Tailwind-Django SIte - Extending base.html causing strange table behaviour with For Loops

I want to create a script that takes a list of values as input and outputs a python file (django)
I'm doing a lot of work that is comparable to data entry -- essentially copying functions from one script to use for something that only differs in the names of the attributes. Like: Script 1: Business.objects.create( field_cat=something["cat"], field_doggo=something["doggo"], field_birb=something["birb], ) Script 2 OtherBusiness.objects.create( field_catto=something["catto"], field_dog=something["dog"], field_bird=something["bird"], ) This is a very simplified version of what I'm talking about. These scripts range from 60-90 lines long each. I'm getting tired of this monotonous work of replacing attribute names for dozens of files. There has got to be another way. Can anyone lend some insight? -

Django How to use Javascript file from my local Django project in an external app
Let's say I have an application, myapp, and in that application I have installed another application via pip install wiki to add a wiki into my project. The wiki app is installed in the following directory: /Users/{my_username}/.virtualenvs/{my_virtualenv_name}/lib/python3.9/site-packages/wiki/ So to make modifications I have to overwrite the templates. In myapp I have been able to modify without problems the styles and others of the wiki app by overriding the templates, but the problem comes when I want to load javascript libraries external to wiki and that are in my local project (myapp) I would like to add the following js, but for some reason it doesn't work: <script type="text/javascript" src="/static/myapp/bootstrap/js/bootstrap-typeahead.js"> </script> <script type="text/javascript" src="/static/myapp/scripts/jquery.autocomplete.min.js"> </script> <script type="text/javascript" src="/static/myapp/scripts/myapp.js"></script> <script type="text/javascript" src="{% static 'project/search.js' %}"></script> <script type="text/javascript" src="{% static 'myapp/scripts/underscore-1.8.3.min.js' %}"> Probably if i add those js files in site-packages it will work but I don't think its good practice. Any ideas or suggestions on how to import such js files correctly? -

Django Stripe library is having trouble with Payment Method
I am using Stripe JS on my front end, and sending it to my backend, which is based on Django. All of generating a subscription is working, except for the payment method. Here's the code: class PurchaseSubscriptionView(APIView): def post(self, request, user_id): price_name = request.data.get("price_name") payment_method = request.data.get("payment_method") user = User.objects.get(id=user_id) customer, created = djstripe.models.Customer.get_or_create(subscriber=user) customer.add_payment_method(payment_method) price = djstripe.models.Price.objects.get(nickname=price_name) customer.subscribe(price=price) return Response({"success": "eventual subscription data"}) My payment_method looks like this (all of this is fake card data): { "id":"pm_1Ia7gGJs57u3g5HDEpaI5Pv2", "object":"payment_method", "billing_details":{ "address":{ "city":"None", "country":"None", "line1":"None", "line2":"None", "postal_code":"None", "state":"None" }, "email":"None", "name":"None", "phone":"None" }, "card":{ "brand":"visa", "checks":{ "address_line1_check":"None", "address_postal_code_check":"None", "cvc_check":"None" }, "country":"US", "exp_month":2, "exp_year":2022, "funding":"credit", "generated_from":"None", "last4":"4242", "networks":{ "available":[ "visa" ], "preferred":"None" }, "three_d_secure_usage":{ "supported":true }, "wallet":"None" }, "created":1616972764, "customer":"None", "livemode":false, "type":"card" } However upon this line: customer.add_payment_method(payment_method) I get the following error: TypeError: quote_from_bytes() expected bytes What exactly am I missing here? Is this not how I am supposed to use a payment method? This is using the Djstripe library -
Django Reverse function not working in this example
I'm not able to access the url named "forum" using the reverse function. It gives me this error: django.urls.exceptions.NoReverseMatch: Reverse for 'forum' not found. 'forum' is not a valid view function or pattern name. I'm able to access all my other namespaces URLs within the other apps. But I just can't access anything by name from my root URLs.py file. Here is my root URLs.py file from django.contrib import admin from django.urls import path, include from machina import urls as machina_urls from django.conf.urls.static import static from django.conf import settings urlpatterns = [ path('forum/',include(machina_urls), name='forum'), path('admin/', admin.site.urls), path('symposium/', include('symposium.urls')), path('elearning/', include('elearning.urls')), ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) -
Efficient Django query filter first n records
I'm trying to filter for the first (or last) n Message objects which match a certain filter. Right now I need to filter for all matches then slice. def get(self, request, chat_id, n): last_n_messages = Message.objects.filter(chat=chat_id).order_by('-id')[:n] last_n_sorted = reversed(last_n_messages) serializer = MessageSerializer(last_n_sorted, many=True) return Response(serializer.data, status=status.HTTP_200_OK) This is clearly not efficient. Is there a way to get the first (or last) n items without exhaustively loading every match? -
Using python manage.py runserver is giving me "file or directory does not exist"
So I keep getting that message and I am in the right folder when doing the command. I pip install django'd, I ran the command django-admin startapp firstproject, but this problem persists. I even tried updating django and python and reinstalled everything once. The photo I've attatched are the contents of my projects directory. Has anyone else had this problem before?
