How to get limited results per page in django using pagination?
I am following a udemy course where I am making a real estate website using Django. I have come so far and have been fighting with the errors but I am stuck with the pagination error that I am facing right now. I see everything is working fine in the video but when I follow it exactly it does not work. The issue is that when I set a limit on items per page, it does not seem to be working as I see all the results on the same page. Here is my views.py from django.shortcuts import render from django.core.paginator import Paginator from .models import Listing def index(request): listings = Listing.objects.all().order_by('-id') paginator = Paginator(listings, 3) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) context = { 'listings': listings } return render(request, 'listings/listings.html', context) It's my Urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='listings'), path('<int:listings_id>', views.listing, name='listing'), path('search', views.search, name='search') As you can see, I have set maximum 3 listings per page but I am getting all of them on a single page which is not what I want. It would be great if anyone could help. Thanks for your time and efforts. -

Python Django - HTML for REST API JSON data in Async
I am making a Django web app. So far I have used templates for creating HTML in response to a POST request. I use 'context' to pass data to the template and fill the HTML with that data. This does not require any client-side work. Now I added a REST API to the app to be used Async, and I want all data to be processed by the API and return only in JSON format. This creates a problem, I cant use the templates anymore since I can't use 'context' to fill in the data in the HTML, I have to use client-side JS to do the filling but now I am missing the HTML appropriate to the data received.

What is the efficient way to resize/process image and upload to s3 in django?
I am fairly new to django. I was wondering what would be the best approach to process an image file and upload to s3. I could think of a couple of approaches but not sure which one to pick. They are as follows: 1) Upload raw unprocessed image directly to s3 from client(mobile app), resize/process it (using Celery) and then replace the original file with the processed one. 2) Send raw image to django, process it and then upload to s3. Thank you. -

Django alter admin save to alter another table field
I am creating a django site that includes a rudimentary inventory system. Which includes the following models class Stock(models.Model): # Fields location = models.ForeignKey(Location) product = models.ForeignKey(Product) quantity = models.IntegerField() class Transfer(models.Model): # Fields location1 = models.ForeignKey(Location, related_name='location1') location2 = models.ForeignKey(Location, related_name='location2') date_transferred = models.DateField(default=timezone.now) class TransferLine(models.Model): # Choice set direction_set = ( ('1TO2', 'From 1 to 2'), ('2TO1', 'From 2 to 1') ) # Fields transfer = models.ForeignKey(Transfer, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True) quantity = models.IntegerField() transfer_direction = models.CharField(max_length=4, choices=direction_set, default='1TO2') When I create a new transfer I want to be able to automatically deduct and add the product in the TransferLine from the quantities in the Stock model. I have figured out how to override the save_model method in the admin.py file for the TransferAdmin class, but I cannot figure out how to access the Stock model from within the SaleAdmin class. Is this something that can be done in the admin? Will I have to create my own form? I really wanted to do this from admin because inlinetabular is really easy to do within admin compared to within a custom built form. (At least from what I can find.) Any help on this would be … -

Django select related with max field value for each result

How to setup permissions to graphql relay queries in Django Graphql that uses JWT authentication
This is a recent problem I encountered in Django I setup a django backend server that serves a graphql api and I used Django Graphql JWT that offers auth functionnality the documentation is here the package offers decorators that can be setup with resolvers and it works perfectly with that, the issue occurs when I try to setup a relay query and would like to authorize that to logged users. Since the syntax to use relay in django excludes the use of a resolver method and therefore really don't know how to setup the authorization. Thanks in advance. -

Threads can only be started once in Django channels
I created a simple Django Channels consumer that should connects to an external source, retrieve data and send it to the client.

Django CMS Carousel
I am learning/developing my company website. and I really don't know how to add the correct plug-ins on this Carousel that I have and also integrate with all the translations. But static code bellow works fine, but I would like to convert that to the django-cms plugin format <header> <div class="container-fluid"> <div class="slider-container"> <div class="owl-slider owl-carousel"> <div class="item"> <div class="owl-slider-item"> <img src="{% static 'home/images/slide-1.png' %}" class="img-responsive" alt="portfolio"> <div class="intro-text"> <div class="intro-lead-in">Text1 Lead</div> <div class="intro-heading">Text1 Heading</div> </div> </div> </div> <div class="item"> <div class="owl-slider-item"> <img src="{% static 'home/images/slide-2.png' %}" class="img-responsive" alt="portfolio"> <div class="intro-text"> <div class="intro-lead-in">Text2 Lead</div> <div class="intro-heading">Text2 Heading</div> </div> </div> </div> <div class="item"> <div class="owl-slider-item"> <img src="{% static 'home/images/slide-3.png' %}" class="img-responsive" alt="portfolio"> <div class="intro-text"> <div class="intro-lead-in">Text3 Lead</div> <div class="intro-heading">Text3 Heading</div> </div> </div> </div> </div> </div> </div> </header>
