Not able to Proxy Apache properly
I use a Django application. I want to access it via Apache. So, I've made DEBUG=False and tried to proxy ProxyPass "/" "http://localhost:8000/" So it routes to my application. Only problem is.. the static files don't load with this method. Therefore, I tried to put static folder in /var/www/html/static In console, this is where all the calls are going but they still don't load. This is my config file There must be something i'm missing or do not understand. Can someone please enlighten with some explanation! -
Django: there is no unique constraint matching given keys
I created an extension of the standard user model in models.py called Client. I added a manytomany relationship to it to indicate which clients are related to another: class Client(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) clients = models.ManyToManyField("self", blank=True) This works perfectly fine in my local dev environment where I use python manage.py runserver. However, when I try to run python manage.py migrate on our testing server using a postgresql database, I get the following error: psycopg2.errors.InvalidForeignKey: there is no unique constraint matching given keys for referenced table "content_client" What am I missing here? -
Django Rest Framework upload_to doesn't work as desired
I'm passing callable for image field in my project like this def profile_picture_path(instance, filename): """Path for uploading profile pictures in media directory""" return f"user/profile_picture/{instance.pk}/{filename}" class User(AbstractUser): profile_picture = models.ImageField(_("profile picture"), upload_to=profile_picture_path, null=True, blank=True) When I add a user through the admin panel, the image gets a proper path: user/profile_picture/3/pfp.png. Problem comes when I send a post request to registrate: user/profile_picture/None/pfp.png # views.py @api_view(["POST"]) def register_view(request): """ Register View which takes only post method. """ serializer = UserSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) # serializers.py class UserSerializer(serializers.ModelSerializer): def __init__(self, *args, **kwargs): exclude = kwargs.pop("exclude", None) super().__init__(*args, **kwargs) if exclude is not None: for field_name in exclude: self.fields.pop(field_name) password = serializers.CharField(write_only=True) class Meta: model = User exclude = ["deleted", "deleted_by_cascade"] How can I fix this and get correct path for image uploads? -
using EmailMultiAlternatives in Django but it randomly stopped sending emails
I'm using Django and the email code is within a try except block that also creates a user. The code is creating the user, but when it comes to sending the welcome email, it's suddenly failing, and defaults to the except clause, which notifies the user that an account already exists with that email. After some debugging I realized that all of the code works right up until msg.send(), but this particular code hasn't been touched since February, when the website went live. I don't understand why it stopped working. in my settings.py: EMAIL_HOST_USER = os.getenv('EMAIL_HOST_USER') EMAIL_HOST_PASSWORD = os.getenv('EMAIL_HOST_PASSWORD') EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.mandrillapp.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True in my views.py: htmly = get_template('main/new_account.html') d = {'name': data['first_name'], 'base': os.getenv('HOST_URL')} subject, from_email, to = 'New Account', os.getenv('EMAIL_HOST_USER'), email html_content = htmly.render(d) msg = EmailMultiAlternatives( subject, html_content, from_email, [to]) msg.attach_alternative(html_content, "text/html") try: msg.send() except: print('message did not send') in my terminal: Conflict: /api/user/account/create -

Remove inheritance from model retaining IDs
I have a two classes, one of which inherits from the other class Drink(models.Model): .... class Juice(Drink) .... Now, this was a mistake and I would like to remove the inheritance and have the Juice model to be a normal model Juice(models.Model). Yet, I would like to retain the sequence of IDs that are in the superclass. Due to the inheritance, the superclass has an auto ID field and the subclass has a pointer field (drink_ptr_id). What happens now when I just change the syntax is that django tries to add an auto ID field to the juice model and wants me to set a default value. The obvious problem is that I need the sequence of the supermodel to be copied into the auto ID field of the subclass model and I cannot just add a default value. A second problem - which is rather strange to me - is that the subclass already has an auto-incremented ID field, so there is a clash between the newly created field and the old id field. I tried to follow the advice given in this post: Remove model inheritance and keep id in newly created autofield, which is pretty much a … -
Why isn't Mypy inferring a 3rd-part library function's type?
Considering this code: class ExportView(IndexView): model_admin: Optional[ModelAdmin] = None def export_csv(self) -> HttpResponse | StreamingHttpResponse: fields = getattr(self.model_admin, "csv_export_fields", []) return render_to_csv_response(self.queryset.all().values(*fields)) I get the following error from Mypy on the return line: error: Returning Any from function declared to return "Union[HttpResponse, StreamingHttpResponse]" [no-any-return] render_to_csv_response is a method from django-queryset-csv, and Pyright correctly infer its return type as being a Union[HttpResponse, StreamingHttpResponse]. I thought that Mypy was not reading the 3rd-part library, as if running with --follow-imports=skip, but my pyproject.toml config has set silent, which behaves in the same way as normal [tool.mypy] plugins = ["mypy_django_plugin.main"] disallow_untyped_defs = true ignore_missing_imports = true follow_imports = 'silent' no_incremental = true warn_redundant_casts = true warn_unused_ignores = true warn_return_any = true warn_unreachable = true enable_error_code = 'ignore-without-code' show_error_codes = true Changing it to normal doesn't fix the issue either. Any idea how to get Mypy to find the proper type, like Pyright does out of the box? -

