What oauth 2.0 endpoint is used to validate a bearer token
I have an oauth 2 server implemented using django oauth2 provider. I am implementing the client credentials flow in an api.

What endpoint should the api then call on the oauth server to validate this token, when using a back channel? -

Django channels: How to reference ForeignKey and their fields in async context?
I am right now converting a couple of Websocket-Handlers from WebsocketConsumer to AsyncWebsocketConsumer. There is one line that causes problems. The Sync version was: self.mydatacache['workernr'] = school.objects.get(id=myschool).tf_worker.id My first try for an async version was this: self.mydatacache['workernr'] = await school.objects.aget(id=myschool).tf_worker.id Second try: school_object = await school.objects.aget(id=myschool) tf_worker_object = await school_object.tf_worker self.mydatacache['workernr'] = tf_worker_object.id I tried many variations of this, but I always got the same error: You cannot call this from an async context I must be on the completely wrong track here. Any suggestions? -
Audio bytes chunks getting corrupted during streaming using Django and Websockets
I am trying to implement an audio streaming transcription service using django and websockets. The implementation works but the chunks get corrupted after some time like after tenth or eleventh chunk of transcription, while debugging, I discovered that the webm audio bytes extension was missing (which means some other metadata might also be missing in those chunks which makes me unable to transcribe those chunks. class TranscriptConsumer(AsyncWebsocketConsumer): """ Server side implementation of the audio streaming service """ def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.audio_buffer = b'' # Variable to store accumulated audio data I used the audio_buffer variable to concatenate all audio bytes chunks still in an effort to prevent the corruption of data because before using that variable to concatenate the chunks, I experienced the audio bytes corruption after the first chunk.

Multiplying the difference between today and a DateField by a number using Django Models
I'm trying to get the difference in days between the date each row of my table The current date So I can then multiply it by a number. However I keep getting errors and exceptions. I searched Google, the Django docs, but couldn't find how. I even asked ChatGPT and Codeium but they keep giving completely wrong advice and direction.

django add filtes in template is not work expectedly
I am a Django and Python beginner, and I encountered a problem while using Django.

Or is there a better way to determine the page data I need to output based on the model class when multiple models share one template? Thank you all. -

Django app -> Elastic Beanstalk instance deployment instance - Site hanging
I've been following this tutorial to deploy a Django app on AWS EB instance, and got to the eb deploy stage. My log files seem to imply that everything is ok, except the health checker raises some issues: ---------------------------------------- /var/log/nginx/access.log ---------------------------------------- 172.31.2.9 - - [28/Mar/2024:17:00:57 +0000] "GET / HTTP/1.1" 400 154 "-" "ELB-HealthChecker/2.0" "-" 172.31.34.136 - - [28/Mar/2024:17:01:02 +0000] "GET / HTTP/1.1" 400 154 "-" "ELB-HealthChecker/2.0" "-" 172.31.2.9 - - [28/Mar/2024:17:01:12 +0000] "GET / HTTP/1.1" 400 154 "-" "ELB-HealthChecker/2.0" "-" However, I go to the site URL it just hangs and then stops. Could this be because the allowed host url is http and not https, which is not working with Firefox? The loading page issues state: The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Get json field value in sqlite model from view django
I'm trying to get a value from correct_answer key in a JSON field inside a model that is previously fetched from an external API. That value is used in a conditional to redirect (right answer) or render a new question (wrong answer).
