1 min delay in Vue.js rendering
So i have an application which has django as backend and vue.js on the frontend. This app intereacts with a source with websocket connection and this source continuosuly sends values to the application. whenever these values exceed any nominal state, those exceeded values are added in the symtomslist and the main page displays the updated values instantly, as the watch function of the page is set to watch on symptomslist. So the problem i have is, when we logged in and started the simulation, the app has been rendering the new values instantly when the values were changed, but after somrtime, even if the values were changed, the page has been rendering them after 1 min(even though different people logged in at different times, the lag in rendering started to all of us at the same time). we timed it multiple times and it measured 1 min each time. but when we logout and log back in, the state is again being rendered instantly. can you tell what might be causing this issue The console is logged every second. Maybe this is the issue? -
Pagination within Django - combining two projects
I am working off of two different projects. I have the Example By 5 and a YT series that I previously used to get started with Django. I liked the Pagination from the yt series so I decided to use that method, however in the Example By process, we moved from the Class base view to a function and now the pagination does not show up. I have added what I thought was needed in the view and html page but still getting nothing. VIEW code: def post_list(request, tag_slug=None): post_list = Post.published.all() tag = None if tag_slug: tag = get_object_or_404(Tag, slug=tag_slug) post_list = post_list.filter(tags__in=[tag]) paginator = Paginator(post_list, 3) # 3 posts in each page page_number = request.GET.get('page') # Get the page number page_obj = paginator.get_page(page_number) context = {'page_obj': page_obj,'is_paginated': page_obj.has_other_pages()} # Check if pagination is needed try: posts = paginator.page(page_number) except PageNotAnInteger: posts = paginator.page(1) except EmptyPage: posts = paginator.page(paginator.num_pages) return render(request, 'blog/post/list.html', {'posts': posts, 'context' : context, 'tag': tag}) Here is the Pagination section of the html: {% if is_paginated %} {% if page_obj.has_previous %} <a class="btn btn-outline-info mb-4" href="?page=1">First</a> <a class="btn btn-outline-info mb-4" href="?page={{ page_obj.previous_page_number }}">Previous</a> {% endif %} {% for num in page_obj.paginator.page_range %} {% if page_obj.number … -
Best Approach for Text Chunking in AI Chat Agent using React and Django (Langchain) without Sockets?
I’m currently building an AI chat agent that needs to handle text chunking and display responses word by word in real-time. My setup involves a React (frontend) and Django Langchain (backend) integration. I want to achieve this without relying on sockets to stream data and instead use an approach that can fetch and display responses as they are generated, ensuring the user sees a continuous flow of words. Here's a breakdown of my current setup: Frontend: React (with or without Redux) Backend: Django integrated with Langchain for handling the AI logic What I’m Looking For: Text chunking: Best practices for chunking AI responses (word by word or partial sentences) and updating the UI in React. Real-time updates: How to fetch and display this data incrementally (e.g., fetching a stream or chunks) without using sockets. Efficient handling: Strategies for making the experience smooth for users, especially on the frontend with React. I prefer not to use WebSockets and want to stick with traditional HTTP requests if possible. Looking for an approach that handles data/response chunking seamlessly so users get real-time updates without long waits. If anyone has experience with Langchain in this context or can share ideas on how to achieve … -

Django `squashmigrations` leaving lots of RemoveField
I am trying to use Django manage.py squashmigrations to reduce the number of migration files and migration operations, after years of accumulation. Django should supposedly optimize the migrations and it does so to some extent. Other cases, that should be obvious optimization are missed though, for example below where a simple AddField+RemoveField field is not. Only the AddField gets inlined into the CreateModel, but then the RemoveField still remains, instead of completely leaving out the field from CreateModel. Ideally, there shouldn't be a single RemoveField left after a squash, if I'm not mistaken. Migration 1: Add the model class Migration(migrations.Migration): dependencies = [("data", "0104")] operations = [ migrations.CreateModel( name="MyModel", fields=[... ] ) ] Migration 2: Add a field to the model class Migration(migrations.Migration): dependencies = [("data", "0107")] operations = [ migrations.AddField( model_name="mymodel", name="process_name", field=models.CharField(default=None, max_length=300, null=True), ), ] Migration 3: Remove the same field from the model class Migration(migrations.Migration): dependencies = [("data", "0121")] operations = [migrations.RemoveField(model_name="mymodel", name="process_name")] Resulting squashed migration: class Migration(migrations.Migration): replaces = [...] initial = True operations = [ migrations.CreateModel( name="MyModel", fields=[ ( "process_name", # Should be possible to leave out ??? models.CharField(default=None, max_length=300, null=True), ), ], ), migrations.RemoveField(model_name="mymodel", name="process_name"), # ??? ] Is this expected or what … -
Issue Displaying All Colors of a Product Variant in Django Template
I'm working on a Django application where I have a Product model with a many-to-many relationship with a Color model. I want to display all colors associated with a product variant on its detail page. However, when I click on a specific color (e.g., white), the page only shows that color instead of all available colors for the product variant.

