With Django, is there a way to skip locked rows when performing an update?
I can do MyModel.objects.select_for_update(skip_locked=True) to grab rows that aren't locked. However, if I try to append an .update(some_field='whatever') to that, the UPDATE will sill apply to the FULL result set, including locked rows, and it will wait until the locked rows are freed up before executing (i.e. the select_for_update(skip_locked=True) portion is ignored in the update SQL that is sent). The SQL, in that scenario, will look like: UPDATE "my_model" SET "some_field" = 'whatever' I can get around this by first grabbing the IDs of the rows to update and then sending a separate query to update the rows: ids_to_update = list(MyModel.objects.select_for_update(skip_locked=True).values_list('id', flat=True) MyModel.objects.filter(id__in=ids_to_update).update(some_field='whatever') However, that requires 2 hits to the DB instead of 1 (I'm sure there's a way to do it with 1), and the rows that I'm updating, for the task at hand, have hundreds of thousands to millions of matches, so the 2-step approach is very memory-unfriendly and has high failure potential. Is there a non-raw-sql means of obtaining what I'm after with Django? If I have to resort to raw sql, what would that look like? -
How to send POST request with query params in django tests
I have test.py from rest_framework.test import APITestCase from django.core.files.uploadedfile import SimpleUploadedFile from django.urls import reverse class PostImageTest(APITestCase): def setUp(self) -> None: self.product = Product.objects.create(...) self.sampleImage = SimpleUploadedFile("test_image.jpg", b"binary data", content_type="image/jpeg") def test_with_valid_data(self) -> None: data = { "image":self.sampleImage, "is_featured":true } response = client.post(reverse('images'), data, format='multipart') I want to pass query params like images?product=id to the client.post() method. Also i'm not getting as to how to encode the image and send a POST request. When i tried like this response = client.post(reverse('images'), {'product' : self.product.id}, data=data, format='multipart') It gives me this error TypeError: Client.post() got multiple values for argument 'data' -
Chatgpt integration with Django for parallel connection
I'm using Django framework to have multiple chatgpt connection at same time but it's make complete code halt/down until chatgpt response is back. To encounter this i'm using async with Django channels but still its block Django server to serve any other resource. This is command to run Django server daphne --ping-interval 10 --ping-timeout 600 -b 0.0.0.0 -p 8000 backend.gradingly.asgi:application this is code which is calling chatgpt model = "gpt-4-0314" thread = threading.Thread(target=self.call_gpt_api, args=(prompt,model,context,)) thread.start() this is python code which is sending response to channels async_to_sync(channel_layer.group_send)( f'user_{context["current_user"]}',{ "type": "send_message", "text": json.dumps(json_data) } ) -
CSRF issue in the Django webpage deployed via Kubernetes pod
I am trying to deploy my web application that is written in Django, the image is build and already there, I am just deploying that image into a Kubernetes pod and running it. There is also an nginx pod that runs here. When I am trying to application via the pod and the port exposed through nginx, the error that I am getting is Forbidden (403) CSRF verification failed. Request aborted. I cannot change anything in the application directly. I am not posting the deployment file here as it is too big of a file, and there there is configmap and pv also involved in the backend. The application runs on http at the moment. The application takes me to the login page and after providing credentials it gives me this error. What are some of the things that I can try out. -

Structuring Docker Compose for larger Django backends
I'm currently trying to set up my backend with Docker Compose. I successfully managed to integrate my PostgreSQL database, my Django backend service as well as RabbitMQ message broker with each other. What I'm trying to achieve is setting up Celery workers, Celery beat and Celery Flower in separate Docker containers so my Django backend can work with them. The problem: My Celery tasks need to access Django's models and the database. Therefore, I need to copy some backend files into the Celery containers as well. I just don't feel like it's the best way to do that. I need to copy my entire backend, containing my tasks, routines, models, urls and views to get my Celery workers to actually run. What would be the best workflow to realize that? -

