While mutating shares of a Post, I get "Variable '$postId' got invalid value {'isTrusted': True, '_vts': 1714830156331} ID cannot represent value
Using Vue 3 and Django backend using Graphql, I want to count button click shares.The problem is referring to PostId of Post model in django and graphene-django gives me error: "Variable '$postId' got invalid value {'isTrusted': True, '_vts': 1714830156331} ID cannot represent value. How can I refer to PostId from the Django database? In SocialMediaButtons.vue: const toggleShares = (postId) => { navigator.clipboard.writeText(window.open (shareUrl, '_blank')); copied.value = true; console.log('Post Shared!'); store.toggleShares(postId); }; And using Pinia state management I have userInteraction: toggleShares(postId) { const postStore = usePostStore(); const post = postStore.getPostBySlug(postId); if (post) { const url = window.location.origin + '/post/' + post.slug; window.open(url, '_blank'); } this.shares += 1; // Increment shares count console.log('Share button clicked.

LoginRequiredMixin not work Properly with login URL
I'm working on a Django project where I have implemented a ListView to display a list of checkout items (ListCheckoutView). I want to require authentication for accessing this view, but currently, it's accessible even without logging in. I've tried using the LoginRequiredMixin, but it doesn't seem to be working as expected. In the checkout.html works properly from django.urls import path from .views import BooksListView, BooksDetailView, BookCheckoutView, OrderComplete, SearchResultsListView, ListCheckoutView urlpatterns = [ path('', BooksListView.as_view(), name='list'), path('books/', ListCheckoutView.as_view(), name='list2'), path('<int:pk>/', BooksDetailView.as_view(), name='detail'), path('<int:pk>/checkout/', BookCheckoutView.as_view(), name='checkout'), path('complete/', OrderComplete, name='complete'), path('search/', SearchResultsListView.as_view(), name='search_results'), ] from django.views.generic import ListView from django.contrib.auth.mixins import LoginRequiredMixin from .models import Book, Order class ListCheckoutView(LoginRequiredMixin, ListView): model = Book template_name = 'base.html' login_url = 'login' class BookCheckoutView(LoginRequiredMixin, DetailView): model = Book template_name = 'checkout.html' login_url = 'login' -
Django Form - POST method not recognised as POST in views
In my django project, I am trying to create a form which the user will access through a specific url. By clicking on the url, the user will be automatically redirected to a pager_id. Inbetween the user click on said url and being redirected to page_id, a form will be passed in the background, without any template. Slight problem, the form does not pass the if request.method == "POST":. I know that because the print rendered in the console is this is not a post request. I think its the probably the first time Im not using a template to render theform. I would normally specify something like: <form "method="POST"> {% csrf_token %} </form> Question: Assuming this what is causing problem: Does Django require to use a template to render the form? Or is there a way to specify method="POST" in a different way? Or is there something else I am not seeing? views.py def function(request, page_id): form = myform(request.POST) if request.method == "POST": print('this is a post request') if form.is_valid(): data = form.save(commit=False) ... data.save() return redirect('page', page_id=page_id) else: form = myform() print('this is not a post request') #<-- this is what gets printed in the console else: print('Come … -

