IntegrityError - NOT NULL constraint failed in the `models.DecimalField`
I'm trying to build a models.DecimalField which will set to 50 and will have a range (from 50 to 9000) with a step 50. I have read that I can use choices: "A sequence consisting itself of iterables of exactly two items (e.g. [(A, B), (A, B) ...]) to use as choices for this field. If choices are given, they’re enforced by model validation and the default form widget will be a select box with these choices instead of the standard text field.". I have no idea how to fix it. For sure error is in quantity = models.DecimalField. My code: from django.db import models # Create your models here. class ProductInquirie(models.Model): email = models.CharField(null=False, blank=False, max_length=120) # max_lenght required tittle = models.TextField(null=False, blank=False) quantity = models.DecimalField( null=True, blank=True, decimal_places=0, max_digits=4, default=50, choices=[(i, i) for i in range(50, 9000, 50)] ) target_price = models.DecimalField(null=False, blank=True, decimal_places=2, max_digits=7) # Why decimal not float: https://docs.python.org/3/library/decimal.html#module-decimal one_time = models.TextField(default="client didn't provide information, or want constant supply") constant_need = models.TextField(default="no information") how_soon = models.TextField(default="no information") Error: Expected behaviour: It should look like this: Unfold, like this: ...but, without errors when saved(till now the error appears when the "save" button is pressed):) -
How to update a foreign key's attribute after creation of object in Django Model
I'm creating a REST API using Django that has two models that relate to each other: Item and Attribute. An Item has Attribute as a foreign key. The Attribute model has a field called number_of_uses which stores the number of items that attribute has associated it with. I wanted to know how I can update that number on the creation of a new Item. How can I update the field after the creation of the item, but before the API returns a response to the caller? -

TemplateDoesNotExist at / index.html (Django)
I'm currently trying to get my full stack app (React and Django 4.0) to deploy on Heroku, but when I load the landing page, I get a TemplateDoesNotExist at / index.html error on the page. Like so: However, I can get the django admin page to load just fine.

Djanog limit image upload size

How to filter my model objects based on Tree QuerySet from MPTT Django?
I was fighting with creating a categories with parent categories. Similar to this: - Category 1 - SubCategory 1.1 - SubCategory 1.2 - Category 2 I managed to do this with django-mptt and MPTTModel and TreeForeignKey: class Category(MPTTModel): title = models.CharField(max_length=100) parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children') And I am happy with it, I am doing all the magic in templates and in views.py I am getting 'TreeQuerySet' object. And I can see that it is working (I used method get_family()), if I will send Category 1 then in this TreeQuerySet object I have (Category 1, SubCategory 1.1, SubCategory 1.2) so success.

And I was trying many things with union, for loops and other stuff, but it all failed most of the time because object TreeQuerySet doesn't have such and such method.

Real-time scraping website with Django: stoppable scraping process and loading bar
What I would like to achieve I would like to make a website that allows users to scrape information from other websites. My goal is to achieve something as follows: User presses "scrape" When the scraping process begins, Django renders a view with a loading message and a "stop" button If the user presses the "stop" button, or if the scraping process terminates, a view with the scraping results is shown Current state At the moment, I have a very simple scraping website with a horrible user experience. After the user presses scrape, I render a view similar to the following one: def scraping_view(request, scraper_args): scrape_results = scrape(scraper_args) # Very long function! return render(request, 'scrape_view.html', scrape_results ) This is a bad idea, as the scrape function takes a long time, and the user experience is terrible. My (probably bad) idea My idea was to: launch a celery task and render an intermediary view with the loading message and a "stop" button let the celery task store the scrape results somewhere (where?) find a way to revoke the task if the user presses the "stop" button retrieve the results of the celery task when the task is finished or when "stop" … -

Django Channels does not work inside a DjangoQ jobs or hooks handler
I am trying to trigger a websocket message when a DjangoQ job ends, but it doesn't work. The same code works inside a views.py APIView that queues the job, but does not work inside my jobs.py handler. It does not generate error. It does nothing. views.py # works (calls consumer handler, websocket event emitted and logged on browser console) from channels.layers import get_channel_layer from asgiref.sync import async_to_sync def event_trigger(): channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)( 'event_sync', { 'type': 'send_message_to_frontend', 'message': "event_trigered_from_views" } ) Same code called from hooks.py does not work. Does nothing. hooks.py from channels.layers import get_channel_layer from asgiref.sync import async_to_sync def event_trigger(): channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)( 'event_sync', { 'type': 'send_message_to_frontend', 'message': "event_trigered_from_hooks" } ) def import_wallet_completed(task): ic(task.result) event_trigger() Invite.objects.update_or_create( emoji_key=task.result['emoji_key'], defaults={ 'job_status': 'wallet_imported' } ) What could be going on?
