text editor can perfectly integrate with django filer. Is it possible that the django filer file selector cannot be used in conjunction with a rich text editor? -

How to build a robust payment subscription pipeline? [closed]
I am building a subscription-based product in Django. The payment processor in this case is Razorpay. I have few doubts regarding the architecture that I have thought. Business Logic: The user subscribes to my platform and a subscription ID is created. I store it in my DB. Each month an automated job needs to adjust the subscription amount for all the subscribed users based on their usage because it's a usage- based model. Proposed Architecture: After researching a bit I wish to use Celery and RabbitMQ. I am already using RabbitMQ for a different service so planning to reuse it. So after the application is deployed, I start the celery worker. A couple of doubts that I have are, Can I add the command to start the Celery worker be a part of the deployment script? The deployment script spins up a bunch of docker containers for different services. Is this a good approach or is there a better way? My biggest concern is what if the job fails? Like what's the best error-handling strategy? I would appreciate any further suggestions on this architecture greatly. -

Queries too slow on PostegreSQL
I'm currently working on a project, using Django for web development and PostgreSQL as a database. I have noticed that queries on my system are starting to slow down as the amount of data increases. My main table, say Products, has millions of records, and simple queries like product listing are taking longer than I would like. I've already added some indexes to the relevant columns, but I still feel there's room for improvement. Here is my models: class Produto(models.Model): nome = models.CharField(max_length=255) descricao = models.TextField() preco = models.DecimalField(max_digits=10, decimal_places=2) estoque = models.IntegerField() class Pedido(models.Model): produtos = models.ManyToManyField(Produto) data_pedido = models.DateTimeField(auto_now_add=True) And this is the query I'm doing: produtos = Produto.objects.filter(estoque__gt=0).order_by('-preco')[:10] What am I doing wrong? How can I optimize this query? -

Django queryset.filter issue with model type pgfields.ArrayField(models.DateField())
I'm trying to filter a queryset by a date range, on the model it is pgfields.ArrayField(models.DateField()) it is stored in the actual table as text[] (ide). This is the specific piece of code that is failing triage_dates = [r.strftime('%Y-%m-%d') for r in list(rrule.rrule( rrule.DAILY, dtstart=parser.parse(range_start), until=parser.parse(range_end) ))] queryset = queryset.filter(triage_dates__overlap=triage_dates) when I print the type of each item in the triage dates list, it is str, I'm getting this error on the query django.db.utils.ProgrammingError: operator does not exist: text[] && date[]. HINT: No operator matches the given name and argument types. You might need to add explicit type casts. I've even tried converting each item to a date as well. I've been all over different AI platforms looking for answers. I'm thinking I might have to convert this over to a plainsql setup but would prefer to use the ORM if possible. I'm wondering if this is some weird bug between a postgres version + django or something. Any insight is welcomed, thank you! -
How to make delay tasks using Zappa with Django?
I am new to Zappa and I have usually used Django with celery in a server. I know that with Zappa I can schedule tasks with a rate, but how can I just execute a task delayed by a desired amount of time that does not have to be periodic? For example, give the user a finite time to buy a product, or to write a review, or to choose spots in a theater... I am also using AWS What I have read is to create a periodic event that executes every minute to check if the desired time have passed and then do the task, but I think that would be overkilling and I would prefer an event driven solution. I simply dont know if that is possible Another option was to create an SQS queue as this: "events": [ { "function": "your_module.process_messages", "event_source": { "arn": "arn:aws:sqs:us-east-1:12341234:your-queue-name-arn", "batch_size": 10, // Max: 10. Use 1 to trigger immediate processing "enabled": true // Default is false } } ] But I dont know how to put arguments, and just call one task I need without having one queue per function. Thanks and sorry if this is a fool question!!! -

Django base.html block overwriting

Say I have the following template <!DOCTYPE html> <html> <head> <title>My Project</title> {% block append_to_me %}{% endblock %} </head> <body> {% block content %}{% endblock content %} </body> </html> I would then use the following template for my views, my views render some wagtail components, and those components might want to use the append_to_me block.

Django Tables2 with TemplateColumn the View is not printing the request
I'm trying to print the request in my view but nothing happens when I click on the 'Editar' button (TemplateColumn), this is what I have in my code: tables.py import django_tables2 as tables from django_tables2 import TemplateColumn from .models import Vencimientos, LogAsistencia class VencimientosTable(tables.Table): asistencia = TemplateColumn( '<a class="btn btn btn-info btn-sm" href="{% url "checkin" record.id %}">Editar</a>') class Meta: model = Vencimientos template_name = "django_tables2/bootstrap5.html" fields = ("cliente","vencimiento","activo" ) attrs = {"class": "table table-hover table-sm"} urls.py urlpatterns = [ .... path('asistencia/<int:pk>/', CheckIn.as_view(), name='checkin') ] views.py class CheckIn(View): def get(self, request): print(request) return redirect ('asistencia') when I click on the "Editar" button in the table the idea is to get the record.id so I can add some extra code, but the button doesn´t do anything UPDATE I inspect the button and I see the link correct: The button doesn´t do anything still -
Django ORM ForeignKey queryset output using annotations
I have the following 3 django models (using some abstractions): class Person(models.Model): full_name = models.CharField(max_length=120, validators=[MinLengthValidator(2)]) birth_date = models.DateField(default='1900-01-01') nationality = models.CharField(max_length=50, default='Unknown') class Meta: abstract = True class Director(Person): years_of_experience = models.SmallIntegerField(validators=[MinValueValidator(0)], default=0) objects = DirectorManager() class Actor(Person): is_awarded = models.BooleanField(default=False) last_updated = models.DateTimeField(auto_now=True) class Movie(models.Model): MOVIE_GENRES = ( ('Action', 'Action'), ('Comedy', 'Comedy'), ('Drama', 'Drama'), ('Other', 'Other') ) title = models.CharField(max_length=150, validators=[MinLengthValidator(5)]) genre = models.CharField(max_length=6, choices=MOVIE_GENRES, default='Other') rating = models.DecimalField(max_digits=3, decimal_places=1, validators=[MinValueValidator(0.0), MaxValueValidator(10.0)], default=0) director = models.ForeignKey(Director, on_delete=models.CASCADE) starring_actor = models.ForeignKey(Actor, on_delete=models.SET_NULL, blank=True, null=True) actors = models.ManyToManyField(Actor, related_name="actors") As you can see in the code above, I have also 1 manager. Here it is: class DirectorManager(models.Manager): def get_directors_by_movies_count(self): return self.all().values("full_name").annotate(movies_num=Count("movie__director")).order_by("-movies_num", "full_name") And here is my problem. I need and output like this: <QuerySet [<Director: Francis Ford Coppola>, <Director: Akira Kurosawa>...> instead, I am receiving this: <QuerySet [{'full_name': 'Francis Ford Coppola', 'movies_num': 2}, {'full_name': 'Akira Kurosawa', 'movies_num': 1}...]> So, I need just one record: Director, not these 2 full_name and movies_num, but i want to preserve the same group and order logic. How to do this?