Setting DateTimeRangeField programmatically via a ModelForm
I'm trying to set the DateTimeRangeField in a Django ModelForm form, but I'm getting a validation error "this field is required". It seems that Django is not recognizing nor psycopg2.extras.DateTimeTZRange instance, nor any date strings as a valid value. How can I set the value of DateTimeRangeField? Striped down example: # models.py from django.contrib.postgres.fields import DateTimeRangeField class Reservation(models.Model): range = DateTimeRangeField() # forms.py class ReservationForm(forms.ModelForm): class Meta: model = Reservation exclude = [] # test.py from psycopg2.extras import DateTimeTZRange form = ReservationForm(data={ 'range': DateTimeTZRange( lower='2024-04-21 10:00', upper='2024-04-21 11:00' ) }) if form.is_valid(): form.save() else: print(form.errors.as_data()) Output: {'range': [ValidationError(['This field is required.'])]} -
How to manage language redirection in Django middleware with user authentication?
I am developing a middleware in Django to manage language redirection based on the user's language preference, which can be stored in the database or specified in a cookie. The middleware needs to handle URLs that include a language prefix, ensuring they match the user's preferred language, especially after the user logs in. The middleware is designed to redirect users to the correct language version of a page. However, when a user logs in and a next parameter is used to specify a redirect URL, the language prefix in this URL sometimes does not match the user's preferred language. This results in users being redirected to the default language instead of their preferred language. Here is the middleware implementation: from django.http import HttpResponseRedirect from django.utils.http import urlencode from urllib.parse import urlparse, urlunparse, parse_qs from django.utils.translation import activate class UserLanguageMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): response = self.get_response(request) excepted_paths = ["/stripe/", "/api/", "/media/", "/static/", "/set-language/"] if any(request.path.startswith(path) for path in excepted_paths): return response preferred_language = None if request.user.is_authenticated: preferred_language = getattr(request.user, "language", None) if not preferred_language: preferred_language = request.COOKIES.get(settings.LANGUAGE_COOKIE_NAME, "en") activate(preferred_language) current_cookie_language = request.COOKIES.get(settings.LANGUAGE_COOKIE_NAME) if current_cookie_language != preferred_language: response.set_cookie( settings.LANGUAGE_COOKIE_NAME, preferred_language, max_age=365 * 24 * 60 * … -

Ways to providing data to your frontend
As I progress with the backend development of this website ( with django and DRF but i don't think it matters in this question), I've come across a question regarding the organization of API endpoints, particularly with regards to providing data for the frontend. My goal is to ensure that the backend implementation is both standard-compliant and optimized for performance. For example, let's consider the structure of the homepage of the website. The frontend will display various components such as banners, most popular services, newest products, and potentially other unrelated data * unrelated in terms of they are separate entities in database). While I have separate endpoints for products and services and .., I'm uncertain whether this approach is suitable for the homepage. My main concern is whether it's preferable to maintain separate endpoints for products and services, potentially requiring the frontend to make multiple requests to gather all the necessary data for the homepage. Alternatively, should I consider consolidating the data needed for the homepage into a single endpoint to streamline frontend data retrieval? I'm seeking advice on best practices for structuring API endpoints in this scenario. Are there established conventions or guidelines for organizing endpoints in a way … -

How to properly set up React proxying on a Chromebook?
I am running a Django backend app on port 8000 and would like to configure a React app proxy calling that particular Django backend app. I have added "proxy": "http://localhost:8000", to package.json and used shorthand url notations (such as /api/products) in the axios calls. This setup works fine when running both the React app and the Django app on a Debian machine. However, the same setup fails on my Chromebook (Lenovo Chromebook Duet 2000) with error: > frontend@0.1.0 start > react-scripts start Invalid options object. Dev Server has been initialized using an options object that does not match the API schema. - options.allowedHosts[0] should be a non-empty string. Attempted to replace the proxy setup with "proxy": "http://127.0.0.1:8000", to no avail. Please let me know what is the culprit and how to make proxying work in this particular case! -

Django & dependency injection
In the past, I've used dependency-injector, but it looks like it's unmaintained now. :-( Does anyone have any good suggestions for a DI package? I'd want to be able to inject dependencies into views, with the ability to inject mocks in view tests. -

How to set manifest_storage for ManifestFilesMixin (Django)
I use django-storages to serve my static files from S3. I want to use the ManifestFilesMixin for cache busting my CSS and JS files. The following works fine: from django.contrib.staticfiles.storage import ManifestFilesMixin from storages.backends.s3boto3 import S3Boto3Storage class ManifestS3Storage(ManifestFilesMixin, S3Boto3Storage): pass Except that staticfiles.json is placed in my S3 bucket. I don't want this as explained here. The Django docs mention that it is possible to give a "manifest_storage" argument to the ManifestFilesMixin but I don't know how to do this. The docs mention how to do it for the ManifestStaticFilesStorage class but I don't understand how to do this for the ManifestFilesMixin.
