Best practices of implementing a computationally intensive task on a socket connection [closed]
The context is as follows: I am working on a specific widget on the dashboard of a SAAS product. The backend is in Django. The widget displays a line graph of certain measurements updated real time. This part is implemented using Django channels. Among the various buttons at the bottom of the widget is one that initiates a time consuming calculation, the result of which is another line graph overlaid on the same figure. Note: The dashboard has other widgets on their own socket connections. So unless I am mistaken this seems to be both a CPU bound as well as an IO bound problem. Initially I had decided to use celery to offload the calculation on a different process but after a bit of research it seems that one normally uses celery for fire-and-forget tasks where the end result of the process doesn't have to be returned to the user which doesn't fit my use-case since I have to feed the result of my computation back to the user. In my research I have also found a few libraries that may help but I am unclear about whether they are the way to go or too much for my … -
Saving formset related models by multi-room relationships in Django
Please tell me how to save a formset with two models related to the manytomanyfield relationship, it turns out while two forms are displayed when the page is opened, after filling in and clicking on the "Add" button, the "phone" and "client_name" fields are cleared and the form is not sent. In view class OrderCreateView(CreateView), checking client_formset.is_valid() returns False.

Investigating Slow Performance in Adding Products to Django Oscar Basket via REST API
I'm currently facing performance issues when adding products to the shopping cart in a Django Oscar-based e-commerce application. The problem becomes particularly noticeable when the basket contains around 50 items. I'm using Django Oscar's REST API for adding products to the basket, which is called by JavaScript. The challenge is to identify the root cause of the slowdown and explore possible solutions. Observations: Adding products through product list views is slow. Adding products through the product detail page remains fast even with a considerable number of products in the cart. Details: API Endpoint: http://localhost:8000/en/api/basket/add-product/ Direct Adding via Detail Page: http://localhost:8000/en/basket/add/12787/ Offer Calculations: Offers are a significant concern, as adding a line to the basket triggers the calculation of all available offer conditions for each row. Investigation So Far: Middleware Approach: For direct adding via the detail page, offer calculations are handled in Django Oscar's BasketMiddleware during the redirect page load. This code might be better optimized compared to the custom code in the API. Offer Calculation in API: The problem intensifies when the basket consists of 30+ basket lines with different products. The query count increases linearly with the basket line count during API calls. Request for Help: I'm seeking … -
CreateView template not found
I am trying to create a CreateView in Django, but am facing a 'template not found' error (shown below) Currently, I have the following code: views.py: from django.shortcuts import render from django.views.generic import ( ListView, DetailView, CreateView, DeleteView ) from .models import EventPost class EventPostListView(ListView): model = EventPost template_name = "event_blog/home.html" context_object_name = "event_posts" ordering = ['-date_posted'] class EventPostDetailView(DetailView): model = EventPost class EventPostCreateView(CreateView): model = EventPost fields = ['name', 'location', 'locked', 'description', 'image'] urls.py: from django.urls import path from .views import * urlpatterns = [ path("", EventPostListView.as_view(), name="event-blog-home"), path("event/<int:pk>/", EventPostDetailView.as_view(), name="post-detail"), path("event/new/", EventPostCreateView.as_view(), name="post-create"), ] You can see I have already used a ListView and DetailView which has worked fine. The code from these views also extends 'event_blog/base.html' so I do not expect this to be the issue.

Django Rest - Redirect Password Form?
I recently upgraded to Django 4.0 and upgraded django-allauth with alongside django-rest-auth.

Django app cannot delete AWS S3 bucket items
DISCLAIMER: (I'll put it at the top so people don't just skip and not read) I just recently started using AWS so I still don't understand a lot of things and yes, I already did the research on this subject and every post I found said to "make the bucket publicly available" which is something I would like to avoid and that should not be the correct answer since, in the tutorial I was following, the guy used it as private blocking all outside access. The upload of an Images works without issues, so I would roule out any problem with the connection itself, but when I try to delete one I get the error An error occurred (AccessDenied) when calling the DeleteObject operation: Access Denied I was following a tutorial about how to connect the bucket to django. The steps I took: Created a bucket (not public like it said in the tutorial) Created a User Group with "AmazonS3FullAccess" policy Created a User inside the group with both the S3 full access and the "AWSCompromisedKeyQuarantineV2" policy Generated the necessary keys (secret and access) The S3FullAccess policy should be this one: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": … -
Django Model Inheritance: Every
In Django, I want to have several models of the same type: ANode, BNode, CNode are all of type "Node". In the database, you can look up a "Node" by id, then quickly get what kind of Node it is (ANode, BNode, CNode), and then reference that node. Every node is only of one specific node type, and there are node "Nodes", only "ANodes", "BNodes", "CNodes". There may be many kinds of Nodes (A-Z) each with different fields. I can picture the underlying SQL: there is a "Node" table with an ID column and an enum field keeping track of which type of Node it is. How can I implement that? -
How to let Django serve images when hosting on Vercel
I deployed a Django project on Vercel. The app is responsible for serving data to a Next.js frontend. However, the images don't get served while other data do. GET request to the images return NOT FOUND error after deploying to Vercel. I have studied all similar questions on this platform but none seems to solve my problem. I have this in my settings.py file: STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles_build', 'static') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/article_photos') I'm serving only the article_photos. I have this in my project urls.py file: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) This is the structure of my media folder: I have struggled with this problem throughout the whole day.

