Django csv upload to db works but throws error
I have created an app named customer within a project named Website using django. I have created a csv upload in the admin area which is connected to the Postgres db. An error occurs when I upload the CSV returning: Exception Type: IndexError Exception Value: list index out of range However the CSV file is still added to the db but the error screen is displayed. Even more strangely if I a notepad doc as csv containing the data and upload that I get no error until I try to upload a second data set. If I save an excel doc as csv I get the error. Where am I going wrong ?

How to load sql dump in a containerized django docker which depends on postgres
I am running a Django container on docker which depends on Postgres. Now the issue is, when I try to load the postgresql docker-compose up cat /tmp/dump.sql | sudo docker exec -i <container_id> psql -U <user> -d <database_name> This imports the first few tables and gives me a lot of errors on the terminal An example constraint "table_id" for relation "table_name" already exists Another example null value in column "column_name" violates not-null constraint Another one insert or update on table "table_1" violates foreign key constraint "table_id" I wanted to know is this even the right way to import this data. Plus I cant seem to drop the database as it is already being used by django. Note: I tried with volumes where I imported the db with postgresql. But everytime I run django, the database gets reset. I am guessing it has something to do with the migrations, but I can't touch that part. -

Celery redis result backend type conversion
We have been using redis as a celery backend for a lot of time. Recently, we decided to store some json data in it . So here comes the problem: after retrieving result from celery data through AsyncResult(task_id) data such as {True:10,False:1} becomes {1:10,0:1}. Probably because redis has no boolean type in it's core. Keeping results with boolean keys is crucial for our system. I've tried to add CELERY_RESULT_SERIALIZER = 'json' into config with no effect. Is there any solution for this? -

My k8s liveness probe isn't setting the Host
I'm trying to deploy a Django app with startup and liveness probes configured. As it's a Django app, I need the Host header on the probes to match something permitted in my ALLOWED_HOSTS. As my probes are both httpGet checks, the simplest solution seems like it would be to use the httpHeaders field as suggested in the kubernetes docs. This seems to work for the startupProbe, however it's not working for the livenessProbe. Sanitized version of my probes: livenessProbe: httpGet: httpHeaders: - name: Host value: k8s-probes path: /health/liveness port: http scheme: HTTP startupProbe: httpGet: httpHeaders: - name: Host value: k8s-probes path: /health/ port: http scheme: HTTP When the pod startups up, I see 200 responses to the initial startup probes, then once the liveness probe starts, I get 400 responses with the error that the pod IP address isn't in ALLOWED_HOSTS, indicating k8s isn't setting the Host header I've defined for the liveness probe. -

How can I use Speech Recognition in Django on the client side?
I am writing an application in Django. There should be a field to fill in, which the user should be able to fill in by voice. He should see what he dictated and, if an error occurs, be able to fix it quickly. I wrote an html file with a small script in js inside. Here are its contents: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <input id="the_button" type="button" value="Click to Speak"> <input id="the_form" type="text" name="q" size=80 > <script type="text/javascript"> var SpeechRecognition = new (window.SpeechRecognition || window.webkitSpeechRecognition || window.mozSpeechRecognition || window.msSpeechRecognition)(); const the_button = document.getElementById("the_button"); the_button.addEventListener('click', function(event) { SpeechRecognition.start(); }) SpeechRecognition.onresult = function(event){ var the_text = event.results[0][0].transcript; document.getElementById('the_form').value = the_text; }; SpeechRecognition.onend = function(){ SpeechRecognition.stop(); }; </script> </body> </html> This html file works fine when I open it in the browser. But when I integrate this file into my Django project in the developer console I get an error in the line: var SpeechRecognition = new (window.SpeechRecognition || window.webkitSpeechRecognition || window.mozSpeechRecognition || window.msSpeechRecognition)(); I installed SpeechRecognition modules in my Django project, it doesn't seem to have anything to do with my problem. I would be grateful for any advice on … -
Django change external user-facing field name
I have a model that will have two similar "id"-like fields. One will be the primary key, one will be the a human-readable id. On the backed/in the model, I have differentiated them as such pk_id = models.AutoField(primary_key=True) # internal only, incrementing int ext_id = models.CharField(max_length=128) # external facing, words+int When the user does a query to get a list of the models, I want to EXCLUDE pk_id entirely, and have ext_id appear simply under the name id. Like this: { 'id' : 'name_title_001' # same as ext_id 'other_fields' : 'bla bla bla' } How do I accomplish this?
