django inspectdb ORA-00904 "IDENTITY_COLUMN"
I'm currently trying to get Django (version 2.1.5) models from existing Oracle 11 database by python manage.py inspectdb, but this error still occurs: # Unable to inspect table table_name # The error was: ORA-00904: "IDENTITY_COLUMN": invalid identifier I've tried to use different Djangos. E.g. with 2.0, error didn't occur, but no text for models was created. Another questions from this topic here on SO were not helpful. Based on this link, I think error occurs because I have no primary key in the table, but since I'm not sure, I don't want to make any changes to existings database. Does anybody solved this problem? -

Celery use Django Result Backend on Remote tasks
I have a Django application that use Celery to create async tasks. Some of these tasks live within the Django project and other live on a remote worker with its own code base. I currently use the django-celery-results package to store the results of task calls within the Django database so that I can easily query the status of calls using the Django ORM. This works fine when I call my "local" tasks, but it does not seem to work as well when I call remote tasks. For example: app.send_task("django.foo") # Return status SUCCESS and store result in DB app.send_task("remote.bar") # Stuck in PENDING and never create result in DB By reading the Celery Docs I found out that tasks can be stuck in PENDING if the client and worker doesn't use the same CELERY_RESULT_BACKEND setting. In this case I can't use the django-db backend on my remote worker, since it's not a Django application. So in this case... How do I store my results when doing remote calls in this manner? Note that in the case of remote.bar, I confirm that the remote worker receives the message and executes the method. Its just that my client (Django App) doesn't … -

How do I write a Django ORM query with a relation that isn't defined in the model?
I'm using Django and Python 3.7. I have the following two models in my models.py file ... class Article(models.Model): created_on = models.DateTimeField(default=datetime.now) ... class ArticleStat(models.Model): article = models.ForeignKey(Article, on_delete=models.CASCADE, ) elapsed_time_in_seconds = models.IntegerField(default=0, null=False) I would like to write a Django ORM query where I select articles have a stat that's at least 5 minutes (300 seconds) old. However, I don't know how to reference the ArticleStat object from the Article object. Unsurprisingly, this Article.objects.filter(articlestat.elapsed_time_in_seconds.lte==300) produces a NameError: name 'articlestat' is not defined error. -

How to loop through extended user model fields in Django template?

I am having a difficult time understanding the connection between app_name and namespace. consider the project level urls.py from django.urls import path, include urlpatterns = [ path('blog/', include('blog.urls', namespace='blog')), ] consider the app level (blog) urls.py from django.urls import path from . import views app_name = 'blog' urlpatterns = [ path('', views.post_list, name='post_list'), path('<int:year>/<int:month>/<int:day>/<slug:post>/', views.post_detail, name='post_detail'), ] if I comment out app_name, I get the following. 'Specifying a namespace in include() without providing an app_name ' django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. If I rename app_name to some arbitrary string, I don't get an error. app_name = 'x' I've read the documentation but its still not clicking. Can someone tell me how/why app_name and namespace are connected and why are they allowed to have different string values? -
Django 2.1 Model Observers
Does DJango 2.1 have any support for observers on models? I've looked into https://github.com/lambdalisue/django-observer, but it appears to only support up to 1.6. My goal is that everytime a model is updated, I want to fire and command that executes other functions. -
Django generics.ListAPIView accepting POST method
I have a Django view which extends generics.ListAPIView. It works fine with get requests, however since the char limits of the URL, now I need to send the request via POST. It is the same request, the only thing I need to change is the method to POST. My current code is pretty simple: class MyClass(generics.ListAPIView): serializer_class = MySerializer paginate_by = 1 def get_queryset(self): queryset = SomeClass.objects.all() # do some filtering How could I add POST support to this class? -
