How to make Django pagination with ajax without re-querying the DB
I've checked many related questions on building up pagination with ajax and implemented it in my app. The problem I still have is querying DB each time user сlicks next or prev because ajax call goes to the view function. My code: my_template.html <ul class="list-articles" id="dd"> </ul> <div class="buttons"> {% if page_obj.has_previous %} <a href="#" onclick="ajax_function('{{page_obj.previous_page_number}}','{{title}}')" id="prev">&#10094; prev</a> {% endif %} {% if page_obj.has_next %} <a href="#" onclick="ajax_function({{page_obj.next_page_number}},'{{title}}')" id="next"> next &#10095;</a> {% endif %} </div> views.py def my_view_function(request): if is_ajax(request=request): if 'page' in request.GET: return paginate(request) def paginate(request): parameter_a = request.GET['parameterA'] parameter_b = request.GET['parameterB'] li = MyModel.objects.filter(par_a=parameter_a, par_b=parameter_b) paginator = Paginator(li, 1) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) context = { 'page_obj': page_obj, ... } return render(request, f'my_app/my_template.html', context) main.js function ajax_function(page, title) { $.ajax({ url: '', type: "get", data: { 'page': page, 'title':title, }, success: function(response, status) { $('#dd').empty(); $('#dd').html(response); } }); } So this code is working but in real app I have more complex db queries to get my Model's objects, so every next/prev iteration will recall the objects again and again which look dump. Ideally I'd like to collect the list of objects once and then use them without any additional queries. I'm not a JS … -

Heroku app won't restart after error 14 (Memory quota exceeded)
We have a Django app deployed on Heroku with the following Procfile: release: python manage.py migrate web: gunicorn RDHQ.wsgi:application --log-file - --log-level debug celery: celery -A RDHQ worker -l info Yesterday the app was down and accessing the site returned ERR_CONNECTION_TIMED_OUT. When I looked at the logs, I saw that the celery process was showing an R14 (Memory usage exceeded) error: 2022-12-24T07:14:46.771299+00:00 heroku[celery.1]: Process running mem=526M(102.7%) 2022-12-24T07:14:46.772983+00:00 heroku[celery.1]: Error R14 (Memory quota exceeded) I restarted the dynos a couple of times, but the celery dyno immediately throws the same error after restart. I then removed the celery process entirely from my Procfile: release: python manage.py migrate web: gunicorn RDHQ.wsgi:application --log-file - --log-level debug After I pushed the new Procfile to Heroku, the app is still down!

Display related foreign keys in the parent model in Django admin
I'm using PostgreSQL for the DB. I have two models: Project: can contain N Assets. Asset: has a Foreign Key field that points to a Project. An Asset is related to 1 Project. I want the user to be able to set the order of the Assets of a Project in the Django Admin in a handy way like ordering a list in the edit Project screen. The order of the Assets is important in my bussiness logic, but I dont want the user to set the order in each individual Asset (just to improve UX). Is there a way to show a field in the Project admin screen that lists all the Assets that are related to the project and allow the user to order it as he wishes? I did not found any solution to this more than adding a new field in the Asset modal to specify the order and handling the logic by myself (which is expected), however, I don't want it to be a field that have to be changed manually in each individual Asset. -

What is the right redirection?
I'm a beginner in Django and I want to display the username from the nav bar. I did not use User athentication. I only created custom database table called JobseekerJobseeker database table. Because the criteria is the user should be able to login using username or email then password. I was able to achieve that using this code,code for username/email login. Now my problem is using {{request.user}} in the nav bar it display the superuser's username, instead on the jobseeker username. Superuser's username. Code for the HTML I want to display the username that i inputed in the login form. It should be one of these username that needs to be displayed sorry for the bad english but hopefully it makes sense. -
How to get rid of not existing errors?

Code works fine and it doesn't displaying any errors while server is running and request is sent. But it is underlined in red, so something must be wrong. How can i get rid of those "errors"?

