Getting Intermittent 403 error while making a fetch request from JS
I am trying to call a POST API via fetch await in JS which sometimes gives 201 and sometimes it gives 403. const apiCalls = number_arr.map(async (event) => { const response = await fetch(`{% url 'base_check_url' %}?number=${event.attrs.value}`, { method: "POST", credentials: 'include', headers: {'Content-Type': 'text/plain'}, }); APIs are written using django framework Attaching screenshot of error response logged in console: This is an intermittent issue, if I hit the API via JS 10 times, 70% of the time I would get 403. Also, do let me know if any other info is required to debug this issue. Thanks in advance. -

Gym system managment [closed]
I need to develop a financial control system for a gym and also include student registration. Because of this, I am unsure about which programming language to use. I have more knowledge in Javascript and Python, but I have also studied a bit of PHP and C#. While searching on the internet, I found that most gym management systems are developed in PHP or C#. However, I had in mind to use React with TypeScript for the front-end, and I am uncertain about what would be more feasible for the back-end: Node, Django, PHP, or C#. Some things I need to implement in the future include printing documents, a mobile app, and integration with a turnstile system. These are some factors that will weigh in on the decision, as the chosen language needs to be compatible with these elements to avoid headaches when implementing them in the future. Does anyone have any suggestions? As I have more expertise in TypeScript and Django, I am considering using one of these two options. However, if another option is deemed necessary, that wouldn't be a problem. -
Database trigger on update, remove, create
I want some code to be executed after every change in the database in a specific table. Meaning, if an entry was inserted, removed or updated. I found this https://stackoverflow.com/a/15712353/2813152 using django signals. Is this the recommended way for this? Can I use it for any changes at this table? Not just when an instance is saved? Can the code run async in the background? -

How to ensure that my Django view ouputs a file download?

Can i disable default ordering in Django admin panel?
I'm trying to use 'liczba_glosow' field for ordering in Django admin panel. The problem is that the model itself has ordering by "numer_na_liscie" in Meta method and admin uses default ordering and than 'liczba_glosow'. I would like admin to use ONLY order_by("-_liczba_glosow") and bypass default. I can't use simple ordering="liczba_glosow" because this field is created only for admin display purpose and it's not part of a model itself. class KandydatDoSejmuAdmin(admin.ModelAdmin): list_display = ("imie_nazwisko", "numer_na_liscie", "okreg_wyborczy", "komitet_wyborczy", "liczba_glosow") raw_id_fields = ("okreg_wyborczy", "komitet_wyborczy") list_filter = ("komitet_wyborczy__nazwa", "oddanyglos__kod_pocztowy__wojewodztwo", "okreg_wyborczy__nazwa",) search_fields = ( "imie_nazwisko", "okreg_wyborczy__nazwa", "komitet_wyborczy__nazwa", "oddanyglos__kod_pocztowy__wojewodztwo") list_per_page = 10 def liczba_glosow(self, obj): return obj.oddanyglos_set.count() liczba_glosow.admin_order_field = "_liczba_glosow" def get_queryset(self, request): qs = super().get_queryset(request) return qs.annotate( _liczba_glosow=Count("oddanyglos__kandydat") ).order_by("-_liczba_glosow") According to Django docs: Set ordering to specify how lists of objects should be ordered in the Django admin views. This should be a list or tuple in the same format as a model’s ordering parameter. If this isn’t provided, the Django admin will use the model’s default ordering. According to the above provision, any attempt to disable the default sorting like ordering=None, get_ordering() returning None or empty list doesn't work. Is there an option to override the default sorting in the admin panel without interfering … -
Migrate `DateTimeField` to `DateField` in Django

Integrating Django and Socket Communication in a Kivy Chat Application
I've developed a chat application using Kivy. Within the application, the server and client establish communication via pythons built-in socket. While it functions adequately, I'm considering incorporating Django on the server side. Navigating through various libraries like pythons built-in socket, Django WebSocket, and websockets has left me somewhat perplexed. I would greatly appreciate your assistance in clarifying at least one of the following queries: 1- Could you elucidate the distinctions between pythons built-in socket, socketio, and websockets in Django, as well as the websockets library in Python? 2- Is it feasible to employ different libraries on the client and server sides, such as using pythons built-in socket (or websockets) on the client side and Django WebSocket on the server side? 3- Does Django Channels offer support for Python's native socket, rather than relying exclusively on channel websockets? 4- Is it plausible to integrate Django into a Python chat application centered around pyhon socket, leveraging its functionalities for user authentication, database management, and static content handling in conjunction with real-time communication? -

Is there a way to 'concatenate' a raw sitemap.xml with the generated in django sitemaps?
Django has a built in sitemaps app that create a sitemap.xml, but I need to integrate with another django project that has it's own sitemap.xml. So, the idea it's to make a call to https:another-django-project/sitemap.xml and with that xml 'append' to my django project sitemap.xml and use that as sitemap. There are 2 projects, in different containers, works like one site(one Web, one Wagtail) mysite.com. So, in mysite.com/sitemap.xml should return all info from both I've tried to implement the class WebSitemap(DjangoSitemap): and override something like 'generate_xml()' so I could make a http call to the another application and append the xml, but that doesn't exist. I've tried to make my own view that calls the django sitemaps programmatically, make a call to the another application xml, concatenate and return. doesn't look a good approach. how can I do that? -
VSCode, Django and javascript: Why does VSCode indicate an error when I use {{ }}?

I can't use quotes there because these are lists, not strings. Am I doing it wrong, despite of the code working? What should I do to correct it? -
django on update modelform not presenting stored value as selected
I have an uninteresting modelform. One of the model fields, occupation, is a foreignkey to a table containing a long, long list of options. The problem is for update, the rendered form, which is rendered via crispy, does not set focus to the stored value (mark it as the selected option in the <select><option...> code). Instead, it shows the empty choice. I see the initial value does point to the id of the database's record. To make this a little more "interesting," I want to change occupation.to_field_name to occupation.code (a charfield). I've been futzing with the form's init as given below. I can convert the option values to the form I want, but I cannot get the form to present the stored value as selected (and present as the field's selected value). How do I do this? Do I have to do it via JS or am I doing something wrong with the form?
