Does Heroku provide any VPN client like AWS Client VPN?
I want to host a database in Heroku server and also a django application. The problem is: To transfer data to my Heroku database i would need be connected to a VPN. Does Heroku provides a way to connect to a VPN in order to access another database, like AWS client VPN? My infra would be like this: Airflow running DAGs to pull data from a AWS database that requires VPN connection to source from it. I would transfer the data from this AWS database to my heroku database. Is it possible? Thank you Another thing that i'm wondering is if it is possible to connect Heroku to AWS client VPN, in case Heroku does not have something similar or a way to do this step. -

Django MySQL UUID
I had a django model field which was working in the default sqlite db: uuid = models.TextField(default=uuid.uuid4, editable=False, unique=True). However, when I tried to migrate to MySQL, I got the error: django.db.utils.OperationalError: (1170, "BLOB/TEXT column 'uuid' used in key specification without a key length") The first thing I tried was removing the unique=True, but I got the same error. Next, since I had another field (which successfully migrated ): id = models.UUIDField(default=uuid.uuid4, editable=False) I tried changing uuid to UUIDField, but I still get the same error. Finally, I changed uuid to: uuid = models.TextField(editable=False) But I am still getting the same error when migrating (DROP all the tables, makemigrations, migrate --run-syncdb). Ideally, I want to have a UUIDField or TextField with default = uuid.uuid4, editable = False, and unique = True, but I am fine doing these tasks in the view when creating the object. -

Django - generate a unique suffix to an uploaded file (uuid is cut and django adds another suffix)
I'm going to use DigitalOcean Spaces as a file storage and I want to add suffixes to uploaded filenames for two reasons: impossible to guess file url with bruteforce ensure it is unique, as I'm not sure if Django can check for filename uniqueness on S3 This is the method: def cloudfile_upload_to(instance, filename): path = storage_path_service.StoragePathService.cloud_dir(instance.cloud) filename, ext = os.path.splitext(filename) _uuid = uuid.uuid4() return os.path.join(path, f"{filename}-{uuid}{ext}") in the code: path == "user/11449_bacccbe4-6794-42e3-89c3-5045b024fa11/income/1541/cloud" filename, ext = "webp", ".webp" uuid == "f8851579-3aa6-403b-bc08-86923d72e80b" When I check the file it is in a correct dir, but the filename is: "webp-527846f0-4284-4e_YvqcSrf.webp" AS you can see, uuid is cut and Django adds it's own suffix.

Category Filters and Store Item Options Django
I can't figure out how to make filters for each product category of the Django store. Suppose we have a category "phones" this category should have filters: screen size, OS, brand, etc. and also we have a category "plywood" whose filters should look like this: thickness, grade, dimensions, etc. How can I build such an architecture so that it would be possible to create through the Django admin panel: store items, item parameters (for future filtering), item categories, a set of filters for the item category. We need a scalable solution to this problem. Please help! I do not often ask questions on this resource, but here I have already spent 4 days but have not found a solution to this problem. I tried many different things, as an example, I tried to create a CategoryOptions (category options) model that contained a BooleanField of all possible filters and then based on the BooleanFields that are set to True, I tried to dynamically generate fields for the ItemOptions (store item options) model on based on the CategoryOptions model. Here is the code for one of my unsuccessful attempts (rough sketch) - class CategoryOptions(models.Model): size = models.BooleanField(db_index=True, default=False) format = models.BooleanField(db_index=True, default=False) … -
Django - Whatsapp Sessions for scheduled messages
Goodnight. I'm developing a system where users, in addition to all the bureaucratic part, can register their clients' whatsapp so that automatic billing messages, congratulations, etc. are sent. Where the user would read the QR code and the system would be in charge of sending messages over time, using the user's whatsapp, thus opening a user<-> clinet conversation. I'm dividing this problem into parts, for now I'm trying to read the Whatsapp Web Qr Code and display it in a template. This is already happening. The problem is that the webdriver is terminated first, as soon as the image is returned to the template, so the session cannot be validated.

How to download Spatialite Library with MacOs (Django)

Huge time latency between nginx and upstream django backdend
So we have a setup of nginx ingress controller as reverse proxy for a django based backend app in production (GKE k8s cluster). We have used opentelemetry to trace this entire stack(Signoz being the actual tool). One of our most critical api is validate-cart. And we have observed that this api sometimes take a lotta time, like 10-20 seconds and even more. But if we look at the trace of one of such request in Signoz, the actual backend takes very less time like 100ms but the total trace starting from nginx shows 29+ seconds. As you can see from the screen shot attached. And looking at the p99 latency, the nginx service has way bigger spikes than the order. This graph is populated for the same validate-cart api. Have been banging my head around this for quite some time and i am still stuck. I am assuimg there might be some case of request being queued at either nginx or django layer. But i am trusting otel libraries that are used to trace django, to start the trace the moment it hit django layer and since there isn't a big latency at django layer, issue might be at nginx … -

Django returns 'TemplateDoesNotExist' when using Crispy Forms

Trying to restric a queryset in Django base on foreign key relationship
I am trying to make a form in Django that gives the user a limited selection based on a foreign key. To be more exact, the form has 2 fields, a ModelChoiceField and a simple text field.