Django allauth - SocialTokens table empty after Google Login
Python: 3.8.10 Django: 4.1.7 django-allauth: 0.54.0 I'm working on a webpage which I have to connect to the Company Google Workspace. I correctly managed the login, with no issues. Now, I have to connect to the Gmail of the authenticated user. For connecting to Google Apps I need a Token that, as I understood, should be in the Database in the table SocialTokens (automatically filled-in after the login phase). I populated Sites and Social Application manually, and rightly (I guess) based on fact that login works. The authentication works properly, but after the login the model SocialToken (table "Social application tokens") is still empty. But I cannot figure out why the table SocialTokens is not populated after the correct Google login. Here my settings.py SITE_ID = 1 INSTALLED_APPS = [ 'django.contrib.admin', ..., 'allauth', 'allauth.account', 'allauth.socialaccount', 'allauth.socialaccount.providers.google', ] SOCIALACCOUNT_PROVIDERS = { 'google':{ 'SCOPE': [ 'profile', 'email', ], 'AUTH_PARAMS': {'access_type':'offline'}, } } SOCIALACCOUNT_STORE_TOKEN = True SOCIALACCOUNT_AUTO_SIGNUP = True I tried what below: update django-allauth (0.4 --> 0.54) SOCIALACCOUNT_STORE_TOKEN = True --> set False, True and unset(commented and deleted) SOCIALACCOUNT_AUTO_SIGNUP = True --> set False, True and unset(commented and deleted) two lines above in all their combinations (es.

Image upload for image processing to fill up related form fields in Django
I am new to Django. My task is to upload an image and do some image processing on it and fill up some fields based on the results obtained from the image. Then the user would maybe check if the values that get filled in are correct and if they are they will save the whole form with the image and all the other form fields. So, I am confused about the following. I already have the util functions for the image processing which is in python. How should I obtain the image immediately after the user select the file and do the image processing and receive my data from the processing keeping in mind that this will be happening in the server. My url for this page is "admin/book/add". I am not providing any code because I wanted to the general way of how to do something like this in django.

How do I use a dict to translate ArrayAgg values for an annotation in Django?
I'm using Django 4 with Postgres. Say I have two related models like this: class Company(Model): ... class Address(Model): city = CharField(...) companies = ManyToManyField( Company, through=ThroughCompanyAddress, related_name="addresses" ) ... class ThroughCompanyAddress(Model): company_id = ForeignKey(Company, ...) address_id = ForeignKey(Address, ...) I want to annotate the cities that each company is in. Normally, I would do something like this: Company.objects.all().annotate(cities=ArrayAgg("addresses__city")) Unfortunately, because of the way my DevOps team has the databases configured, these tables are stored on different databases, and I can't do this. Instead, I need to do 2 queries - first, to get a mapping of address ids to city names, and then to somehow use that mapping to annotate them onto the company models. # After the initial query to the first database, I end up with this # Note: The int dict keys are the address model Primary Keys cities = {1: "Paris", 2: "Dubai", 3: "Honk Kong"} # Now how do I use this dict here? Company.objects.all().annotate( city_ids=Subquery( # Not tested, but I think something like this would work ThroughCompanyAddress.objects.filter( company_id=OuterRef('id') ).values("address_id") ) ).annotate(cities=???) How do I use the cities dict in my annotation here to translate city_ids to city names? I probably could do a … -
What does it mean Redis URL must specify one of the following schemes (redis://, rediss://, unix://)
I am getting this error message after a file upload is completed and the redirect is meant to take place.

Log results of asynchronous processes to a database field
I am working on a project using Django and Celery which takes large files and processes them in multiple steps. The main object for the file is called Sequencing and only one is created per file. Now for every Sequencing we create many samples, variations etc. Some of these are already in the db so we use a get or create. After the processing of each Sequencing, I would like to have the amount of created and the amount of reused objects written into a json field called metadata in the Sequencing object but as some processes run asynchronously, this does not work out. Some code excerpts: models.py: class Sequencing(...): metadata = models.JSONField( default=dict, blank=True, ) def log(self, level: str, msg: str | list, *args, **kwargs) -> None: """Records messages for users in metadata.""" if "log" not in self.metadata: self.metadata["log"] = [] self.metadata["log"].append( { "date": datetime.datetime.utcnow().isoformat(), "level": level, "msg": msg, } ) self.save() def load(self) -> None: chain( ... sequencing_load_variants.si(self.id), ... ) def load_variants(self) -> None: ... for contig in contigs: sequencing_load_variants_by_contig.delay(self.pk, contig=contig) def load_variants_by_contig(self, contig: str) -> None: # create samples # create variants .... self.log( "info", [f"Variants created for region {region.seqid}: {log_dict['variants_create']}"] + [f"Variants found for region {region.seqid}: … -
