Django filer - PolymorphicTypeInvalid ContentType 37 does not point to a subclass
I am using django-filer to handle uploading images in my Django app. I am currently trying to load data from MySQL to PostgreSQL database. I have used the following commands to get data from MySQL and move it t PostgreSQL: python manage.py dumpdata myapp> myapp.json set DJANGO_SETTINGS_MODULE=myproject.settings.production python manage.py loaddata "myapp.json" All content works fine and I can see in pgAdmin4 that it's been successfully exported however when I am trying to open a website that contains images I get Internal Server Error like this: PolymorphicTypeInvalid at /myapp/homepage ContentType 37 for <class 'django_comments_xtd.models.BlackListedDomain'> #205 does not point to a subclass! Or error like this: PolymorphicTypeInvalid at /admin/myapp/articles/30/change/ ContentType 37 for <class 'django_comments_xtd.models.BlackListedDomain'> #232 does not point to a subclass! How can I get rid of this error and how can I move all image paths from MySQL to PostgreSQL? -
Creating a model instance
I have two Models, (Doctor & Patient), the Doctor Model is the parent Model, How can I make (Service_doctor) field be an instance of the Doctor's Model so that I can get the Doctor's name into the Patient's Model using for loop in the HTML Template.

Transform python requests's exceptions to django-rest-framework's API exceptions
I'm developing a REST API using django-rest-framework that needs to interact with a 3rd party API. I use requests for comunication with this 3rd party API. Some recurrent pattern I get in my code is making a request from an APIView handler def calculate_order(order): url = f"https://api.anotherservice.com/orders/calculate/" try: response = requests.post(url, json=order.data) response.raise_for_status() # TODO: handle errors, just printing and re-raising for now except requests.exceptions.HTTPError as errh: raise errh except requests.exceptions.ConnectionError as errc: print(errc) raise errc except requests.exceptions.Timeout as errt: print(errt) raise errt except requests.exceptions.RequestException as err: print(err) raise err return response.json() # ... In my view def post(self, request, *args, **kwargs): # ... Some preprocessing code here order_calculated = calculate_order(order) return Response(order_calculated, status=HTTP_200_OK) DRF implements a mechanism that hanldes Subclasses of APIException raised inside REST framework. Django's Http404 exception. Django's PermissionDenied exception. I was wondering if there's a package for transforming requests's exceptions to exceptions objects that DRF can handle. Also I'll be glad to know any recomendation on how this should be implemented (best practices). I was googling it but terms with "Django" and "requests" drop results mostly of Django itself. -
Using an API to generate virtual numbers
I will build a website of virtual numbers, where the user can buy a number for a certain period of time and, after registering on a platform that requires a number to send a code, my website will receive the code through a webhook and return to the user. The central question is: which service fits my need? I thank. -

Django: Match two models by same field they have
I have 2 models. User model class User(TimeStampedModel): phone_number = models.CharField( _('Phone number'), null=True, blank=True, max_length=30, ) reservations = models.ManyToManyField( 'Reservation', related_name='Users', verbose_name=_('Reservations'), ) and Reservation model: class Reservation(TimeStampedModel): phone_number = models.CharField( _('Phone number'), null=True, blank=True, max_length=30, ) As you see there is ManyToManyField relationship between them. Here I need to get one user that phone_number is same with Reservation model's phone_number How can I get that one user -
Network: My web app goes down and I get "Connection Refused"
I have a serious network problem that is making me go crazy. My web application uses a Nginx web server, all deployed with Docker. We have two network cards with two different IP addresses. because 1 is for 100% uptime and providing external services like a static public IP address. And the other is for internal uses, like an SSH connection. And, therefore, I have a DNS service with two public IPs of type A to serve the website if one is unavailable. I have my nginx webserver configured to serve the two adresses, maybe I should change that. ` upstream app { server 192.168.1.84:5001; server 172.16.31.10:5001; } server { listen 443 ssl; ssl_certificate /etc/ssl/ssl.pem; ssl_certificate_key /etc/ssl/ssl-key.key; server_name example.com; root /var/www/example.com; resolver 127.0.0.11 ipv6=off; index index.html index.htm index.nginx-debian.html; charset utf-8; #max upload size client_max_body_size 75M; location /media { alias /app/media; } location /staticfiles { alias /app/assets; } location / { proxy_set_header Host $host; proxy_redirect off; proxy_pass http://app; # Add your own server port here instead of 5000. proxy_set_header X-Forwarded-Host $server_name; proxy_set_header X-Real-IP $remote_addr; include /etc/nginx/uwsgi_params; } } ` It worked at 100% uptime before; maybe this is related to having two networks now.

