Deployed Django - project static files css only working for some
I have a question regarding Django's handling of static files. I deployed a Django project on Heroku and use following Procfile web: python3 manage.py collectstatic --noinput; gunicorn testapp.wsgi --log-file - I have a list of different css files which all worked for one html template (applies the style changes). Now I added a second html template which uses the same css files. However, for this file only some css files are discovered while others are completely ignored. For example (one working while the other doesn't) href="/static/css/sidesection.dd3c29e22478.css" --> applies the style changes href="/static/css/checker.5ffe0baa6d94.css" --> does not apply the style changes Does someone have experience regarding this matter and could eventually also provide an explanation? This issue is not the more common issue where the static files do not load at all. It loads all of them for one html but not all for another. -
how to integrate Stripe in my web app without creating products on Stripe dashboard
I have a web app (Angular 8, Django 3) that allows one set of users to create products with whatever price they seem fit. And a second set of users that is going to load these products into the cart and purchase them. All I want Stripe to do is process the card payment for a certain amount (determined by my backend/server side). On the Stripe website it says I have to create products and prices in the "Accepting One Time Payment" section (https://stripe.com/docs/payments/checkout/accept-a-payment). I dont want to do this. I just want to process a payment for an amount that I determine. From the Stripe documentation it says to create a checkout session: const stripe = require('stripe')('sk_test_UO9wbdk2YOZaQK9dDubCYwSO00RIV3STO8'); const session = await stripe.checkout.sessions.create({ payment_method_types: ['card'], line_items: [{ price: '{{PRICE_ID}}', quantity: 1, }], mode: 'payment', success_url: 'https://example.com/success?session_id={CHECKOUT_SESSION_ID}', cancel_url: 'https://example.com/cancel', }); Could i just change the line_items object to have a price that is what I determined on my server and a quantity of 1 to get around this? -

Confusion while using the django-celery-beat to perform some task periodically?
I am learning how to implement celery in django. I want to use the custom scheduler classes to schedule the task from the database so I used the django-celery-beat. But for this I am not using schedular from the database just to check whether it works or not since it is my first time with celery. I placed the celery.py , init.py , tasks.py files as in the django-celery-beat documentation. But I got no idea how to write the tasks and the views. For example I want to create task object in the database every 1 minute so I wrote the views for this with some django logic and I implemented scheduler like this but it is not working. In the console it is throwing this error. celery.beat.SchedulingError: Couldn't apply scheduled task run_every_1_minutes: add_task() missing 1 required positional argument: 'request' What would be the right approach in this example i.e. to create the task object every 1 minute ?How can I write views.py and tasks.py file for this? celery.py inside settings directory from __future__ import absolute_import, unicode_literals import os from celery import Celery # set the default Django settings module for the 'celery' program. from django.conf import settings os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'celery_demo.settings') … -

Login Required decorator not redirecting to login url | Django
@login_required decorator not redirecting me to logging page When I click the add to cart button it doesn't redirect me to the login page. It just doesn't do anything. I tried the login required decorator in another function. Like the home view action. And when I try to access the home page it directly redirects me to the login page. But in the combo_add_to_cart it doesn't seems to work. But I have found something in the terminal. I have seen that when I click the add to cart button it first sends a post request of "POST /carts/cart/combo/add-to-cart/ " then it sends a get request "GET /accounts/login/?next=/carts/cart/combo/add-to-cart/". accounts views.py class Login(FormView): form_class = LoginForm success_url = '/' template_name = 'accounts/login.html' def form_valid(self, form): request = self.request next_ = request.GET.get('next') next_post = request.POST.get('next') redirect_path = next_ or next_post or None email = form.cleaned_data.get('email') password = form.cleaned_data.get('password') user = authenticate(request, email=email, password=password) if user is not None: login(request, user) if is_safe_url(redirect_path, request.get_host()): return redirect(redirect_path) else: return redirect("/") return super(Login, self).form_invalid(form) cart views.py @login_required(login_url='/accounts/login/') def combo_add_to_cart(request): combo_id = request.POST.get('combo_id') if combo_id is not None: try: combo_obj = Combo.objects.get(id=combo_id) except Combo.DoesNotExist: return("carts:cart") combo = combo_obj cart_item, created = ComboCartItem.objects.get_or_create( combo=combo, user=request.user, ordered=False ) cart_obj, … -

Angular loading files from backend using the wrong port
My Angular frontend application is using default port 4200. My Django backend application is running on port 8000. Frontend can upload files and images to backend, a then get their links to show on page. Uploading is working fine, but then when I try to get images from backend, Angular is downloading them from frontend port 4200 and all views are breaking, because there is no such files on that path. Briefly, I need file path in that way - http://localhost:8000/media/uploads/myfile, but I get http://localhost:4200/media/uploads/myfile. I use proxy to get backend api: { "/api": { "target": "http://localhost:8000", "secure": false } } I do not know where the problem may be. -
django allauth custom signup form not rendering
Background I have two types of users, buyers & sellers, mapped to an extended AbstractUser via a OneToOneField. I want to request different information from them upon sign up, so I extended the allauth SignupForm as described in this helpful post. I have two routes, accounts/signup/user and accounts/signup/seller, which links to the BuyerSignupView and SellerSignupView respectively. The two views extend the allauth SignupView but instead renders custom templates that use my custom forms. Problem The forms aren't rendering at all on the webpage. Clicking inspect on the web shows no html tags related to the form, but calling form.as_p() in the python shell correctly converts my form to its corresponding html components. # view.py class UserSignupView(SignupView): template_name = "accounts/user_signup.html" form_class = UserSignupForm class SellerSignupView(SignupView): template_name = "accounts/seller_signup.html" form_class = SellerSignupForm # forms.py class UserSignupForm(SignupForm): GENDER_CHOICES = [("F", "Female"), ("M", "Male"), ("O", "Other")] AGE_CHOICES = [ ("A", "18-"), ("B", "18-25"), ("C", "25-35"), ("D", "35-45"), ("E", "45+"), ] first_name = forms.CharField(max_length=30, label="First Name") last_name = forms.CharField(max_length=30, label="Last Name") gender = forms.ChoiceField(choices=GENDER_CHOICES, required=False, label="Gender") age = forms.ChoiceField(choices=AGE_CHOICES, required=False, label="Age") phonenumber = PhoneNumberField() def signup(self, request, user): user.first_name = self.cleaned_data["first_name"] user.last_name = self.cleaned_data["last_name"] user.save() new_profile = Profile( user=user, # TODO - add followed_tags = … -
