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? -
images Not Loading in xhtml2pdf with medial_url, Any Solutions? django
I'm encountering a peculiar issue in my Django project involving xhtml2pdf.

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!!! -
How can I avoid re-triggering a django signal?

Django base.html block overwriting
I want to define, and append to blocks defined in the base.html template. 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. This goes not only for the wagtail blocks, but also for plain django template tags {% extends "base.html" %} {% block content %} <h2>Content for My App</h2> <p>Stuff etc etc.</p> {# I want it to not matter where I use this. #} {% my_custom_tag %} {% endblock content %} Where {% my_custom_tag %} would do something like this: @register.simple_tag(takes_context=True) def my_custom_tag(context): objects = Preload.objects.all() for object in objects: append_to_header_block(object.html) Wagtail block example: class MyBlock(blocks.StructBlock): title = blocks.CharBlock() content = blocks.RichTextBlock() class Meta: template = 'myapp/myblock.html' myapp/myblock.html {% add_to_header IMG "img/my-img.jpeg" %} ... I also want to be able to keep the content of previous calls to the add_to_header function, as to not overwrite the previous content.

How can properly verify a user is 18 or older in django?
I want to validate whether a user's age (birth_date) is 18+, this is my current code though it isn't working: ... def min_date(): return (date.today() - timedelta(days=6570)) class User(BaseModel, RemovabledModel, AbstractUser): birth_date = models.DateField( verbose_name=_('birth date'), help_text=_('Birth date'), null=True, blank=True, validators=[ MinValueValidator( limit_value=min_date(), message=("User must be 18 or older") ), ] ) This runs and is functional, but I can still set a user's age to today's date without the application throwing any error message like it would with other validators. Edit: In case it is relevant, this is related validator: def min_date(): return (date.today() - timedelta(days=6570)) class SignUpSerializer(serializers.Serializer): birth_date = serializers.DateField( write_only=True, required=True, validators=[ MinValueValidator( limit_value=min_date(), message=("User must be 18 or older") ), ] ) -

How to generate a user-specific PDF in Django based on user ID?
I'm ivan, a junior-level Computer Science student and aspiring developer. I'm currently delving into web development using Django. As part of my learning journey, I'm working on a project where I need to generate a customized PDF for each user, identified by their unique user ID. My current experience is at the junior trainer level, and while I'm familiar with the basics of Django, I'm struggling a bit with the specific implementation of PDF generation using a particular library. I would like to seek the community's assistance in understanding how the [library name] library works in Django and how I can apply it to create these user-specific PDFs based on user ID.
