Django is giving different date values for objects accessed via queryset
Context I get different values for datetime field when I access them differently. I am sure there is some utc edge magic going on here. (Pdb++) Foo.objects.all().values_list('gated_out__occurred__date')[0][0] datetime.date(2021, 9, 9) (Pdb++) Foo.objects.all()[0].gated_out.occurred.date() datetime.date(2021, 9, 10) How do I fix/figure out what is happening? -

The DevSpace-Django tutorial in question is the following: https://devspace.cloud/blog/2019/10/18/deploy-django-to-kubernetes Trying something completely barebones to understand how devspace works to decide if I want to make the switch from skaffold.

AADSTS90102 error when using django-microsoft-auth for SSO with Azure AD
I followed the steps in this tutorial to enable SSO with Azure Active Directory for the admin portion (to start) of my Django app: https://django-microsoft-auth.readthedocs.io/en/latest/usage.html Navigating to /admin yields this page, which is good: Clicking Microsoft brings up this new window: The important error seems to be: AADSTS90102: 'redirect_uri' value must be a valid absolute URI. In this window, I used the browser console and found that a GET request was being made like this: https://login.microsoftonline.com/50ce...90ac7/oauth2/v2.0/authorize?response_type=code&client_id=f4...27&redirect_uri=https,https://example.org/microsoft/auth-callback/&s... Note the redirect_uri=https,https://.... It seems like that leading "https," is superfluous and is causing the problem. Any ideas where that could be coming from? In my Azure app, the redirect URI is set to https://example.org/microsoft/auth-callback/: I'm using Python 3.9.6, Django 3.2, django-microsoft-auth 2.4.0, NGINX 1.18.0, uvicorn 0.14.0 I've searched for help on this and haven't found anything relevant to my situation.

Build fails for Django app running on Heroku
So I'm currently working on a project where I want my Django app to run. The app itself is hosted with Heroku and so, I have a requirements.txt file with the following packages: django-heroku==0.3.1 django==3.2.7 gunicorn==20.1.0 noise==1.2.1 numpy==1.19.2 pandas==1.2.4 scipy==1.6.3 scikit-image==0.17.2 Cython==0.29.23 opencv-python==4.4.0.46 I recently added the Cython and OpenCV packages as I require them for the POT package. However, when I try to deploy the app, the build log says there isn't a module named numpy. I presume this is because numpy hasn't been "installed" yet.

Aggregate for multiple instances with a ManyToOne relation
I am new to Django and I want to build a Website to track boardgames. What I want: For each round played a Player will get points and I want to create a table which shows the sum of all Scores for each Player. My model is as follows: class Player(models.Model): name = models.CharField(max_length=150) class Score(models.Model): player = models.ForeignKey(Player, blank=False, null=False, on_delete=models.PROTECT) scorevalue = models.IntegerField(blank=False, null=False) I would like to get a queryset with all players where an additional field with the sum of his scores is added. In SQL something like Select distinct playername, sum(scorevalue) over (partition by playername) from Players Join Scores My main problem is to understand the connection between "aggregate" and "annotate" functions in combination with instances and querysets. With an instance I can get Player.objects.get(pk=1).score_set.aggregate(score_sum=Sum('scorevalue')) but is it possible to do this for every instance in a queryset? Thanks for the help. -

Django use request.META['HTTP_ORIGIN'] in django sites framework
So I have a task where I have to use django.sites framework in order to filter some objects in ApiViews depending on the client (there are different front-end clients hosted on different domains) which called the api. so www.frontend1.com and www.frontend2.com are calling www.myapi.com The problem is that both of the clients are calling the api and now I have to "divide" it depending on the request.META['HTTP_ORIGIN']. I've red about django.sites framework (I was asked to use it) but this framework should be useful if the site is hosted on different hosts with the samo codebase. But if the host is the same it renders the django.sites framework useless in my case. Or maybe I am wrong. I have to divide the api by site but instead ot HTTP_HOST I should relay on HTTP_ORIGIN. I've come up with two ideas. Override half of the django.sites framework, but im pretty shure that this will be an overkill Create a my own django.sites framework. Honestly I dont need the whole django sites framework, I will just add permissions in the staff users and filter the querysets depending on their rights and for the api I will just create an object_manager in the … -