How to handle IntegrityError exception of conditional unique constraint in Django/Postgres?
let's assume we have the below model class code: from django.db import models class SupplierAddress(models.Model): """Model to create supplier's address instances""" class Meta: """Customize django default way to plural the class name""" verbose_name = 'Supplier Address' verbose_name_plural = 'Supplier Addresses' constraints = [ models.UniqueConstraint( fields=['supplier', 'address'], name='supplier_address_unique_appversion' ), models.UniqueConstraint( fields=['supplier'], condition=models.Q(is_default=True), name='one_default_address_per_supplier' ) ] # Define model fields. supplier = models.ForeignKey( 'Supplier', on_delete=models.CASCADE, related_name='supplier_addresses_supplier' ) address = models.ForeignKey( 'Address', on_delete=models.CASCADE, related_name='supplier_addresses_address' ) is_default = models.BooleanField(default=False) def __str__(self): """String representation of model objects""" return '{}, {}'.format(self.supplier, self.address) This model constraints will make sure there is unique constraint between supplier and address foreign keys AND a conditional unique constraint between supplier and is_default when it's True. The conditional unique constraint in Django and Postgres as database engine, will raise an exception: IntegrityError: duplicate key value violates unique constraint... In case the input by user go against the constraint condition. Ideas to handle such case: 1- handle such case on user side, like using forms But not a good idea for testing. 2- using clean() method and raise an error message, like: def clean(self, *args, **kwargs): """Restrict the add/change to model fields""" if self.is_default is True: if SupplierAddress.objects.filter( supplier=self.supplier, is_default=True ).exclude(id=self.id).count() >= 1: … -

multiple instances of django using 1 celery
I'm using Django as webserver, and redis as broker. I have 3 virtual machines running the same Django app and load balance among them and 1 redis server shared between them. Problem we are facing now is that if we run workers and scheduler on each machine then if we run task_1 on machine 1 then all machines run it 1 time.(total of 3 times.) if we turn off the worker and scheduler on 2 of the machines ( let's say 2 , 3). and then run task_1 on machine 1 everything is okay. but if we run it on machine 2 or 3 nothing happens. my plan is to change celery broker url on each machine and change database so instead of redis://host:port on all of them it would be redis://host:port/1 redis://host:port/2 redis://host:port/3 I wanted to know if this is the right way to go or is there another general solution which only requires 1 machine with celery running on it? -
Updating templates in django app without re-rendering the pages
I'm making a Django web application in python, similar to language learning quiz. It consists of three different parts. One is showing the set of sentences to a user (one element per page) and the second is asking questions about sentences that was just shown. The third one is showing results and asking for redo the wrong q/a. Each part has next/prev buttons for iteration and the content of the sentence. I also need to store info to DB when the user answers the question right to not to show it again. The set of questions is provided by a view function through filtering the models objects. I need to have these 3 stages without page rendering. I face the following problem: The list of questions is passed to the template to iterate over it once to present sentences, then I need to start the loop again with the only difference of adding a field of textarea for answer and a few buttons. What is the best way to do it? I was thinking about some ajax function that'll be triggered after the first loop is finished. This js function can refill the certain tags with textarea and buttons.

Using Django Rest Framework, how can I capture values from an URL to a viewset using routers, not with URLconf?
I have two models: the first is named Card and has a foreign key (named owner) to the second model (User). I'm trying to write a view that lists all the Cards owned by a User, the client selects the User by changing the URL (not query parameters). For example, if I make a GET request to /cards/by-user-id/42/, I should get all the Cards owned by the User whose id is 42. From what I understood, it is possible to achieve this by using an URL pattern like this : path('cards/by-user-id/<int:user_id>', my_view.as_view()) and then in the viewset I can use self.kwargs['user_id'] to get the id and then filter the data. However, I can't find how to do it using routers (more appropriated for djangorestframework). I tried with <int:user_id> in the prefix but it does not pick it up, it just considers it as a normal string, so not only the URL is incorrect (I have to type literally /cards/by-user-id/<int:user_id>/) but also kwargs doesn't contain 'user_id'. Here is what I tried: models.py: from django.contrib.auth.models import User from django.db import models class Card(models.Model): owner = models.ForeignKey(User, null=True, on_delete=models.SET_NULL) serializers.py: from rest_framework import serializers from . import models class CardSerializer(serializers.ModelSerializer): owner = serializers.StringRelatedField() … -

Django Login/Logout Logger
I have a django project where I need to know how much time each user spends on the site. The first thing that came to my mind was that since I have a CustomUser I can create my own login/logout view and populate a table with login and logout and the user's identifier.
