How to secure media files in django in poduction?

From Laravel to Django questions
I have been a Laravel developer for the past years, and I made most of my projects using Laravel. But now I'm working on a project that it needs a recommendation system and after looking around the web I found out that there's no Laravel package for this purpose and the best thing to do is to use python, and after doing a lot of research I think the best python framework to develop backend servers for a website or an application is Django. But to move from PHP Laravel to Python Django it's kinda hard to find the answers of the questions since the diffent ecosystem they, have and after doing searches on google I can't find the answers. so I have these questions I hope someone answer it one by one as I wrote it: 1- can I use any python packages with Django? like in Laravel you can use any php package using composer, or you can only use the packages in Django package system? 2- If one day moved to another Python framework like Flask, can I use the packages developed for Django? 3- I know Django does not support Rest API, do I have to … -

How to get current base urls path of django app
I'm making a reusable Django app, let's say its name is Polls. This app is supposed to work properly no matter where it's being configured in the urls.py of its parent app. Consider the following structure just like that in the Django tutorial mysite/ manage.py mysite/ __init__.py settings.py urls.py asgi.py wsgi.py polls/ __init__.py urls.py admin.py apps.py models.py views.py So, the polls app has its own urls.py and its own views.py which can be linked to any other app, such a mysite by adding a line to mysite/mysite/urls.py such as line 5 in this example urls.py: from django.urls import path, include urlpatterns = [ path('polls/', include('polls.urls')) ] In this example, all views of the polls app will have a link like https://somedomain.com/polls/the-relative-page-link However, the polls app should still function correctly even if we edited line 5 in the above code to other base path such as: urlpatterns = [ path('another-path/', include('polls.urls')) ] So that would change the like to https://somedomain.com/another-path/the-relative-page-link My problem is that some of the views of the "polls" app contain custom javascript code that communicate with another view that represents a server-side API. So in order for this communication to work properly regardless of whether polls URLs are … -

django: replace values() with filter() or only() but sum in same row
I got a query currently looking like this: a = InventoryStatus.objects.values("city").annotate(Sum("a")).annotate(Sum("b")) city is a choicefield, which means I need to do get_FOO_display() on it, but I can't as values() returns a non-query set of a list of tuples, so everything’s evaluated there already. If I change values() to filter() or only() it works, but assuming I got 2 db inputs, one adding 500 to a and one adding 500 to b, then it would create two rows in my table in the template, instead of summing both fields in same row. How could I get the value from my choicefield and sum both values in the same row? -
Referencing twice related field for django model query
So I am using Django to construct a Query and I have 3 models as defined: class Book(models.Model): ... class Upload(models.Model): ... book = models.ForeignKey(Book, on_delete=models.CASCADE) class Region(models.Model): ... page = models.ForeignKey(Upload, on_delete=models.CASCADE) Given these 3 models I wanted a query that lists all the books and annotate them with a segmented_pages variable that contains the count of all the Upload that have non-zero number of regions. Basically, counting the number of uploads per book that have atleast one region. I am assuming the basic structure of the query would look like this and mainly the logic inside filter needs to be modified as there is no convenient count lookup. Book.objects.annotate(segmented_pages=Count('upload', filter=Q(upload__region__count__gt=0)) Can someone please help me with the logic of the filter and a simple explanation of how to go about designing these types of queries using django models?
