Display inline values in other app's admin model
I have been trying to figure it out but since I am not much experienced in this, I wanted to ask if there is a way to display the values from an inline at an other app's model.admin; In my case: accounts\admin.py: @admin.register(models.Customer) class CustomerAdmin(ImportExportModelAdmin, admin.ModelAdmin): list_display = ('first_name', 'last_name', 'customer_subscription', 'company') This is where I want to show inline values. core\admin.py: class ManageAddressInline(GenericStackedInline): model = AssignAddress class CustomCustomerAdmin(CustomerAdmin): inlines = [ManageAddressInline] admin.site.unregister(Customer) admin.site.register(Customer, CustomCustomerAdmin) address_reports\model.py: from django.db import models from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes.fields import GenericForeignKey from django_countries.fields import Country, CountryField from accounts.models import Customer class AssignAddressManager(models.Manager): def get_tags_for(self, obj_type, obj_id): content_type = ContentType.objects.get_for_model(obj_type) return AssignAddress.objects \ .select_related('manage-address') \ .filter( content_type=content_type, object_id=obj_id ) class ManageAddress(models.Model): defined = models.ForeignKey(Customer, on_delete=models.CASCADE) apartment_or_suite = models.CharField(max_length=255) street = models.CharField(max_length=255) city = models.CharField(max_length=255, null=True) postal_code = models.CharField(max_length=20, blank=True) country = CountryField() class AssignAddress(models.Model): objects = AssignAddressManager() apartment_or_suite = models.CharField(max_length=255, null=True) street = models.CharField(max_length=255, null=True) city = models.CharField(max_length=255, null=True) postal_code = models.CharField(max_length=255, null=True) country = CountryField() content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey() address_reports\admin.py: from django.contrib import admin from address_reports.models import ManageAddress @admin.register(ManageAddress) class ManageAddressAdmin(admin.ModelAdmin): search_fields = ['defined', 'apartment_or_suite', 'street', 'city', 'postal_code', 'country'] list_display = ['defined', 'apartment_or_suite', 'street', 'city', 'postal_code', 'country'] … -
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 … -

I launched a django server and now I can't stop the process
Can anyone please tell me how to stop my server? I did like the first few things you need to do in order to commence a django webpage, url pattern, request, HttpResponce etc. and I ran my server but that rocket is still showing on my screen despite trying to kill, pkill, ctrl+pause, ctrl+C.

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 -

Problem with django mysql model auto increment pk (integerfield) number increasing too large
django mysql environment. I have a model that uses the default pk. By the way, pk is increasing too much. It increases by one regularly and then suddenly increases by several thousand. The code to create the model uses bulk_create, but nothing special. Neither is it created and then deleted. The actual model count is about 25,000, but the pk max has already exceeded 10 million. With only a few months of use, it seems to exceed the max of integerfield. How can I make it increment by 1?

Django url link is not working and I can't seem to figure out why
I have a notification that pops up whenever a new article is created and in that notification I have a link to that article. The problem is whenever you hit that link it brings up a 505 error.
