Django, "render" returns a POST request and not GET after a POST request
I'm having my view def my_wishlist(request): user = request.user user_products = WishlistProductPrices.objects.filter(user=user).all() ### Create filters ### filter = get_user_filter_fields_wishlist(user_products) filter = filter(request.GET,queryset = user_products) if request.method == "POST": post_form = MyForm(request.POST) if post_form.is_valid(): #do stuff form = MyForm() context = { "form":form, "filter":filter } return render(request, "myapp/add_wishlist.html",context=context) #Returns POST, seems like else: #invalid post_form context = { "form":post_form, "filter":filter } return render(request, "myapp/add_wishlist.html",context=context) else: #Get request form = MyForm() context = { "form":form, "filter":filter } return render(request, "myapp/add_wishlist.html",context=context) it works like a charm, but after the user has submitted something, and presses F5 the "do you want to resend the information again" pops-up. I find it weird, since I assume the render(request,"mypp/add_wishlist.html) ad the bottom of the page would return a GET request? -
My CSS files are not getting loaded from my S3 bucket, why?
Here's my S3 configurations: STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME') AWS_QUERYSTRING_AUTH = False I have a couple of models that have ImageFields and when I upload an image it properly gets uploaded to my S3 bucket. But I also want to put my staticfiles there (JS, CSS). I have manually created a folder in the root of my S3 bucket called static and I have uploaded all of my CSS, JS files to that folder using S3's web app. However, in my template I am simply doing {% static 'css/main.css' %} and the file is not getting loaded. I used Chrome's inspect tool to check which resources are being loaded and I think it gets connected to my S3 bucket, but brings the file I want empty, so it is not getting loaded for some reason. enter image description here -
How can Django get session data in next request?
def home(request): # logged in if request.user.is_authenticated: request.session['username'] = str(request.user) request.session.set_expiry(0) # anonymous else: # how could Django get session data here ? cur = request.session.get('username', None) if cur: pass else: anon = random.choice(settings.SESSION_NAMES) request.session['username'] = anon request.session.set_expiry(42) res = render(request, 'ex/home.html', {'username': request.session['username']}) return res I'm trying to understand about session. In anonymous case above, I set session data 'username' to request that is already obtained. And in next request (after refreshing), I can get session data. But I don't understand how could it work. It's a new request, and I set 'username' in prev request, not response. How could I get 'username' from next request object despite not setting it to previous response object? -

Tags imported but relationship not imported with django-import-export
I am trying to import a csv file with quotes and tags into my django-taggit custom tag model following https://docs.wagtail.io/en/stable/reference/pages/model_recipes.html#custom-tag-models.

Including two Inclusion Tags in Template Tag
Possibly the wording of my initial question is wrong, I was really unsure how to word it. Here is my current code. product_display.py from django import template from categorytree.models import CategoryTree register = template.Library() @register.inclusion_tag('templatetags/product_display.html') @register.simple_tag(takes_context=True) def this_shows_products(category, **kwargs): try: return {'ProductsModel': CategoryTree.objects.all().filter(title=category).first().products.all()} except: pass product_display.html {% load static %} <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> </style> </head> {% load product_display %} <div class='row'> {% for obj in ProductsModel %} <div class='col-xs-12 col-sm-12 col-md-6 col-lg-3 col-xl-2 col-xxl-1 ' style="margin-bottom:15px; margin-top:15px"> {% include 'products/snippets/card.html' with instance=obj cart=cart %} </div> {% endfor %} </div> Depending on the width of the screen, I want to be able to use different HTML templates. I want something like this - If screen width > 1600 then @register.inclusion_tag('templatetags/product_display.html') else @register.inclusion_tag('templatetags/product_display(1).html') end if I tried using pyauthogui, GetSystemMetrics and elsewhere in my code I have $(window).width but so far nothing I have tried has remotely solved this current problem. I could make two separate template tags but was hoping there was a more efficient way of addressing my problem. -

AttributeError: 'QuerySet' object has no attribute 'active' in Django rest framework
I am trying to implement Coupon code feature in Django Rest framework. When a user tries to purchase a product and wants to use coupon codes presented on the item, the user should be able to get a discount based on that coupon code.

Django: how to show a narrowed drop-down list based on the previous selection?
For example I would like make an instance CAR with two information: Manufaturer and CarModel. class Manufacturer(models.Model): name = models.CharField(max_length=10, blank=False) class CarModel(models.Model): name = models.CharField(max_length=10, blank=False) class Car(models.Model): producer = models.OneToOneField(Manufacturer, on_delete=models.CASCADE()) carmodel = models.OneToOneField(CarModel, on_delete= models.CASCADE()) Of course before I would make an instance for class Car I would have to make instances for class Manufacturer and CarModel. I would make BMW, Volvo, Toyota for Manucaturer and then series 3, series 5, X5, X7, XC90, V40, Prius, Land Cruiser, Corolla. Finally when I would make an instance for class Car I would see first: BMW, Volvo, Toyota I would choose Toyota and then I would like see in next drop-down list only: Prius, Land Cruiser, Corolla Of course BMW does not manufature Prius :) How can I do something like filter for that? -

what are the various ways for Styling the Django Forms?
was working with Django forms, and to beautify the Django forms I came across widgets, and after learning it got to know that we can customize widgets in two ways: it can be via widget instance or via widget class. Later came across django-crispy; django-bootstrap. Which will do the same beautification of the forms along with various other advantages over other. But was wondering, how many more such library / packages / apps are there, and is there any short of description for each, which might help me and others too. Thanks -

How do I get User's updated name from Python Firebase Admin SDK?

So I'm trying to make an index.html for the homepage of my Django project. I made an app called pages. Note that the templates folder is empty (moving index.html to templates did nothing). admin.py and models.py also contain nothing. I configured my TEMPLATES settings as such: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'templates'), ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] In my root project folder, urls.py looks like this. from django.contrib import admin from django.urls import path from django.conf.urls import include # from pages.views import home_view urlpatterns = [ path('homepage/', include('pages.urls')), path('admin/', admin.site.urls), path('explorer/', include('explorer.urls')), ] In the views.py file of the pages app: from typing import ContextManager from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): # Render the HTML template index.html return render(request, 'index.html', context=ContextManager) In the pages app (not project root folder), urls.py looks like this (I created this file myself): from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), ] And index.html: <!DOCTYPE html> <title>Test</title> <p>Test</p> Here is the full file structure. Here is what happens when I run the server: Where http://127.0.0.1:8000/ is … -