Is there a signal/hook to know when a password reset has been triggered or if a password reset email has been sent in django allauth?
I'm trying to send emails via another service for password reset alone. Django only allows you to set one email provider, but I'm not sure how to delegate different emails to different email providers. Is this possible to do by listening to a signal like password_reset_sent or something similar? What I want to achieve is this: Default email sending: use client X if password reset email sending: use client Y Is this possible using django allauth? -
Django With Apache And mod_wsgi: Memory Leak?
My problem is that over time the memory usage (especially the virtual memory) increases until the system freezes. Last time the virtual memory of the "/usr/sbin/apache2 -k start" process has used over 8GB virtual memory. It was several days from the last apache2 restart. I have a virtual Machine with 1GB RAM and 15GB HDD where I have Ubuntu 22.04 installed with Apache/2.4.52 over apt with mod_wsgi, a python virtual environment where Django 4.0.5 is installed via pip. I do not run Django in daemon mode but in the "default" mode. I changed nothing in apache2.conf. My site-configuration looks like this: WSGIPythonHome /var/www/venv WSGIPythonPath /var/www/venv/fye_backend <VirtualHost *:80> ServerAdmin (my email) WSGIScriptAlias / /var/www/venv/fye_backend/fye/wsgi.py ErrorLog /var/www/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> I server the files like this code (in views.py): def example(request): key = request.GET.get("key") some_info = some_model.objects.get(key) return HttpResponse(some_info) 1 Day current Virtual Memory usage 1 Day current RAM usage If more information is needed please let me know.

Django Rest Framework JWT authentication - user logged in after drop database
Like I mentioned in the title. I have a DjangoRestFramework application which uses JWT token authentication on the backend. The issue occurs when I log as user, and save the token in the cookies. Next, I drop the database, and create same user with same credential programatically on the backend. Finally when I open the browser, the user is still logged in, although technically the whole database was wiped out, and set up from scratch. Is this the expected behaviour for JWT or maybe there is a way to make sure, that those tokens expire when database is dropped ? Thanks -
Django: How to get value in one model from the other model?
It feels like a very simple question, but how to get value in one model from the other one in django? I have my models.py like this: class Patient(models.Model): id = models.AutoField(primary_key=True, verbose_name='Patient ID') class Salvage_Treatment(models.Model): id = models.AutoField(primary_key=True) id_patient = models.ForeignKey(Patient, on_delete=models.CASCADE) Salvage_treatment_end_date = models.DateField() class Survival_Parameters(models.Model): id = models.AutoField(primary_key=True) salv_treat = models.ForeignKey(Salvage_Treatment, on_delete=models.CASCADE) salvage_treatment_end_date = models.DateField() id_patient = models.ForeignKey('Patient', on_delete=models.CASCADE) Let's assume that I have a patient with id_patient = 2 and I fullfiled the Salvage_Treatment form for him with id=1 (id of this form) and some date in Salvage_treatment_end_date. Now I need to have this same date to be put automatically in Survival_Parameters.salvage_treatment_end_date. How can I do that? I don't want to choose which Salvage_Treatment form to get the data from - instead I ONLY want to select the patient's ID. -
