Should i have one django view that has lots of children or just lots of views
I have an api in django with a User class, this class has all CRUD operations and then I have children classes that inherit from this and on get or post requests they call x function e.g BaseUser(APIView): CRUD CreateUser(BaseUser): def post(self, request): BaseUser.create_user(request) then i have another for delete or get info etc but should these be this pattern where its one top user class and lots of children that inherit and call the CRUD operations or should these classes be broken out into their own thing e.g. one with all create logic then one with all delete logic for user. -

Google map integration for website through django
I'm using django(python) to code the page. is it possible to add a Google map feature, that specifically searches for nearby supermarkets based on user location? I see how changing the api adresss to change the search results in the Google document but in all the examples you need to have location as a latitude and longitude. can the webpage just prompt the user for location permissions and the code uses that location? I'm not exactly sure if I made the question clear but I will be grateful if anyone could point me in the right direction. -
What is the ideal way to store comments to a blog?
I am making a demo website using django and in the website you have blogs. What im trying to add is a way to add comments for every blog and what im trying to figure out is how to arrange the database. I thought about 3 options either you store with every blog a list of the comments or you store a list of all comments and the blog they belong to or you create a table for every blog with the comments. Which of these is the best in terms of how dificult it is to implement and how memory consuming it is? -
Instance continues to Fail Health check after python3 and Ubuntu 18.04 update (Django+Nginx+Uwsgi)
My Django + uwsgi + Nginx app has failed for days now and I am not sure what is happening. It seems that my Nginx health check seems to be okay and my Django App is functioning correctly.

I need to upgrade me code for DRY and easy refactoring in future

AttributeError on <module '__main__' when deploying app on Heroku via Gunicorn
I am new to Django/Heroku but am trying to launch my first project with these tools that includes a pre-trained SK model and custom Pipelines. I've got everything working fine locally but when I try to push to Heroku I keep receiving 500 errors and my log tail is posted below. I can't seem to solve it. My custom transformer pipeline that I wrote has a class called FeatureSelector as well as CategoricalTransformer, which I've pasted into the manage.py file (as someone suggested doing that, and I didn't know where else they might go). Heroku, or gunicorn, or something seems to have issues with this. AttributeError: Can't get attribute 'FeatureSelector' on <module '__main__' from '/app/.heroku/python/bin/gunicorn'> I've tried renaming the apps.py file, putting the pipeline in WSGI, moving the joblibs etc. but nothing seems to work for me.

Django: How to efficiently add objects to ManyToManyFields of multiple objects?
We have a student and class many to many relation, where a student can take multiple classes, and a class can be taken by multiple students. class Class(models.Model): name = models.CharField(null=False, max_length=128) class Student(models.Model): first_name = models.CharField(null=False, max_length=64) classes = ManyToManyField(Class) What is the fastest way to add some object or a whole QueryList (in our case: all classes with Biology in their name), to the ManyToManyField of each object in another QueryList (in our case: all students whose first name is Linus)? The current way I am doing it is: biology_classes = Class.objects.filter(name__contains='Biology') linuses = Student.object.filter(first_name='Linus') for linus in linuses: linus.classes.add(*biology_classes) Which I guess hits the db for each student. I wonder if there is maybe some way to do it all "at once". Maybe something that looks something like this: linuses.classes.add(*biology_classes) # (this does not work) -

Control of interaction with web system
I am creating a website with several dashboards to view the progress of their activities. But I must also create a profile where the administrator performs an access control per user through graphics. Example: • User lists • Number of accesses per user (daily) • Amount of download per user (pdf) • Interaction time per graph (Optional) • Interaction time with the app • Alerts when a user produces below average. • Assignment of roles • Assignment of equipment The language I am using is python, django and javascript. is there an example where it allows me to perform this control.? I would really apreciate it. Greetings. -