Python Django and parallel process
I'm making a delayed messaging service in Django. I reached the task manager. In theory, it should be launched in parallel with Django, its task is to “read the database” and send messages. I used "multiprocessing Pool", the code was entered into manage.py. It confuses me that when starting, one of the processes fires twice, “ok” in the screenshot. Using a parallel process, the site is assembled and works properly. why is that? Are there any better practices? Result: не ok не ok Performing system checks...

Make dynamic imports of ts module absolute path in js using Webpack
I'm using Webpack as a bundler. My project contains .ts files with dynamic imports. And everything works just fine. But It is Django project and compressor doesn't see modules to which path is build dynamically. Is there a way to make webpack not build path to module but put it as full string in .js file? This is how it looks now: const obj = await import('../components/MyComponent/MyComponent'); In bundled js: const e = await r.e(3802).then(r.bind(r, 73802)); It is building a path to this module. And I would like to have it as an absolute path. Is there a way to do so? -

Django tables2: Table reverts to previous value

I have the following field defined on my model: email_body = RichTextField( verbose_name=_("Email Body"), help_text=_("Body of the email to send when you are out of office."), features=[ "bold", "italic", "ol", "ul", "hr", "h2", "h3", "h4", "h5", "h6", "code", "superscript", "subscript", ], max_length=2048, blank=True, null=True, ) However; when including links, images or documents in the features; the urls generated are all relative: <p data-block-key="e0dv1"><a href="/documents/14/Kunststof_Catalogus_F1204.pdf">Kunststof Catalogus (F1204)</a></p> <img alt="" class="richtext-image right" height="498" src="/media/images/aluminium-catalogus-f2204-page4_1.width-500.jpg" width="500"> <p data-block-key="5nssj"><a href="/nl/producten/">Producten</a></p> <p data-block-key="aa12u">Het <a href="/nl/"><b><i>(REDACTED)</i></b></a> team, 2023</p> As implied by the field name; this is used in emails; thus I cannot use relative URLs. The HTML is generated like so: (It is designed for template injection. Only to be used by admins.) template = util.template_from("from_string", self.email_body) body = richtext(template.render(context, request=request)) context["body"] = body context["email_body"] = body is_file = True as_html = True template_name = "office/emails/closed_email.html" How can I make the richtext editor always generate full (absolute) URLs? -

Change Model data after form submission in Django
Im writing a Booking System in Django with ModelForms, I Want to change value of a Boolean field in a ForeginKey model when form saves. models.py class AvailableHours(models.Model): free_date = models.ForeignKey(AvailableDates, null=True, blank=True,on_delete=models.CASCADE) free_hours_from = models.CharField(max_length=10,null=True, blank=True) free_hours_to = models.CharField(max_length=10,null=True, blank=True) status = models.BooleanField(null=True,default=True) class Bookings(models.Model): ... booked_time = models.ForeignKey(AvailableHours, on_delete=models.CASCADE,related_name='booked_time') views.py @login_required() def booking_form(request): form = forms.BookingForm() if request.method == 'POST': form = forms.BookingForm(request.POST) if form.is_valid(): book = form.save(commit=False) book.user = request.user form.save() return HttpResponseRedirect(reverse('creator:login')) return render(request, 'account/book.html', {'form': form}) forms.py class BookingForm(forms.ModelForm): class Meta: model = Bookings exclude = ('user','booking_code','confirmed',) Since I want each AvailableHours be able to get booked only once , I need the form to change value of AvailableHours status to False so I can filter it in templates. Can anyone suggest an approach to this issue ? I Tried something like form.booked_time.status = False in my views but it didnt work -
