QuerySet class does not inherit from TranslatableQuerySet
I'm working on my Django project, and currently I'm working on localization and translating a website. I have a problem with translating my post for blog part. I already have integrated models and everything and I used PublishedManager in order to filter. But now since I used django-parler (from parler.models import TranslatableModel, TranslatedFields), now I got this error which is probably because of TranslatableModel. I have this error: ImproperlyConfigured at /en/admin/main_app/post/ QuerySet class does not inherit from TranslatableQuerySet models.py class Status(models.TextChoices): DRAFT = 'DF', 'Draft' PUBLISHED = 'PB', 'Published' class PublishedManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(status=Status.PUBLISHED) class Post(TranslatableModel): # Your existing fields and methods... # My custom manager published = PublishedManager() # Other methods... How do I solve this? Thanks in advance! -

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".

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 … -

Field Validator not getting called in Model Serializer
I am quite new to Django. I am working on a django app which needs to store films, and when I try to load film instances with the following program: import os import json import requests # Assuming the JSON content is stored in a variable named 'films_json' json_file_path: str = os.path.join(os.getcwd(), "films.json") # Load the JSON content from the file with open(json_file_path, "r") as file: films_json: dict = json.load(file) # URL of the endpoint endpoint_url = "http://127.0.0.1:8000/site-admin/add-film/" for film_data in films_json["films"]: print() print(json.dumps(film_data, indent=4)) response: requests.Response = requests.post(endpoint_url, json=film_data) if response.status_code == 201: print(f"Film '{film_data['name']}' added successfully") else: print(f"Failed to add film '{film_data['name']}':") print(json.dumps(dict(response.headers),indent=4)) print(f"{json.dumps(response.json(), indent=4)}") I get the following response (for each film): { "name": "Pulp Fiction", "genre": "Crime", "duration": 154, "director": "Quentin Tarantino", "cast": [ "John Travolta", "Uma Thurman", "Samuel L.

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! -

many to many serializers error in post api

I use CastSerializer to create post method to create new movie and new cast relationship, but when call post method, response return AttributeError. I want my post body like this: { ...

Complex constraint in a Django model
I have a use case where I want to validate that a field ForeignKey value is in a particular set, so something like: class Role(models.Model): label = models.CharField(max_length=24) class Group(models.Model): roles = models.ManyToManyField(Role, null=False) class Member(models.Model): label = models.CharField(max_length=24) group = models.ForeignKey(Group) role = models.ForeignKey(Role) class Meta: constraints = [ models.CheckConstraint( name="%(app_label)s_%(class)s_role", check=( models.Q(role__in=... valid roles ...) ) ) In other words, only allow a member to have a role if the role is listed in the roles for the group. I can't figure out how to express this. -
403 forbidden error in Django admin even though superuser was already created
Recently, i cloned a project from github to get more familiar with projects written in Django. Previously, everything was running fine, but today when i tried to sign into the Django admin page it gave me this error: 403 Forbidden And returned this in my terminal: Forbidden (Permission denied): /admin/auth/group/add/ raise PermissionDenied django.core.exceptions.PermissionDenied Which confused me, since there was already a superuser created. Can anyone help me solve this?