Django: Unable to display colors of linked products
I'm having trouble displaying the colors of linked products in my Django template. I have a Product model with a many-to-many relationship with a Color model, and I want to display the colors of the linked products.

Where do I put Django Debug Terminal in middleware
Django Debug Terminal's documentation says The order of MIDDLEWARE is important. You should include the Debug Toolbar middleware as early as possible in the list. However, it must come after any other middleware that encodes the response’s content, such as GZipMiddleware. But this can be a bit tricky. For example, in my settings.py I have MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ] In this situation is the best place to put debug_toolbar.middleware.DebugToolbarMiddleware right after django.middleware.common.CommonMiddleware since that uses force_text while AuthenticationMiddleware, SessionMiddleware and MessageMiddleware don't seem to encode anything? -
Why does Django Rest Framework Pagination work with Django.http JsonResonse() and not rest_framework.response Response()
I've followed the tutorial on enabling/creating custom pagination for ModelViewSets in Django Rest Framework (DRF). But the custom pagination doesn't show up as part of the content of the response. I only get my results split according to the 'PAGE_SIZE' setting in an object labeled data with no count, or page_size as defined in my custom pagination class.

Adding inlines to existing User model changes User admin pages
I have Domain model with a many-to-many user field to the existing User model. I want a Domain select field when I Add or Change a User on these User Admin pages. I used admin.TabularInline to achive this. The attached images show how changed the Add page after add inlines to the code. The minimal fieldset extended to a full fieldset what Django uses when someone edits an existing user, and the fieldsets completely mixed compared to the original page without inlines. Original Add User page The changed Add User page This is the actual code I tried, and the image above shows the working inlines with the Domain field, but I don't want to change the rest of the page. I'm satisfied with the existing Django User model and templates, I don't want a Custom User model and templates either, if I can avoid that. # model.py from django.db import models from django.contrib.auth.models import User from django.utils.translation import gettext as _ class Domain(models.Model): domain = models.CharField(_('Domain name'), max_length=100) master_dns_server = models.CharField(_('Master DNS server'), max_length=100, blank=True, default='') updatekey_secret = models.CharField(_('Key'), max_length=255, blank=True, default='') updatekey_name = models.CharField(_('Key name'), max_length=50, blank=True, default='') updatekey_algorythm = models.CharField(_('Key algorythm'), max_length=50, blank=True, default='') last_transfer = models.DateTimeField(_('Last … -
how can I save and continue if WebDriverWait did not find the class
I want that if WebDriverWait didn’t find what it was looking for, continue the cycle and save it in the database, I tried giving the src_iframe variable and checking if not src_iframe but it didn’t help ` try: drivers.get(film_url) iframe = WebDriverWait(drivers, 8).until( ec.presence_of_element_located((By.ID, "cinemaplayer-iframe")) ) src_iframe = WebDriverWait(drivers, 8).until( lambda d: iframe.get_attribute('src') != '' ) if not src_iframe: film_instance.is_completed2 = True film_instance.save() continue ` -
Large file download fails on slow network using HTTP/2 and AWS ALB
Given the following architecture: client <-> AWS ALB <-> uwsgi <-> Django The client fails to download a 12MB file when using HTTP/2 (the default), but works using HTTP/1.1. The file is streamed through Django for authentication purposes (it's fetched from a third party service). Here is an example of failure (I'm using a Socks proxy to limit bandwidth): $ curl -x socks5://localhost:1080 https://example.com/file.pdf --output "file.pdf" % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 79 12.6M 79 10.0M 0 0 61254 0 0:03:36 0:02:51 0:00:45 64422 curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1) However the same command with the flag --http1.1 works fine. This fails when I limit downloads to 512kbps - it works at 1024Kbps. I've not looked for the sweet spot, it's not important. Notes: This also fails with a browser, it's not a curl issue Using curl with -v doesn't give any additional information. uwsgi does not output any errors. As far as it's concerned it did it's job. This is the output: [pid: 44|app: 0|req: 2603/9176] [ip] () {34 vars in 639 bytes} [Wed Oct 16 09:29:29 2024] GET /file.pdf => …
