Django HTML to pdf not displaying when for loop longer than 1 page
Note: The html renders to pdf perfectly when the objected passed to the pdf function does not exceed the size of one page. Funnily enough when i remove the styling from the html it works, and by works i mean renders to pdf and create multiple pages... but now obviously without styling!

Django Models : array of fields
I need a form with 'hundreds' of integer input fields. I was thinking to create an array of integer fields in my model, but this doesn't seem to function: class Array(models.Model): name=models.CharField(max_length=10) data=[] for i in range(100): data.append(models.IntegerField(default=0,blank=True)) Via de shell I can create a record, change a data field and store... from app1.models import Array a=Array(name='first') a.data[0]=10 a.save() but retrieving later doesn't function: I get only <django.db.models.fields.IntegerField> but no actual values... I know about the ArrayField in postgres, but I just use SQLite... Any smarter way than creating 100 individual IntegerFields? -
Django DRF bulk_update primary key
I have used the example from the docs for implementing bulk update: class BookListSerializer(serializers.ListSerializer): def update(self, instance, validated_data): # Maps for id->instance and id->data item. book_mapping = {book.id: book for book in instance} data_mapping = {item['id']: item for item in validated_data} # Perform creations and updates. ret = [] for book_id, data in data_mapping.items(): book = book_mapping.get(book_id, None) if book is None: ret.append(self.child.create(data)) else: ret.append(self.child.update(book, data)) # Perform deletions. for book_id, book in book_mapping.items(): if book_id not in data_mapping: book.delete() return ret class BookSerializer(serializers.Serializer): # We need to identify elements in the list using their primary key, # so use a writable field here, rather than the default which would be read-only. id = serializers.IntegerField() ... class Meta: list_serializer_class = BookListSerializer https://www.django-rest-framework.org/api-guide/serializers/#listserializer When I try to use this and update a row, I get an error: duplicate key value violates unique constraint \"api_book_pkey\"\nDETAIL: Key (id)=(7) already exists.\n" So it seems like it is not trying to update, rather than creating a new one with the same id. But for me it looks like it is really calling child.update. What is wrong here? -
How to serve media files with control traffic?

Working with multiprocessing and Celery tasks
I'm working on a web scraping project in Django. The goal is to scrape advertisement data from 3 websites, create each advertisement as model object, and list them in a view. I've got four scraping functions, for which I've used multiprocessing module in order to run all of them at the same time. All of these functions are ran in this function: @shared_task def run(): ad_list = [] running_tasks = [Process(target=task, args=[ad_list]) for task in [scrape_lento_flats, scrape_lento_houses, scrape_morizon, scrape_gethome]] for running_task in running_tasks: running_task.start() for running_task in running_tasks: running_task.join() return save(ad_list) and then the result is saved: @shared_task(serializer='json') def save(ad_list): for ad in ad_list: location = Location.save( name = ad['location'] ) type = OfferType.save( id = OfferType.types[0] if ad['type'] == 'for sale' else OfferType.types[1] ) category = Category.save( name = ad['type'] ) Advertisement.objects.create( title = ad['title'], description = ad['description'], price = ad['price'], source = ad['source'], url = ad['source_url'], location = location, type = type, category = category, photo_url = ad['photo_url'] ) All of these functions exist in tasks.py file, annotated with Celery's shared_task (except for two util ones, which are simply "polishing" scraped data).