Celery periodic tasks being processed only if a post and get request is sent to a route containing .delay() and AsyncResult()
I want to run this task for every three minutes and this is what I have tasks.py @shared_task def save_hackathon_to_db(): logger.info('ran') loop = asyncio.get_event_loop() statuses = ['ended', 'open', 'upcoming'] loop.run_until_complete(send_data(statuses)) logger.info('ended') settings.py CELERY_BEAT_SCHEDULE = { "devpost_api_task": { "task": "backend.tasks.save_hackathon_to_db", "schedule": crontab(minute="*/3"), }, } However this doesn't get run every 3 minutes, it only gets run when I send a post request to http://0.0.0.0:8000/hackathon/task followed by a get request to http://0.0.0.0:8000/hackathon/<task_id> This is the code for the functions pertaining to the routes respectively @csrf_exempt def run_task(request): if request.method == 'POST': task = save_hackathon_to_db.delay() return JsonResponse({"task_id": task.id}, status=202) @csrf_exempt def get_status(request, task_id): print(task_id) task_result = AsyncResult(task_id) result = { "task_id": task_id, "task_status": task_result.status, "task_result": task_result.result } return JsonResponse(result, status=200) -
I can't create an object in the python shell because I can't import my app with the line "from products.models import Product"
I'm following a Django tutorial that has us creating an app named products I start the python interpreter in the root folder C:\Users\dancc\dev2\cfeproj using the line python manage.py shell when I run the line from products.models import Product I get the following error message ImportError: cannot import name 'Product' from 'products.models' (C:\Users\dancc\dev2\cfeproj\products\models.py) I read that this was a case of circular import, but I have no idea which file is the cause of it here is every part of files that includes the works with Products models.py #C:\Users\dancc\dev2\cfeproj\products\models.py from django.db import models # Create your models here. class Prodcut(models.Model): title = models.TextField() description = models.TextField() price = models.TextField() summary = models.TextField(default='this is so cool!') settings.py #C:\Users\dancc\dev2\cfeproj\cfehome\settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'products', ] apps.py #C:\Users\dancc\dev2\cfeproj\products\apps.py from django.apps import AppConfig class ProductsConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'products' 0002_summery.py #C:\Users\dancc\dev2\cfeproj\products\migrations\0002_summery.py from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('products', '0001_initial'), ] operations = [ migrations.AddField( model_name='prodcut', name='summery', field=models.TextField(default='this is so cool!'), ), ] I also read that the structure of my files might also be the issue, but I don't want to mess around with the location without fully understanding it. -
How to protect child app urls using auth in a Django DRF API
This is my scenario: I have a legacy db and an Django api that is using it. Now we are developing another package with Django DRF that will be installed in the 'parent' app. The parent app already have oauth authentication. So in the parent app's settings.py REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ('oauth2_provider.contrib.rest_framework.OAuth2Authentication',) } Then the routes are protected under this auth system. This is routes.py: urlpatterns = [ path('api/v1/', include('myapp.routes', namespace='api')), # OAuth 2.0 path('o/', include('oauth2_provider.urls', namespace='oauth2_provider')) ] I install my package, that basically is a DRF API with managed=False models, and it will be an API that will work against the legacy DB. (this is done and working ok) pip install -m my_new_child_package After I install the package and add it's urls I would like to have authentication as well. Basically apply same auth of the parent app. So I am going to have this: urlpatterns = [ path('api/v1/', include('myapp.routes', namespace='api')), path('o/', include('oauth2_provider.urls', namespace='oauth2_provider')) # I want to protect routes under api/v2/ as well with existent auth system. path('api/v2/', include('my_new_child_package.urls')), ] Should I configure something in my child app, or can what other alternative do I have? A middleware? -