Pass HTML as agrumnet within inclusion tag
I have created an inclusion tag for creating a certain number of columns within a row: <tr> {% for col in cols %}<td>{{ col }}</td>{% endfor %} </tr> My inclusion_tag function is: @register.inclusion_tag("row_with_cols.html") def row_with_cols(*cols): return {"cols": cols} So I can now pass as many values I want to my rows as I want with something like: {% row_with_cols "Full name" session.userinfo.name %} This is all well and good however to take this to the next level I would like to pass in arguments that are HTML arguments. For example, I want to turn something like this: <tr> <td>Image</td> <td> <img src="{{ session.userinfo.picture }}"> </td> </tr> into {% row_with_cols "Image" <img src="{{ session.userinfo.picture }}"> %} However, this gives me Could not parse the remainder: '<img' from '<img' I know I could modify the inclusion_tag function with some additional arguments that could provide the info but was hoping to keep that nice and generic. It would be helpful if someone can either tell me whether what I'm doing is not possible or if there is a clean/non-hacky way to do it. Thanks -

Django, spawn worker process on start generates django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet
Background: I have an app that scrapes through our IT infrastructure resources (vCenter, storage, and backup entities) to pull things into a central inventory for quick reference. Each collection spins up in its own thread, and I've taken measures to implement a producer/consumer setup to better scale for our resources. What I've noticed is that when I have collections running from multiple types (Ex: vCenter and storage), the web interface chugs. My thought is because I've got a ton of threads running from multiple sources and the GIL is causing everything to get queued up under one main thread. So, I thought that I could have the main producer/consumer model run as processes instead of threads since they are fairly independent of each other. What's wrong: When I made the code switch from spinning up threads to processes, the worker process tries to load up the models that it should, but it fails because the sub process is separate, and the applications aren't loaded up. It throws django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. What I have found is since this spawned process doesn't inherit anything from the Django main process, it's trying to access the models without having anything started. What … -

Correct way to use DRF and viewsets
I have a model: class Definition(Model): definition_id = BigAutoField(primary_key=True) definition_name = CharField(max_length=50) is_active, created_by, created_datetime, last_modified_by, last_modified_datetime = default_model_attrs() class Meta: db_table = 'definitions' def __str__(self: Self) -> str: return self.definition_name With this serializer: class DefinitionSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Definition fields = [ 'url', 'definition_id', 'definition_name', 'attributes', 'created_by', 'created_datetime', 'last_modified_by', 'last_modified_datetime', 'is_active', ] read_only_fields = [ 'url', 'definition_id', 'attributes', 'created_by', 'created_datetime', 'last_modified_by', 'last_modified_datetime', 'is_active', ] I tried making a view set for a couple of custom actions on create: class DefinitionViewSet(viewsets.ModelViewSet): """ API endpoint that allows definitions to be viewed or edited. """ queryset = Definition.objects.all().order_by('definition_id') serializer_class = DefinitionSerializer permission_classes = [permissions.IsAuthenticated] def create(self: Self, request: Request, **kwargs: dict[str, Any]) -> Response: if not is_valid_db_object_name(request.data['definition_name']): return Response( { 'message': f"Invalid definition name -> {request.data['definition_name']}", }, status=status.HTTP_400_BAD_REQUEST) definition = Definition( definition_name=request.data['definition_name'], created_by=request.user, last_modified_by=request.user ) serializer = self.serializer_class(definition, context={'request': request}, partial=True) definition.save() return Response( data=serializer.data, status=status.HTTP_201_CREATED ) But this seems overly complicated for validating a field (is_valid_db_object_name is basically a regex) and to add created_by and last_modified_by. Also, trying to figure out how to make definition_name the only possible field that should be passed for creating and editing. Am I on the right path? Also, how would the edit method look … -

Django translate salutation
Assume we have person definitions, e.g.: { "first_name": "Peter", "last_name": "Peterson", "academic_title": "Dr", "salutation": "mr" } In english, the salutation should be: def person.display_name(): prefix = person.academic_title if person.academic_title else person.salutation return _(Hello "%(prefix)s {first_name} {last_name}") % {"prefix": prefix} # Dr. Peter Peterson #if the person has a title # Mr. Peter Peterson #if the user has no title In german this definition does not work, as it is always prefix = f"{person.salutation} {person.academic_title} Is there any way to mark it for translations except for def person.display_name(lang): if lang == 'en': prefix = person.academic_title if person.academic_title else person.salutation elif lang == 'de': prefix = f"{person.salutation} {person.academic_title} return _("Hello %(prefix)s {first_name} {last_name}") % {"prefix": prefix} Which has the disadvantage of having two translation strings -
