I am getting ValueError at /car/offer/4/ Cannot assign "4": "CarRent.car" must be a "Car" instance. when trying to save Car instance to form
I am working on a car rental website for uber drivers in django, from the detailView I need drivers to be able to choose the duration of their rental, and other information will be auto filled to the form from my views.py, i was able to get the driver through request.user, i also need the PK of the car to be rented. searching through here i’ve tried various suggestions by people here, but i keep getting one error after another… using self.kwargs['pk'] results in ValueError at /car/offer/4/ Cannot assign "4": "CarRent.car" must be a "Car" instance. then i tried using form.car = Car.objects.get(pk= self.kwargs.get('pk')) which results in a AttributeError at /car/offer/4/ 'CarRent' object has no attribute 'is_valid' can someone please tell me how to get the car instance saved in the CarRent model? any help will be greatly appreciated. Thanks below is my code (reduced to the relevant bit) models.py class Car(models.Model): car_owner = models.ForeignKey(User, related_name='car_owner', on_delete=models.CASCADE) class CarRent(models.Model): car = models.ForeignKey(Car, related_name='rented_car', on_delete=models.CASCADE) driver = models.ForeignKey(User, related_name='driver_renting', on_delete=models.CASCADE) rented_weeks = models.BigIntegerField(default=1, choices=WEEK_CHOICES) forms.py class RentForm(forms.ModelForm): class Meta: model = CarRent fields = ['rented_weeks'] i’m only displaying the rented weeks as that’s the only information i need from the user. … -
Django query content_type by name not content_type_id
I need to count some relations from my Flags model to my Post Model. Now I don't understand how to query for the Post model name at my query, I understand how to query for the content_type_id but not for the content_type (as a string). I got something like this on my mind: Q(models.Q(('app_label', 'App'), ('model', 'Post')) but I don't know how the Syntax has to look like at that point, can smb. help? example: def post_list_most_bad_flags(request): p_counter_query = Flags.objects.filter(content_type_id=12) # --> Want to replace this with content_type instead if content_type_id counter = p_counter_query.count() print(counter) Thanks in advance -
Django Channels ASGI - AppRegistryNotReady: Apps aren't loaded yet
Running my project with python manage.py runserver boots it up perfectly using the channels asgi development server, however when running the project with Daphne (daphne project.routing:application) I get the error AppRegistryNotReady: Apps aren't loaded yet. settings.py INSTALLED_APPS = [ 'channels', 'whitenoise.runserver_nostatic', 'django.contrib.staticfiles', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.sites', # ... # ... installed apps and custom apps ] WSGI_APPLICATION = 'project.wsgi.application' ASGI_APPLICATION = 'project.routing.application' CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [REDIS_URL], } }, } routing.py import os from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter from django.core.asgi import get_asgi_application from django.conf.urls import url from my_app.consumers import MyCustomConsumer os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings") application = ProtocolTypeRouter({ "http": get_asgi_application(), 'websocket': AuthMiddlewareStack( URLRouter([ url(r'^ws/custom/$', MyCustomConsumer), ]) ), }) I have tried adding django.setup() as described in other questions, as well as running with uvicorn instead of daphne but still getting the same error. I've also tried pointing to the websocket routing in settings.CHANNEL_LAYERS['ROUTING'] and moving the application initialization out to an asgi.py file but no luck there either. I can't tell what I'm doing differently from the channels documentation, any help appreciated. -

Django views and requests
How can I catch and process arbitrary request in Django view? For example: def index(request): template_name = 'index.html' users = User.objects.all() return render(request, template_name, {'users': users}) The request parameter here is responsible only for loading the index page, am I right? But how do I process an arbitrary request from front-end, for example, my view has got the data from the database. I need to transfer it to front-end part of my app. How can I do it? Without using context. The request from JS: fetch('index.html', { method: 'GET', }).then(response => response.json()).then(data => console.log(data)) SOMEONE HELP ME I'M TIRED OF SEARCHING THE ANSWER! -

Django REST API nested values updated if exists
I have a Django project where I have a table for Projects, Customers and Contact Persons. Projects have a foreign key to both Customers and Contact Persons, and Contact Persons have a foregin key with Customers. I am using Django REST API to get the data from the server, and when I get a project instance, I would like to be able to see contact persons fields (at least some of them), and when I create/update a Project, I should be able to include a contact person. If the contact person does not exist, it should be created, if it does exist, it might be updated. I have been trying to use Djangos "update_or_create", however, if the contact person already exists, I get a response with "contact person with this name already exists." before I even get into my create function.

How to use tuple in Django expression?
How can I use tuple in Django expressions? I want to be able to annotate QuerySet with some tuple, so that I can make ordering according to that annotation or filter things greater or smaller according to that annotation. I can order by multiple fields (without the need for annotation), but I can't easily filter something without implementing complex logic myself. It would be also nice if this could be used with existing code that uses "greater than" or "less than" filtering. (I could chain bunch of ORs handling things element by element, but I would be surprised if I'm the only one who needs something like this, I don't want to reinvent wheel.) I want standard SQL ordering, where left-most element has highest priority (for example SELECT (1,2) < (3,0) AS TEST returns TRUE). -
Browser blocks cross domain iframe cookies
I have a forum-like component which I use in an iframe on other websites. This component uses django-allauth for authentication with Facebook and Google. Everything worked fine but now the authentication stopped working some time ago. When I look at the cookies in my browser, the cookies from Facebook/Google which are set by the iframe, are not loaded. Although, the cookies from the component itself are set. The authentication still works when I load the iframe on a website which is on another subdomain of the component itself. Tool on another subdomain (working): https://shop-sandbox.adbuddy.be/discussie/ Tool on a totally different domain (not working): https://mama-calinka.webbuddy.be/discussie/ I guess this problem had something to do with CORS-headers but nothing I've tried helped. Can someone help me with this problem please? -

Django + AWS s3 can upload files but not access them
Following this tutorial I set up our system to use Amazons S3 file storage using boto3 and Django-storages. I ran the collectstatic command and it worked just fine, the files show up in the AWS Management Console. But when running the server locally (runserver) all static files are missing. Looking at the console there are the error messages GET https://BUCKET.s3.eu-central-1.amazonaws.com/static/admin/css/nav_sidebar.css net::ERR_ABORTED 403 (Forbidden) for each of the files. The url looks right to me, the upload worked fine, but apparently the access doesn't work. Does this have something to do with my config in AWS? Or is this a django settings issue? -