Django - CSRF cookie not set when logging using Ajax
I'm creating a separated Vue/Django app where Vue handles the whole frontend and communicates with Django using JSON, Vue is standalone and it's not rendered by Django. Since i don't want to lose the benefits of the built-in Django Session Authentication and keep using django-allauth (which supports AJAX), i'm setting up both backend and frontend and same server and on same port. Right now i'm trying from my dev environment to setup authentication, but i've been going in circles for the whole day without managing to do it. I keep getting the following error: [23/Mar/2021 17:46:55] "OPTIONS /accounts/login/ HTTP/1.1" 200 0 Forbidden (CSRF cookie not set.): /accounts/login/ Here is my Vue/Axios code: get_csrf() { axios.get('http://127.0.0.1:8000/get_csrf/') .then(response => { this.csrf_token = response['data']; }); }, authenticate() { this.get_csrf() axios.post('http://127.0.0.1:8000/accounts/login/', { username: 'root', password: 'test', }, { headers: { 'X-CSRFTOKEN': this.csrf_token //I also tried X-CSRFToken instead, same outcome.. }, }) .then(function (response) { console.log(response) }.bind(this)) }, The function get_csrf is used to retrieve a csrf cookie from a endpoint in my Django app. My Django settings.py code: CORS_ALLOW_HEADERS = list(default_headers) + [ 'xsrfheadername', 'xsrfcookiename', 'content-type', 'x-csrftoken', 'X-CSRFTOKEN', ] CORS_ALLOW_CREDENTIALS = True CORS_ALLOWED_ORIGINS = [ "http://localhost:8080", "http://127.0.0.1:8080", "http://localhost:8000", "http://127.0.0.1:8000", ] CSRF_TRUSTED_ORIGINS = [ "http://localhost:8080", … -

Django: how to order a queryset by a related object if it exists and by a field if it doesn't?
I have two models: class Product(models.Model): name = models.CharField(max_length=200, blank=False) price = models.DecimalField(max_digits=100, decimal_places=2, blank=False) class Meta: verbose_name = 'product' verbose_name_plural = 'products' class PromotionPrice(models.Model): product = models.ForeignKey(Product, related_name='promotion_prices', on_delete=models.CASCADE, null=False) price = models.DecimalField(max_digits=100, decimal_places=2, blank=False) start_date = models.DateTimeField(blank=False) end_date = models.DateTimeField(blank=False) class Meta: verbose_name = 'promotion price' verbose_name_plural = 'promotion prices' I want an efficient way to order all the Product objects by the price, taking into account the promotion price if it exists. E.g. I have the following list of Product objects: [ { id: 1, name: "Apple", price: "5.00", promotion_prices: [] }, { id: 2, name: "Banana", price: "10.00", promotion_prices: [] }, { id: 3, name: "Orange", price: "15.00", promotion_prices: [ { product: 1, price: "9.00", start_date: "2021-03-20T00:00:00Z", end_date: "2021-03-20T00:00:00Z" } ] } ] I want the result of ordering to be "Apple", "Orange", "Banana", because "Orange" has a promotion price on it. I'm dealing with thousands of objects, so sorting using sorted() takes ages. -
Best way to save all actions in an application with Django
I would like to save all actions that my staff doing in my application. I could save a report when all function are called, however, I want to save all the actions that was doing in this function. For example, if you update one field in some form, I would like to save what forms are updated. What is the best way to do it? Manual? Is there some library that help me to do it? I did not find any.

How to expand accordian with url in Django template
I'm adding some FAQs to our product pages with the use of a Bootstrap (v5) accordian. If asked a question by a potential client in an email, I want to be able to send them the URL that takes them directly to the answer and expands the accordian item. Each FAQ is loaded from a Django model. The ID from each FAQ is the variable I want to use for each accordian item. I've looked at some other answers on here but can't seem to figure out how to write the script needed for my specific use case. I know nothing about JQuery so haven't included scripts I've found while searching for the answer as they're likely unhelpful. This is my HTML: <section class="bg-white" style="padding: 3rem"> <div class="container"> {% if faqs %} {% for service in services %} {% with name=service.0 %} <h3>{{ name }}</h3> <hr> <!----------------------- ACCORDIAN ------------------------------------------------------------> <div class="accordion accordion-flush mb-3" id="accordionFaq-{{ name }}"> {% for q in faqs %} {% if q.related_service|lower == name|lower %} <div class="accordion-item"> <h3 class="accordion-header" id="faq-heading-{{ q.id }}"> <a class="accordion-button collapsed" data-bs-toggle="collapse" href="#faq-{{ q.id }}" aria-expanded="false" aria-controls="faq-{{ q.id }}"> {{ q.question }} {{ q.id }} </a> </h3> <div id="faq-{{ q.id }}" class="accordion-collapse collapse" … -
